this round absorbs its + confirmed findings and records its refutations. the refutations + matter as much as the fixes: the gesture leak it asked to + self-check is not there (the unhandled paths - gid_begin, + gid_end, the default, the failed decode - all return 0 and the + caller forwards every one of them to defwindowproc, which owns + the info handle; only the handled paths close it themselves; + setgestureconfig's cbsize is the single-struct size the api + wants), and the strip height audit found every view geometry in + the tree riding the one _viv_get_view_top() helper - no + hand-written offsets anywhere. +*the status pane index now reads the official carrier: comctl + fills drawitemstruct.itemid with the drawing pane's index; the + code read itemdata instead - the lparam our own sb_settextw + happens to store there, which equals the index only on the + paths we sent ourselves. a draw arriving any other way fell out + of the range check and returned silently unhandled, leaving the + bare light comctl face - the exact shape of the rc.11 bottom + white bar. the draw reads itemid first (itemdata stays the + compatibility fallback), and an unresolvable pane paints the + strip face instead of painting nothing: a failure shows as a + quiet pane, not a light slab. +*the crash-guard comment told the wrong story: it called the + status bar's ctltype == odt_menu "a historical quirk" - the + words of a stable system behavior. comctl leaves the field + uninitialized on that path (the value is garbage that happens + to look like the menu type), and the comment now says so: a + future maintainer trusting "quirk" could simplify the + control-id routing away and re-detonate the 0x1 dereference + the branch order exists to prevent. the logic did not move. +*the status strip joins the token system: the erase, the pane + fill, the pane text, the size grip fill and dots, and the zoom + editor's field colors all rode hardcoded rgb values or the + dialogs face while the menu bar and the toolbar above them + ride the chrome token - the strip was the one surface a theme + or accent flip could not re-skin. all the sites route through + viv_theme_color / viv_theme_brush now; the dark strip face + moves from the dialogs tone to the chrome tone, so the three + strips read as one chrome. +*the settings window owed its dpi correction: the outer frame + was measured at the viewer's dpi, the window was created with + cw_usedefault, and the layout then ran at the window's own dpi + - a window landing on a different-scaled monitor showed a + frame one size and content another (the probe the author left + recorded the mismatch and never fixed it). the show path now + re-measures the frame at the window's own dpi and sizes it + into place before the first layout - the same correction the + wm_dpichanged branch already applies after a move. +*the settings window can grow: it was a fixed 660x628 dip panel + with no thick frame and no wheel handling - any page whose + content outgrows the design (long locale text, future rows) + would clip its footer out of reach with no escape. the left, + right and bottom edges now report the sizing hit codes (the + system runs its own resize loop on the borderless popup, no + native frame drawn), the minimum track size is the design + size, and the existing wm_size relayout stretches the page. + the title row keeps the drag; the close button keeps its + margin clear of the edge band. +*the startup dpi sync: the init path read the dpi from GetDC(0) + - the primary monitor - and only wm_dpichanged ever refreshed + the globals; a launch restoring the window onto another + monitor would build every strip at the primary's scale, + because a create-time dpichanged is not something the system + documents. one explicit os_window_update_dpi runs after the + main window exists and before the first strip is built from + the globals. +*recorded, deferred on purpose (the review's own advice): the + ~1400 lines of retired options dialog stay frozen in place + until the settings window regains list browsing (the old pages + are the only scrollable command list left), the per-window dpi + refactor (every surface still shares the process globals, each + new surface adding a private bypass) and the resource.h id + splits stay on the debt list, and the dpi probes stay - they + compile to nothing in release and earn their keep the next + time the field reports a dpi oddity. -Sunday, 10 August 2025: Version 1.0.0.13 - fixed an issue with losing the image center on resize - fixed back/forward mouse buttons not working from toolbars - fixed an issue with loading the wrong next image when it was preloaded and changed externally - improved rendering performance - added left click action: move window - added auto size window GUI option +Pre-release: Version 1.1.12-rc.16 (the open intent round) +*the follow-up on the recent-list fix: the guard asked the right + question at the wrong place. "is this the file already on screen" + was answered for every open - including the opens where the user + had just said so: a click on a recent entry, a re-open through + the dialog, a re-drop of the same file. the honest trade of the + last round (clicking the recent entry of the displayed file no + longer re-shuffled it to the top) was that cost, and it is + refunded here. +*the intent is now declared where it is knowable instead of + guessed where it is not: the open-by-name carries a recent-list + policy from its caller. the three user commands (the open dialog, + the drag-drop, the recent click) declare a user open and feed the + recent list unconditionally - the standard mru contract, a + re-open of the displayed file re-tops it. the one path that + cannot know its own intent - the single-instance forward of a + second launch, the re-entry the rotate verb's refresh and the + rotate-then-recheck double-click both ride - declares itself + forwarded and keeps the one honest question: a same-file forward + is a reload, not a recent open, and does not reorder the list. + a forwarded new file still enters the list as a brand-new open, + and the startup command line is vacuously fine (no file is on + screen yet, so the first open still enters the list). -Friday, 25 July 2025: Version 1.0.0.12 - fixed a gdi leak when freeing mipmaps - fixed a gdi leak when refreshing - fixed an issue with loading the wrong next image after changing the sort - added natural sort +Pre-release: Version 1.1.12-rc.15 (the field report round) +*the field report: the recent list, the text proportions, the + shortcut capture hint, and one cross-process hardening. +*"rotating an image lands it wrongly in the recent files list": + the rotate itself never touches the recent list (the audit traced + every writer; the shell verb runs the system's lossless rotation, + the in-memory bitmaps follow). what reorders the list is a silent + re-open: any path that hands the viewer the file already on + screen (the single-instance forward, a re-drop, a re-click, a + re-open of the same file) fed the recent list as if it were a + brand new open - the file jumped to the top with no visible open + anywhere. the push site now asks one question: is this the file + already on screen? a reload is not a recent open. the honest + trade: clicking the recent entry of the file already displayed + no longer re-shuffles it to the top. +*the recent list also kept dead entries: deleting a file left it + in the list until some later click failed, and renaming left the + old name forever (the new one never entered). both operations + maintain their own entry now: the delete drops it, the rename + swaps it in place (the position is kept, nothing jumps). +*"the text proportions look wrong at 4k 225%": the settings window + was the one surface that did not ride the system font size - its + rows carried a 13 dip font while the menu bar, the toolbar, the + message boxes and the classic dialogs all sit on the system font + (12 at 96 dpi). the gap is a fixed ratio: invisible at 96 dpi + (one pixel) and visible at 216 dpi (two to three pixels on every + glyph, the field's own measurements). the settings rows move to + 12 dip and the descriptions to 11 - the sizes coincide with the + message font basis at every dpi, and the dropdowns stop changing + size between the closed value and the open list. +*the status bar never got a font of its own: it ran on whatever + the common control defaulted to, which happens to scale but does + not match the strip's basis. the bar now carries the menu font + (the same one the toolbar and the menu bar ride) and re-pins it + when the dpi changes; the zoom pane editor inherits it through + the same wm_getfont it always used. +*"weird garbled text in the options shortcuts": the capture hint + line under the add / edit / remove buttons ("edit keyboard + shortcut: ") was built by copying the localization string + with the wide-string copier. the localization returns utf-8; + each byte pair became one character of mojibake. the copy is + utf-8 now, and a guard scans the whole tree for the pattern so + no other site can grow it. +*the win7+ hardening: the menu theming finds the system menu + window by class name (#32768) - a name shared by every menu in + every process on the desktop. the find can return another + process's menu; the viewer would theme that one and leave its + own popup plain. both find sites now check the owning process + before touching the class. -Sunday, 20 July 2025: Version 1.0.0.11 - fixed an issue with using the wrong association registry key - fixed a crash when interrupting the loading of a multi-frame image - fixed an issue with displaying images after rotating - fixed an issue with remembering some view settings - fixed an issue with losing the view after toogling fullscreen - inverted increase/descrease slideshow rate - improved preloading next/previous image - added cache last image +Pre-release: Version 1.1.12-rc.14 (the zoom pane editor round) +*the field report on the status bar zoom pane: one click, no box. +*"the zoom percent in the corner needs two clicks to open, and the + click shows a select box": the pane is the click target, but the + click never reached it. the pane's own subclass ate every left + button down on it (the status bar drag anchor inherited from + upstream: hold and drag moves the window) and handed it to the + move loop, which swallowed the button up too - the open command + rides the up, so the box only opened by luck (a click on an + inactive window's orphan up). the anchor is retired: the pane is + pure input now, the drag lives on the toolbar, the menu gaps and + the title bar. +*"the select box": the box itself was a 1998 dialog - a centered + modal frame with a sunken number field, native buttons and a + select-all blue block, never touched by the remade chrome. the + editor is in place now: the pane itself becomes a borderless + number field in the strip's own font and colors (the status bar + answers ctlcolor for it), enter commits, escape cancels, focus + lost commits, typing replaces the selected digits. the dialog + template, its two controls and its two localization strings are + gone; the entry function keeps its name so the click site is + untouched. the system selection color stays (the edit control + offers no custom one) - it lives on four digits for the seconds + the editor is open. +*the empty or zero input keeps the old dialog's contract: ignored. +*the audit round: a canvas click now takes the keyboard home - the + editor held the focus while it lived, so a click on the image left + the arrow and page keys routed into the number field (a dead + navigation zone until enter or escape); the click's focus move is + itself what commits an open editor. +*the 1600% clamp and the view-center anchor carry over unchanged. -Tuesday, 17 June 2025: Version 1.0.0.10 - improved webp memory usage +Pre-release: Version 1.1.12-rc.13 (the non-win11 field round) +*the field report on a windows 10 machine, three roots, fixed. +*"the play button shows pause on an idle photo": the toolbar read the + animation preference bit as the playing state; that bit defaults to 1 + and every image switch resets it to 1, so the pause face sat on every + static image. the face now gates the clock on the frame count (the + ontop rule's own gate), and the five clock-changing paths (the pause + toggle, the frame step and prev, the frame home and end jumps) notify + the toolbar and recompute the on-top window. +*"zoom needs two clicks to work": two roots in the button stepping. + the snap to the nearest multiple of ten could move against the click + direction (a fresh 31% best fit zoomed in to 30 on the first click - + invisible, the visible step only came on the second), and a zoom out + from the best fit hit a dead pos==0 gate written before the below-fit + extension. the snap is direction strict now (out lands on the multiple + strictly below, in on the one strictly above), the floor gate reads the + true ladder floor, and a sparse-zone fallback steps one position when + a ten-point target sits between two ladder positions. +*"it looks bad on non-win11": the remade surfaces leaned on win11-only + dwm attributes with no fallback. the settings window is a borderless + popup that got no shadow at all on windows 10/7 (a bare floating + panel); its dropdowns opened as native string menus with the system + blue highlight and the native checkmark next to the accent pill + sidebar; the light hover token sat ~3 points off the strip and was + invisible; the light settings sidebar equaled the content face + exactly; and the light toolbar carried a private gray between the menu + and button faces. the round: the settings class registers the drop + shadow style off win11, the settings dropdowns ride the owner drawn + menu rows (the same painter, radio dots, one pool per open, the shared + popup theming), the light tokens recalibrate (hover contrast, the nav + layer, the menu-tone strip), and the message box buttons take the + settings window's pill radius. +*the dwm chrome calls double as the platform probe now (the attribute + 33 result latches the answer, os_is_win11 reads it) so every fallback + decision is one honest check instead of a silent no-op. the zoom pill + no longer re-centers its row under an active press. -Thursday, 22 May 2025: Version 1.0.0.9 - added webp support - added animated webp support - added mipmap support for faster resizing - added preload option - added maximized options - added option to copy image - added option to copy filename - added new code signing certificate: voidtools PTY LTD - improved animation timings +Pre-release: Version 1.1.12-rc.12 (the platform guardrails round) +*the import audit's three platform-level roots, fixed and pinned: the + manifest's windows 8.1 supportedOS GUID was a hand-corrupted value + (the first block matched the official guid and the rest did not), so + a windows 8.1 host never matched the 8.1 entry and kept the 8.0 view; + the manifest now carries the official + {1f676c76-80e1-4239-95bb-83d0f6d0da78}, verified against the + microsoft application-manifests documentation. +*unicows is dead weight for a win7+ target: the win32 link lines of + both project files carried UnicoWS.lib straight from the original + upstream import - a windows 9x compatibility stub the modern sdks are + phasing out, and the link dies with lnk1104 the moment an sdk drops + it. nothing in the tree imports an mslu symbol (the x64 configurations + never carried the lib and always linked), so the dependency is deleted + from the vs2019 and vs2026 win32 configurations. the ci legs still + link today (the hosted sdks still ship the stub), so this is the + forward-compatibility clean, not a regression repair. +*wm_dpichanged dereferenced its lparam unconditionally: the system + supplies the suggested rect, but a synthetic message or a compatibility + layer may not, and a null lparam crashed inside the resize. the resize + is now optional - the dpi refresh and re-layout that ride the same + handler still run, only the suggested-rect SetWindowPos is guarded. +*three regression guards pin the round (the official guid present with + the corrupted one absent, the null guard in the dpi handler, no + unicows in either project file), and the version moves to build 54. -Wednesday, 11 October 2017: Version 1.0.0.8b - added ctrl mousewheel action - fixed an issue when only one image was in the playlist - fixed a leak when loading an image - fixed a crash when there was only one shuffled image - improved randomize seeding - fixed a leak when loading an image while already loading an image - -Wednesday, 20 September 2017: Version 1.0.0.7b - added randomized everything search option - added 1:1 scroll option - added rotate options - fixed a bug when navigating to the next image from the first image +Pre-release: Version 1.1.12-rc.11 (the carpet repair round) +*the user's gui remake (rc.8-rc.10) went through a seven-subagent + adversarial carpet review; this round repairs what the review found. + the two headline breaks: the menu bar roots measured empty (the rc.9 + owner draw flip stored no label on the popup rows and the bar kept + reading miim_string - every root collapsed to a blank sliver and the + alt mnemonics died with them; the bar now re-derives the labels from + the live rows) and the status date pane rendered a lone "0" (a wide + format string through the narrow printf parser; the stamp now builds + with the localized getdateformat/gettimeformat pair). +*the viewport geometry caught up with the top strips: the toolbar moved + under the menu bar in rc.8 but the image math still reserved its band + above the status bar - a 40dip dead strip at the bottom and the image + top hidden behind the strips. one view-top helper (menubar + toolbar) + now rides every size computation, paint blit, mouse anchor and scroll + clip, and the zoom pill lands at the viewport bottom instead of + floating one strip high. +*the system theme flip never flushed the token brushes (the half-skinned + ui the field kept catching): the apply path refreshes the cache, heals + the #32768 class brush, and a classic palette change (wm_syscolorchange) + repaints too. +*the toolbar: the play slot resolves from the live state (slideshow + pauses, an animated image toggles the animation clock, idle starts the + windowed slideshow - the fullscreen jump is gone), the faces ride the + theme tokens (the light hover is the quiet 3dlight, not the selection + blue; the private palette duplicate is deleted), the strip background + drag moves the window again (the rebar rule), and the leave tracking + re-arms after a captured press. +*the themed message boxes: owned by the parent (no taskbar button, no + raising the disabled owner), the close button maps to cancel semantics + (an ok box closes as ok), four leaked brushes and a leaked font pair + per box are gone, wm_quit propagates, a second box brings the first to + the front instead of corrupting it, the light box gets a light caption, + the focus ring actually draws (the hpen-as-hbrush no-op), the secondary + button keeps a visible border, the height clamps to the work area, and + the dpi follows the box across monitors. +*the settings window shortcut editor: an unchanged edit confirmed with + enter keeps the binding (it used to delete it), the "currently used by" + row is live during a capture, and modifier combos are capturable again + (ctrl+return - the app's own default - was un-rebindable). +*win 7 closes the dpi ladder: the manifest declares the legacy + dpiaware tag next to the 2016 per-monitor-v2 section (the pre-1607 + loaders ignore the 2016 namespace - without the legacy tag 7 and 8.0 + ran the app dpi-unaware, bitmap-stretched), and the runtime chain ends + with the classic setprocessdpiaware tier. the rc.10 "win 7 keeps the + classic system aware behavior" claim was wrong - unaware, not aware. +*the popup menus: the recent-files header is owner drawn like its + siblings (the type flag landed in fstate, which only takes mfs_ + values, and the row painted in the system look), radio groups draw + the dot, grayed rows never fire from the keyboard, the idle pump + treats the getmessage error return as an error, the owner draw delete + notification is acknowledged, and a slideshow-timer mru rebuild + defers while a popup displays the old rows. +*the pill percent reads the app-wide number (render over native, the + same value the status bar shows - the ladder scale read "100%" at + best fit on a photo the ui called 23%), the failed glyph build never + caches, the double-brace splice leftovers are unwound (the dispatch + is 49 handlers now: wm_deleteitem and wm_syscolorchange joined), and + the pixel probe tooltip correction: it has been dead code since + before rc.7 (the callers were already commented upstream) - the rc.9 + "rides the tokens" line was written into that dead code and is hereby + corrected rather than revived. +*the crash the ci anomaly sweep caught: the comctl status bar sends its + owner-drawn pane draws with ctltype == odt_menu (a historical quirk), + so the menu branch the remake put first cast the pane index - the + itemdata - into a menu row pointer and dereferenced address 0x1 on + every slow-decoded image (the preload pane draws while the load thread + still runs; a fast gif/bmp decode never shows the pane, which is why + the crash looked png-specific). the panes route by the control id + first again, the menu rows after - the baseline's proven + discriminator. stack-captured under cdb on a diagnostic branch (the + fault resolved to the fixed offset 0x486dc in the release map). +*verified: the full tree compiles (zig cc, 98 units, bit-comparable to + the user's build), the three suites pass with 38 new carpet-repair + guards, the link scan stays clean at 111/111, and every fix is pinned. -Thursday, 14 September 2017: Version 1.0.0.6b - added /x /y /width /height /minimal /compact /shuffle /everything command line options. - added jump to list - added everything search - added shuffle - fixed /dc command line option - fixed a bug when opening void image viewer and getting a random filename - -Thursday, 31 August 2017: Version 1.0.0.5b - fixed a bug with move to/copy to - fixed a bug with save as filters +Pre-release: Version 1.1.12-rc.10 (the dpi correctness round) +*fixed the high dpi font bug for real: the per monitor v2 declaration + never shipped in the binary the way it was read - the vs linker merged + the manifest (good), but the zig builds had no manifest at all and the + os_init runtime safety net sat before its own GetProcAddress block, so + the pointers were still null when it ran and it silently never fired. + an unaware process gets bitmap-stretched by the system at high dpi: + every font blurry and oversized. the claim now runs after the api + probes, gains a process wide tier (win10 1703+ SetProcessDpiAwareness +Context) above the per thread tier (1607+) and the win 8.1 shcore + fallback (win 7 keeps the classic system aware behavior), and the zig + build drops a viv.exe.manifest next to the exe for loader level + coverage - three independent layers, all no-ops where unsupported. +*the message box scale follows its parent window's monitor now, not + the stale global logical dpi (mixed-dpi monitor pairs). +*the wndproc domain carried 17 splice-accident double-brace wrappers + with dead DefWindowProc tails; they are unwound (the case exits pin + drops 60 -> 43), the wndproc file is back under the line cap. +*verified under wine: the pre-fix binary renders the settings window + bitmap-stretched to ~2x at 150% scaling; the fixed binary renders it + 1:1 physical and the window self-scales to exactly 1.5x (660x628 -> + 990x942) with the fonts riding the same per-window dip pipeline. +Pre-release: Version 1.1.12-rc.9 (the gui remake round 2 - everything gets the theme) +*the whole ui now draws from one palette: the new viv_theme domain holds +17 semantic tokens x dark/light x five accents (azure, teal, violet, +amber, rose). every surface - the chrome strips, the menus, the dialogs, +the settings window, the zoom pill, the tooltips - resolves its colors +through it, so a theme or accent flip re-skins the app with zero +per surface edits. the accent picks up an ini key (accent_color) and a +swatch row in the settings window, applied live. +*the popup menus are owner drawn now. every visible row carries a tiny +draw record and the painters re-derive the label at draw time from the +command table, the localization table and the live key bindings - a +language or shortcut change can never show a stale row. the rows paint +the theme face, the accent check marks, right aligned shortcuts and +hairline separators; the popup layer gets the #32768 class brush and the +win11 rounded corners plus themed border through the dwm. the unicode +mnemonic scan (wm_menuchar) keeps alt+letter working on the drawn rows. +*the message boxes are the theme panel now: viv_msgbox draws the vector +icon, the wrapped text and the accent primary button, with a real modal +pump (tab/enter/esc). the five messageBox call sites moved over; the +fatal paths in debug/mem keep the native box on purpose. +*the classic dialogs join the theme for real: the dark dialog skin +reads the same tokens (the old hardcoded 202020 palette is gone), and +every dialog frame gets the win11 rounded corners plus the caption +color from the dwm. the old tabbed options dialog route now opens the +remade settings window. +*the zoom pill and the pixel probe tooltip ride the tokens too; the +menubar tokens replace its private brush cache. +*build: zig cc builds the whole tree (build-zig/build.sh, 98 translation +units), msvc-only seh is guarded, and the theme transcribes itself into +the page simulator (scripts/extract-theme.mjs) so the mockup can never +drift from the binary again. +Pre-release: Version 1.1.12-rc.8 (the gui remake round) + *the main window chrome is remade around one palette and three self + drawn strips. the comctl toolbar, its image list, the rebar host and + the pinned button widths are gone: the new viv_toolbar domain paints + a full width command strip (icon plus label buttons - open, previous, + next, slideshow, 1:1, best fit, zoom out, zoom in, rotate and image + info - grouped with hairline separators) with capture based press + tracking, hover faces, disabled states and the overflow rule that + hides whole separator bound groups from the right. the menubar gains + the remake geometry (the strip floors at 28 dip), labels measure with + their hidden accelerators stripped, a pressed root wears its own face, + the popups take tpm_rightbutton so the press drag across items is the + classic one, and a popup follows the mouse across the roots again + (the move onto another root cancels the loop and the same call + reopens there; the idle pump rides wm_enteridle on the owner). + *the zoom pill is one bottom centered row in both modes now: previous, + play/pause, next, a hairline separator, zoom out, the zoom percent and + zoom in - the percent cell renders the ladder value in the menu font + and polls 150ms so wheel and pinch zoom stay fresh; the windowed two + button corner pill is gone. the status bar grew the remake row: the + message pane shows the playlist position and the filename when + nothing else is talking, the pixel rgb pane uses the localized rgb + format, and a date pane pins the local last-modified stamp at the + right edge (the parts cap moved to 8). + *the options dialog is retired from the command path: the new + viv_settings domain opens a frameless-feel settings window (dwm dark + caption, rounded corners) with a three page navigation rail - general, + view, controls - custom drawn dropdowns, toggles, the association + checkbox grid and ok/cancel. the window snapshots the affected config + on open, applies live (language, theme, associations, startup run + key), restores on cancel and saves on ok; every option the old three + pages carried is present. + *the dark palette moves to the remake tokens: chrome faces 0x202024 / + 0x1b1b1e, strokes 0x3a3a40, text 0xe8e8ea over 0x9a9aa0, hover + 0x2e2e33, press 0x38383e. the light ui keeps the system colors. -Saturday, 19 August 2017: Version 1.0.0.4b -

full semicircle ends at + every dpi, one hit test over the button rects, capture based press + tracking with a no-fire-on-drag-away guarantee, and a WM_NCHITTEST + that returns HTTRANSPARENT outside the capsules so a fading pill + never eats clicks on the image behind. + *the windowed pill stays two buttons (zoom out / zoom in) in the + bottom right, the fullscreen bar stays six buttons centered at the + bottom with the idle fade; both modes now share one painter and one + tooltip (rect based, re-targeted on dpi and mode changes), the + keyboard path is real (tab / arrows move the hot capsule, space and + enter fire it), and the disabled state dims the glyphs through + DrawState instead of disappearing. + +Pre-release: Version 1.1.12-rc.6 (the top bar remake round) + *the top bar is remade as a fully self drawn strip: the frame menu is + gone for good - the window is created without one, the bar is a client + side child window (the new viv_menubar domain) that paints every pixel + itself, and the popups are the same HMENU tree opened with + TrackPopupMenuEx. five rounds of field reports lived on the seam where + the system measured and painted the bar and the app patched around it + (the white right strip, the pad capture drifting 5.5x wide, the flip + races); with one painter there is nothing left to race. + *the menu item spacing is identical in both themes: the field + screenshots measured a 17px gap between the labels in the light ui + and a 94px gap in the dark ui - the owner draw measure padded every + label with a "captured system pad" that was really slot-minus-text + compounded through the two measurement systems. the remake uses one + fixed air (4px at 96dpi, rescaled) for both themes, which also + reproduces the light system layout within a pixel. + *the keyboard entry points survive the remake: alt + mnemonic opens + the matching root menu (wm_syschar), f10 opens the first one, the + alt-key underline policy (hidden until alt is held) is kept, and the + popup state refresh that lived in wm_initmenu runs from both + wm_initmenu and the new wm_initmenupopup route. + *the status bar no longer shows the light slab under the dark ui: the + strip erases with the dark face (the comctl status class paints its + own background from the light palette even under the dark theme + class), every pane is registered as owner drawn from the first update + so the pane fills always own the strip (the empty-bar case never drew + anything and showed the bare light face), and the dark pass repaints + the sunken top edge and the size grip with the chrome palette so the + bottom band reads as one dark chrome. + *the toolbar button spacing is pinned: the comctl auto size adapts + each button to its own icon width, so the visual gaps drifted between + the pairs (the zoom pair sat 12px tighter than the prev/next pair) and + the theme re-metrics drifted them again. one uniform button width and + one separator width (tb_setbuttoninfo per index, re-pinned after the + theme flip and the dpi change) keep the spacing identical in both + themes. + *the owner draw menu machinery is deleted with the seam it lived on: + the root item tagging, the draw and measure routes, the pad capture, + the non client tail fill, the theme toggle and the re-measure walk + (502 lines of viv_chrome.c); the menu font cache survives - the remake + measures its labels with it. the splice manifest is the 13 domain + list now (viv_menubar joined), the props register the pair once, and + the dispatch carries 43 handlers (wm_syschar, wm_syskeydown and + wm_initmenupopup joined; wm_measureitem and wm_ncpaint left with their + subjects). + +Pre-release: Version 1.1.12-rc.5 (the structure round) + *the three structure debts the rc series carried are paid. + *the touch gesture cluster is home in the view domain: viv_chrome.c + carried the gesture engine (_viv_on_gesture), the touch click probe + and the double click handler since the one-shot split - chrome is + window dressing, gestures are zoom and pan input; the five engine + statics moved with the functions, chrome no longer references the + cluster at all. + *the window procedure is a domain module: _viv_proc was a 2,208-line + switch; the case bodies are now 42 static per-message handlers in + viv_wndproc.c (the 44 case labels - 41 WM_ messages, two internal + _VIV_WM_ messages and the raw tablet query - collapse to 42 handlers + because two label pairs share a body). the dispatch itself is 95 + lines. every case body moved byte-identical; only the 35 case-exit + break statements became explicit DefWindowProc returns (34 direct + exits plus the touch-double-tap one that sat inside an if-block - + break binds to the nearest loop or switch, and an if-block catches + nothing; the ci compile caught it as a lone c2043), and the two + symbols the handlers share with the core (the background brush, the + command line processor) are externed through viv_state.h (113 -> 114 + externs). the core is 2,431 lines now. + *the splice guard grew the file manifest: the test suite reads viv.c + spliced with every src/viv_*.c (a glob), so a new domain module + changed the measured total silently - the growth window was pinned + against an invisible list. the manifest is pinned now (the core, the + twelve domain modules, the state layer), so adding or renaming a + module without registering it fails the suite. + +Pre-release: Version 1.1.12-rc.4 (the theme race self-heal round) + *the white band is back with two new triggers - opening the options + dialog and switching the theme - and it is a mixed chrome, not a stale + repaint: the system side repaints the frame and the comctl classes in + light asynchronously (the app mode policy flush, the theme broadcast + sweep) while the app level dark answer never flipped, so every re-apply + was gated on was_dark != is_dark and never ran. the delayed recheck + timer and the wm_themechanged handler now re-apply the chrome + unconditionally (the sweep is idempotent), the options combo schedules + the assert after its app mode flush, and the options dialog re-runs its + own full dark pass on a one shot timer so a creation moment that read + an unsettled state heals itself - the caption, the control classes and + all. + *the options navigation tree kept the light explorer class label gray + on the dark face (a themed tree ignores the text color message, and it + read as low contrast): the dark dialog children walk now pins the tree + face and label colors per pass - the same values the initdialog + applies - and hands them back to the system on the light flip. + *the main window erases with the dark chrome face in the dark ui: a + paint that bypasses the handlers must not flash the light class brush + the class still carries (the 1.1.03 lesson, closed for the erase path + too). + *the rc.3 entry core line count corrected: 4,718 as measured (the 4,715 + there was the pre-729c7d7 read; the typedef asserts grew the core by + three lines after that measurement). + +Pre-release: Version 1.1.12-rc.3 (the architecture split round) + *the viv.c monolith is split: 21,129 lines become a 4,718-line core (the + window procedure, startup/shutdown, the command line, the shared state + definitions) plus eleven domain modules - viv_recent, viv_playlist, + viv_load, viv_anim, viv_render, viv_chrome, viv_dark, viv_dialogs, + viv_view, viv_install, viv_menu - and a viv_state.h shared-context + layer, every module under 3,000 lines. pure physical move: function + bodies are byte-identical, the only text edits are the static prefixes + dropped on the 163 cross-module exports and the 113 shared-state + externs (52 single-domain variables moved with their consumers and + keep static; 13 core-private variables are untouched). + *performance and size are unchanged by construction: the projects + already compile with /gl whole-program optimization, so cross-module + inlining survives the split, and exported symbols never enter the + release binary. + *the guard suites read viv.c spliced with every domain module (plus + viv_state.h for the macro guards), so the existing 140+ shape guards + cover the moved code with only optional-static recalibrations; new r70 + guards pin the residual under 5,000 lines, every domain under 3,000, + the pure-move window (spliced total 21,130 -> 21,7xx lines, only + declarations) and the props registration of every new compile unit. + *the spec and the plan carry the r70 one-shot recalibration (the user + released the per-slice pacing; the merged domains, the minimal export + surface and the gate order are documented in the r70 addendum). + *the split's compile hardening (five ci catches between the landing + and this rc): three core states the domains reference left their + static prefixes in the core (the status pane text store, the cursor + visibility flag, the options page id table) and the command table + extern printed after the type that consumes it; the five table-count + macros were sizeof measurements on unsized externs - msvc c resolves + those to zero, so the key-list struct sized its arrays to zero and + the animation, slideshow, options-page and association loops would + all have silently stopped in the domain modules - the macros carry + literals now (154 commands, 21 animation rates, 17 slideshow presets, + 3 options pages, 11 association extensions), each pinned to its real + table by a negative-subscript typedef assert; and a bare-cr line join + the generator fumbled swallowed the light window theme declaration + into a comment in os.h. every class is guarded in the suite. + *the installer association page grows the emf and wmf checkboxes (both + languages, second column): the metafile pair joined the association + table in 1.1.12 but the setup page never offered them, so a setup + install silently skipped the two. the exe-side install switches were + already generic over the extension table (/emf /noemf /wmf /nowmf). + *housekeeping: the vendored libwebp drops the non-windows build + systems, fuzzers and docs (62 files this repository never built), + and Changes.txt keeps its crlf discipline back (an r69 regression + caught by the simulation suite). + +Pre-release: Version 1.1.12-rc.2 (the white band fix round) + + the architecture split decision (r69, documents only): viv.c has + grown to 21,129 lines / 536 functions / 159 file-scope statics with + the window procedure alone at 2,208 lines, and every field fix of + the rc line landed inside that one translation unit. the split now + has a written spec and a written plan (docs/architecture/): the + dialectic (split vs keep, by domain vs by layer, accessors vs a + shared state header, the upstream-shape cost), the decision (a + viv_state.h extern layer first, then eleven domain slices in + measured-closure order, pure physical moves only - no function + body may be rewritten, renamed or reordered), and the guard + strategy (the three suites will read viv.c plus every viv_*.c + spliced in dictionary order so the existing 140+ shape guards + keep covering the moved code without edits). the round itself + changes no C code and ships no binary: the menu-structure suite + gains the r69 guards pinning the documents, the discipline, the + monolith line baseline and the not-yet-existing state layer, so + the split can only shrink the file from here. + + the field report on rc.1: a white band survives the theme flip on + the upper chrome, until a manual resize or refresh brings the dark + face back. the judgment round traced the strip to a chain of gaps, + all on the flip path (the user's 30 second probe - the band dies on + a resize - matched the menu bar candidate, the code evidence + confirmed it and a second strip below it): + - the menu bar strip (the band right of the last top level item): + the flip ends with an immediate repaint sweep over the children + that never carried rdw_frame, and the official semantics keep the + non client area out of a frameless sweep: no wm_ncpaint, so the + dark gap fill that lives in that message never runs, the system + light strip stays until a manual frame change (the one-shot retry + inside the fill only helps when the paint already reached the + bar). the sweep now carries rdw_frame. + - the menu bar item widths: the dark ui measures the top level + items itself (the label at the menu font plus a pad), the light + ui hands them to the system - two measurement systems, so every + flip relayouts the bar (chinese labels accumulate the per item + drift). the pad was a literal 8 at 96 dpi; it is now probed from + the system's own layout (the rect the system gave a top level + item while it was still system drawn, minus its label extent), + cached with the dpi it was captured at and rescaled to the + window dpi, so both themes measure with the system air. + - the toolbar strip (the band right of the buttons): the theme flip + re-metrics the comctl toolbar (the immersive flag, the rebuilt + image list) but never relayouted the strip windows - the dpi + change and the language switch both run the layout. the flip + now runs the same sweep after the image list rebuild. + - the toolbar width: get_wide returned the content span (the union + of the item rects), which loses the first item's left inset twice + against the window the toolbar needs - the rightmost button + could hide (hideclippedbuttons) and the strip behind it widened. + tb_getmaxsize is the official query for the window the toolbar + needs (the total size of all the visible buttons and separators, + wm_user + 83); the content scan stays as the runtime fallback for + the pre 5.80 comctl sets. + - the class brushes: the register wrapper ignored the brush and the + cursor it was given and registered every class with the light + window brush (white) - the rebar caller's own argument was never + in effect, and the zoomui class asked for no brush and got white + anyway. the wrapper honors its parameters now; the rebar passes + no brush (the strip face is painted by theme in the erase and + the paint handlers, a bypassing erase no longer flashes white), + and the main, fullscreen and zoomui classes get what their + callers always wrote (the main and fullscreen windows erase + themselves, so nothing changes there). + the version moves to 1.1.12-rc.2 build 44: the candidate goes back + to the field - the rc.1 acceptance list carries over and the white + band becomes the first check (win11, 150 percent scaling, chinese + ui: flip dark and light five times without touching the window). + +Pre-release: Version 1.1.12-rc.1 (the about line release candidate) + + the first release candidate of the 1.1.12 line: two rounds since + the 1.1.11 stable, both on the about dialog, both hard codes - + the one the 1.1.11 font round put on record, the one the field + made visible once the fonts went per-dpi. + - the about title: the larger face kept the literal 32-pixel + height of the 96 dpi design point (150% drew two thirds of + the intended proportion, 200% half of it). the title now + derives from the live dialog font at the dialog's own dpi - + family, weight and the 8/3 ratio of the message font - and + is rebuilt at every open, so a dpi change between two opens + no longer draws the stale face (b41, the about title hard + code fix round). + - the about band: the dark-mode band chrome (the two separator + lines and the button strip face) moved from the runtime + wm_paint passes into the dialog resource template: the 1-du + line controls and the 24-du strip ride the template grid at + every dpi, the colors travel the control color replies with + the 1.1.11 palettes, and the dialog face answers through the + wm_ctlcolordlg pipeline (b42, the about band template round). + the version moves to 1.1.12-rc.1 build 43: the tag and the + pre-release stay user-gated, the candidate goes through one + full field acceptance (the dark band alignment at every dpi + scale, the light zero-regression, the theme flip refresh) + before the stable line. + +Stable: Version 1.1.12 (the about band template round) + + the dark mode field report on the about dialog: the band chrome (the + two separator lines and the button strip face) was painted at runtime + by a wm_paint case - three fillrect passes whose band edges were + pixel literals (48 and 46 at the 96 dpi design point, scaled by the + system dpi fraction), while the dialog template positions the + buttons in dialog units: two coordinate systems that only met at 96 + dpi. at any other scale (and after the b41 round made the dialog + font per-dpi) the lines drifted off the button strip and the band + boundaries crossed the controls - the rendering the report called + temporary drawing that never reached the resource template. + the fix moves the band chrome into the resource template: + - the geometry: two 1-du line controls (idc_aboutline1, + idc_aboutline2) and one 24-du strip control (idc_aboutband) + declared before the buttons in the idd_about template, so they + sit under them in the z order. the template grid owns the band + layout now: the lines ride the button strip at every dpi, in both + themes, and the dialog font rounds apply to the band as to every + other template control. + - the colors: the wm_paint case is gone. the control color replies + carry the same palettes the passes used (the dark 0x45/0x70 + separator lines and the 0x25 strip face, the light 0xec lines and + the white strip), the banner keeps its 1.1.11 face (the black band + with the white title in the light ui, the shared dark canvas in + the dark), and the dialog face itself answers through the + WM_CTLCOLORDLG pipeline - the official dialog background path, + so the light ui erases white and the dark erases the canvas + color through one contract. + - the about color replies run before the shared dark dialog handler + (its flat 0x20 static reply would flatten the line and strip + faces); every other control keeps the shared pair untouched. + the version moves to 1.1.12 build 42: one dialog, one round, the + tag and the release stay user-gated. +Stable: Version 1.1.12 (the about title hard code fix round) + + the first round after the rollback is one hard code, the one the 1.1.11 + font round itself put on record ("the about title derives its larger + face from it"): the derivation only ever covered the family. the + height stayed the literal 32: + - lf.lfheight = 32 was a 96 dpi design point. the message font scales + with the dialog window dpi (-18 at 150%, -24 at 200%) while the + title stayed 32 pixels on every screen: the 8/3 proportion the + font round promised collapsed to 2/3 at 150% and to 1/2 at 200% - + the title read relatively smaller on every high dpi display. + - the font site was the only one left on the unsuffixed forms: + getobject, logfont and createfontindirect borrow the wide pipeline + from the project-level unicode define, while every other font + site spells the w forms - the wide face name path hung on a + setting outside the code. + - the handle was created once and cached for the process lifetime: + a dpi change between two about opens (a monitor reconfiguration, + a system scale move) kept drawing the stale face. + the fix follows the font round's own derivation rule to the end: + - the title derives from the live dialog font: wm_getfont on the + title control (the shared dialog proc applied the message font at + this dialog window own dpi before this case runs) -> getobjectw + into a logfontw -> the height scaled by 8/3 (the message font is + -12 at 96 dpi and -12 * 8 / 3 = -32: the design point the + literal encoded, now as a ratio that travels with the dpi) -> + createfontindirectw. the family, the weight and the scale all + arrive with the font the dialog actually draws: one type system, + every dpi, both themes. + - the face is rebuilt at every open. the previous handle dies + inside the same message after the control took the new face (a + paint can never interleave the synchronous wm_setfont), and a + creation failure keeps the previous face drawing instead of + handing the control a null font. + the version moves to 1.1.12 build 41: the first round after the + 1.1.12-rc series was deleted from the remote, the number restarts + clean, and the tag and the release stay user-gated. +Stable: Version 1.1.11 (the font unification round) + + the font round unifies the ui type system. the audit locked the + contradiction first: the 1.1.09 unification hard coded every dialog + template to segoe ui 9pt, but segoe ui carries no cjk glyphs - on a + chinese system every dialog label rendered through the gdi per + character font linking fallback with the latin line metrics, while + the menu bar (lfMenuFont) and the status bar (lfStatusFont) draw the + system locale face, microsoft yahei ui. two type systems in one + window: the line heights, the baselines and the glyph density of the + dialog text never matched the menu and status text: + - every dialog takes the system message font now. the shared dialog + proc runs the apply from wm_initdialog, before each dialog's own + case: the dialog window itself and every child control receive + wm_setfont with the message font at the dialog window own dpi + (getdpiforwindow when the os provides it, the tracked dpi + otherwise). segoe ui on an english system, the locale native ui + face on a chinese one - the same family the menu bar and the + status bar draw. one type system, both themes. + - the template face keeps its job: the dlu grid. the dialog manager + sizes the control rectangles from the template font at creation + and the layout stays; only the rendering font follows the message + font (the upstream shipped ms shell dlg 8pt, whose font mapping + picked the locale face - the hard coded segoe ui lost that locale + awareness; the message font restores it without the 8pt skeleton). + - the order matters and the tests pin it: the shared proc runs + before each dialog's own initialization, so the dark flip captures + the native combo field heights against the final font, the about + title derives its larger face from it and the localized labels + render with it. + - the font belongs to the dialog that draws it (the review fix: + the shared cache deleted the handle under the open dialogs - the + options container and its pages coexist and jumpto is a create + dialog too, so a settings broadcast arriving while a dialog stood + open killed the face its controls still held, and the next paint + fell to the default system face): every dialog creates its own + message font at its own dpi, a monitor crossing replaces the face + inside the same message (wm_dpichanged - the old handle dies only + after every child took the new face), the release lands at the + dialog ncdestroy after its children are gone, and the next dialog + reads the fresh metrics at its own open. + - the known limits, on record: a dialog that stands open through a + system font change keeps its face until it reopens (the windows + dialogs behave the same way), and the vertical budget keeps the + segoe skeleton - a locale face a couple of pixels taller than the + latin metrics paints inside the row spacing, the ltext rows sit + two pixels tight (the simulation models the budget with the + tolerance stated, not assumed away). + the version moves to 1.1.11 build 40. + +Stable: Version 1.1.10 (field fix round 6: the dialog return value) + the sixth field round repairs the 1.1.09 dark options fix itself. a + source audit of the custom draw path caught the headline bug: a dialog + procedure cannot return a notify result directly - the dialog manager + keeps the message result in the window data, so the plain + cdrf_skipdefault return handed every button a zero (= cdrf_dodefault) + instead. the skip never reached a single control on any machine: + - the custom draw result travels through dwlp_msgresult now, the way + the nm_customdraw documentation prescribes for dialog procedures: + setwindowlongptr on the dialog, then a true return. two places + changed: the shared dark proc's notify case and the notify function + it calls. + - the glyph travels with the fix: a working skip takes the whole + native painting (the official wording: the control will not draw + any portion of the item), so the checkbox and radio faces draw + complete now - the dark dialog background, the theme part glyph in + the control's own checked, mixed, disabled and hot state (bm_getcheck + plus the custom draw item state through the cbs_*/rbs_* map), the + light label and the focus frame drawn exactly once (two xor frames + cancelled each other before - the keyboard walk lost its dot in the + dark). + - the button theme opens once per dialog and closes on destroy and on + the theme change broadcast (an open and a close pair per + notification was pure uxtheme bookkeeping on every paint). + - the touch probe mask drops the pen digitizer bit: nid_integrated_pen + is 0x04 and nid_external_touch is 0x02, so the old mask missed the + external-only touch screens and passed the pen-only digitizers. + - the ci runs the real machine smoke test now: every push and every + tag build opens the full anomaly sample set through the freshly + compiled exe on the windows runner (the test existed since the + 1.0.02 audit round but never ran automatically). + - readme honesty pass: the dark options wording matches the shipped + mechanism, the emf/wmf bullet notes the metafiles rasterize through + gdi+ (display-level support, not a native loader), and the pan && + scan removal lands in the readme story (it was recorded in the + 1.1.0-beta.6 changes entry only - the removal was deliberate: the + feature stretched x and y independently and fought the aspect ratio + lock). + the version moves to 1.1.10 build 39. + +Stable: Version 1.1.09 (field fix round 5) + the fifth field round lands the dark options text reports. this + entry replaces the withdrawn first 1.1.09 build (build 37): that + build flipped the checkboxes and the radios to owner draw on every + machine, the owner draw bit occupies the button type field, so the + flip replaced BS_AUTOCHECKBOX itself - the automatic check state + machine went with it, clicks stopped toggling, BM_GETCHECK read + zero and every options checkbox froze in the dark ui: + - the checkbox and radio labels paint through the custom draw path + now: the themed button paints its own label color (the + WM_CTLCOLORSTATIC text never reaches it - the field report read + black labels at 0.78:1 on the dark face, the microsoft q&a + documents the behavior), so the shared dialog dark proc takes the + button NM_CUSTOMDRAW notifications and repaints the label only - + light text, the control font, the focus frame - returning skip + default, which on a button replaces the label drawing while the + system theme keeps painting the glyph with its checked, hot and + disabled states. no style bit changes: the check state machine, the + radio grouping and every saved-settings read keep working in both + themes. the dead owner draw flip is gone entirely (it also sat + latent on the pre 1903 fallback since the last round). + - the fonts read different between the light and the dark ui: the + owner drawn controls drew with whatever font the draw dc carried, + and the eleven dialog templates mixed two MS Shell Dlg charsets + plus the obsolete DS_FIXEDSYS flag (the pages and the containers + measured their dialog units with different fonts). every template + now declares the same statement - Segoe UI 9pt, one weight, one + charset - so the pages and the containers share one unit grid and + the drawn text selects the control font explicitly before it draws + (the pick and the restore ride every owner draw path). + - the about dialog carried the last light strip in the dark ui: the + bottom band painted the system button colors unconditionally. the + band follows the theme now (the dark chrome strip with its divider + lines) and the light ui takes the fixed win11 command bar palette + (the white face, the subtle line) instead of the system-dependent + button colors. + - the geometry checks move to the pixel grid: the dialog units + follow the dialog font, so a font change rescales every template + 15-23 percent while the DLU numbers stay put - the new simulation + walks every control of every template on the Segoe UI 9pt base + units and proves the fit (containment, the eleven association + checkboxes, the label-plus-glyph widths). + - the option inventory stays pinned: the test baseline carries + every control id of the eleven dialogs (89 ids) and the rewrite + loses none of them. +Stable: Version 1.1.08 (field fix round 4) + the fourth field round lands the reports from the 1.1.07 test: + - the light dialogs painted dark controls: the dark theme classes + were applied whatever the app theme, so the light options page + showed black comboboxes and black select-all buttons. the classes, + the immersive flag and the owner draw flips now follow the app + theme together, and the flip back to light restores the explorer + class and the light title bar (an open dialog no longer keeps the + dark chrome from an earlier flip either). + - the dark combos grew a chin: the owner draw flip rebuilt the + closed field height from the font metrics, which drifts a few + pixels at some dpis - the field then grows or shrinks against its + label row. the flip now captures the native field height first and + keeps it exactly, so the dark combo is pixel identical to the light + one (the measure fallback reads the captured height back). + - the dark push buttons owner draw on every build: the native dark + button carries a light bottom edge (the chin under the buttons) and + a hard rectangle that fights the rest of the dark chrome. the flat + face matches the combo fields exactly; the bitmap color swatches + keep their own painting in every state. + - changing the backdrop or the canvas color with no image open + showed a load failure at the bottom left: the refresh reloads the + current file, and with none the empty name only fails. the refresh + now keeps the blank state - no reload, no error, the stale flags + reset - so the bare program accepts any color change quietly. + - the mat confusion: the backdrop is what shows under the + transparent pixels of an image with alpha, not the canvas around + the image. the menu is renamed to the transparency backdrop and a + new view menu item (windowed background color...) puts the canvas + color one click away from it. the zoom range note: the below-fit + ladder from the 1.1.06 field round reaches about fit/16 - the 3 + percent floor and the 1600 percent cap are the two ends of that + symmetric range. + - the theme change broadcast schedules the one shot dark re-check + as well (the visual style flip can race the registry the same way + the immersive color set broadcast does). + the version moves to 1.1.08 build 36. + +Stable: Version 1.1.07 (the second-rework simulation round) + the second rework check runs as a simulation: the new suite + (tests/simulation_test.py) extracts the constants, the formulas + and the control flow from the shipped source and re-executes the + behavior itself - a renamed symbol or a reordered source keeps a + string guard honest only by luck, so every field report is replayed + against the extracted logic: + - the mat color battery walks light, dark, cutoff-boundary and + saturated colors through the extracted 601 mapper: the light mats + land at or under the chrome face with the hue intact, the dark ones + pass through, and the white fast path is bit-exact with the scaled + formula. both user states from the report (the empty canvas and the + open-image backdrop) prove they route through the one shared mapper, + and the follow mat proves it picks the color of the mode the window + actually paints. + - the mru model replays a five-open burst (zero ini writes land + mid-burst on the ui thread, exactly one deferred write after the + settle, and the exit fold absorbs a still-pending write), fifteen + opens against the ten-entry cap (newest first, the oldest evicted), + the case-variant reopen (the move keeps the stored casing and a + top-row variant stays put), a twenty-row hand-edited ini (the load + walk stops at the cap and the clamp repairs the count), and the + surgical popup swap (no SetMenu, one row touched, the swapped-out + popup destroyed). + - the menu walk locates the command-table loop body span and proves + the mru insertion sits after the loop closes: the round-42 bug would + emit one recent row per command, and the simulation emits one. + - the zoom ladder walks the extracted 278-step shrink range: the + 200% fill lock is gone, the floor lands about one sixteenth of the + fit and mirrors the 16x native cap, every negative position reads a + positive table entry (never out of bounds), a runaway position + clamps to the floor and the deepest render keeps its one pixel. + - the blank state replays a missing-file open, a close and a later + failure: the status reports are fresh, never stale and never sticky. + - the options geometry parses the resource script and proves all + eleven association checkboxes sit inside the 242-tall page, the page + fits the 264-tall tab and the buttons keep the five-unit margin. + - the theme flip replays the registry race: the broadcast that + outruns the personalize write applies nothing at t=0, the 400ms + re-check lands the flip, and every flip invalidates the whole + window unconditionally. + - the release identity: the version quad moves to 1.1.7.35 and the + tag, the installer, the about dialog and the readme all carry + 1.1.07. the ci runs the simulation suite beside the two existing + suites on every push and on every tag. +Stable: Version 1.1.06 (field fix round 3) + the field report read "the background mat color is dead, with an + image open and without one": a customized windowed background color + always won, so a light mat kept glaring out of the dark chrome in + both states while the default white had long mapped to the dark + canvas. the mat rule is shared now: in the dark ui any light color + (601 luminance at or above 48) keeps its hue but lands at or under + the dark chrome face, the default white stays bit-exact with the + palette canvas, and an already dark color passes through unchanged; + the light ui always shows the exact configured color. the custom + backdrop color follows the same rule (a light backdrop under + transparent pixels used to glare the same way), and the follow + backdrop now matches the mat the window actually paints - the + fullscreen canvas shows the fullscreen color under the image instead + of the windowed one (a two-tone split around fullscreen pictures). + changing the windowed color from the options dialog re-tints the + windows 11 caption, repaints the canvas and reloads the image, so a + follow-mode transparency picks the new mat up immediately (the ok + button used to invalidate the canvas only, which left the caption + tint and the under-image backdrop stale until the next theme flip). + dark dialogs: the options pages (and every dark dialog) owner draw + their comboboxes on every windows build now - the darkmode explorer + style carries no combobox parts, so the language, dark-mode, + blit-mode and action fields stayed light inside the dark pages on + 1903+ machines. the comboboxes take the darkmode common-dialog + theme class for the dark frames and arrows where it exists, and the + field and list rows paint through the dialog dark handler on every + build. + docs: the readme told the 1.0.04 story while the shipped version was + 1.1.06 - the what's new section carries the 1.1 line (emf and wmf, + recent files, the backdrop menu, the dark dialog completion, the + below-fit zoom ladder and the field fixes), the format list carries + emf and wmf, and new sections document the canvas/backdrop/dark + rules and the recent-files behavior. the test suite pins build 34 + and gains the round-44 guards (the mat mapper math, the backdrop + rules, the fullscreen-aware follow, the options ok chain, the + combobox owner-draw ungating and the cfd theme wiring). + +Stable: Version 1.1.06 (field fix round 2) + open speed: every single-file open wrote the whole settings file and + rebuilt the entire menu bar on the ui thread before the image load was + dispatched - the visible stutter when opening files (worst with + real-time antivirus scanning the temp ini). the recent-files save is + debounced now: a two second timer coalesces a burst of opens into one + write, and the exit / logoff saves fold a still-pending write in. the + menu update swaps just the recent-files popup inside the live file menu + instead of destroying and recreating the whole bar (the full-rebuild + path is deleted outright), so the dark bar owner-draw state survives + without a re-apply and the non-client area is not repainted mid-open. + recent files count limit: the list is capped at ten entries on every + path - a compile-time check locks the command-id block to the array + bound, the ini load clamps the count, the push trims with a while loop, + and the popup builder clamps its own loop bound, so the list can never + emit command ids past the reserved block or overflow the menu. + options dialog: the emf and wmf association checkboxes pushed the + association list past the general page template bottom (the last rows + were clipped). the page grows to fit all eleven checkboxes and the + group box, and the options container, tree, tabs and buttons move down + with it so the layout relationships survive. + +Stable: Version 1.1.06 (field fix round) + the field report on the 1.1.06 build: the recent-files submenu was + inserted once per command-table entry instead of once per rebuild, so + the file menu grew dozens of duplicate rows (the block moved outside + the walk, and the test suite now simulates the brace depth so the + placement can never regress silently). + status honesty: closing the image kept the "failed to load" and "file + not found" messages on the status bar with no image open - the blank + state clears both flags now. + theme stability: every dark-mode flip repaints the whole window (a + partial invalidation left a light strip beside the toolbar and a + white canvas until a manual resize), and the immersive color set + broadcast gets a delayed re-check so a registry value that settles + after the message still lands. + chrome symmetry: the light toolbar strip follows the light menu face + with flat separator lines instead of the gray button face with the 3d + etch, so both themes read as one chrome band above the canvas. + options dialog: the page-title tab header and the sliver under every + page stayed light in the dark ui (the comctl tab paints its whole face + itself and the custom draw only reached the items) - the subclass + paints the entire control dark now. + zoom range: the ladder extends below the best fit (about one + sixteenth of it, mirroring the 16x native cap above) so a touch + pinch can zoom out to a thumbnail view; the fill-window upscale no + longer locks small images at a 200% minimum. the allow-shrinking + option keeps its meaning: with shrinking off the best fit stays the + floor. + +Stable: Version 1.1.06 (modern ux round) + third audit round: the fork now answers every low-cost item from + the upstream wish list it can carry. emf and wmf files open + everywhere (the gdi+ draw path rasterizes metafiles with no new + decoder, the association table, the open dialog filter, the + everything search default and the command line switches all grow + the two extensions), the status bar picks b / kb / mb / gb units + instead of rounding every file to kilobytes, the file menu gains + a persistent recent-files submenu, and the edit command gets a + default shortcut and menu hint again. + audit consistency: the webp frame-delay allocation multiplies + through the safe size helpers (the one bare multiply left in the + newest code), and 32-bit builds cap animated webp canvases at 25 + megapixels (the decode canvas, the anim decoder frame and the + display bitmap are roughly 12 bytes per pixel inside a 2 gb + address space). + ux hardening: the wallpaper change asks before it touches the + desktop (the menu comment has wanted this dialog since the first + release and the ctrl+d default key returns with it), up and down + navigate when no slideshow is running, the single o key for + options becomes ctrl+comma so a stray letter no longer pops a + modal dialog, and everything-add moves to ctrl+alt+e so the + editor can take ctrl+shift+e. + +Stable: Version 1.1.05 (second review fix round) + second review: the thirteen findings from the first audit round were + re-verified line by line against the sources and msdn. two were + withdrawn (the mem debug tail magic sits fully inside the allocation + and the two-step getregiondata is the documented pattern), the + small-pool alignment note was downgraded to a comment fix, and the + confirmed set ships here. + drag and drop: every wm_dropfiles now ends in dragfinish - the shell + file list leaked on every drop. the clipboard file-list paste reuses + the same handler without finishing the clipboards own hdrop (which + would corrupt clipboard memory). + memory safety: a null free crashed inside heapsize before the invalid + free guard could run; the glyph cache eviction copied overlapping + arrays with memcpy; the clipboard dib paste now applies the same + pixel budget as the file loaders and no longer truncates the copy + size to int (os_copy_memory and os_move_memory take size_t lengths). + registry: the add/remove programs entry is written to the 64-bit view + and removed with regdeletekeyexw (regdeletekeyw cannot reach the + alternate view; the nsis probe already used setregview 64), with the + legacy wow6432node copy swept on uninstall. + webp animations: each frame now carries its own duration from a + container scan - the old loop handed every frame the gap to the + previous one and the last frames duration never existed. + touch: the digitizer probe asks for a touch screen (not just any ready + digitizer), gid_begin and gid_end reach defwindowproc as msdn requires, + and the press-and-hold and flick system gestures are disabled for the + window. + robustness: the ini reader refuses files over 16 mb, a failed utf-8 + config conversion no longer reads an unterminated buffer, bad + localization ids clamp to a fallback instead of an out-of-bounds read + in release builds, and the safe_size wchar multiply comment no longer + says addition. + +Stable: Version 1.1.04 (tag hygiene round) + tag hygiene: the public tag list consolidates to the release ladder + 1.1.02, 1.1.03, 1.1.04 - the dashboard round markers and the + 1.0.03/1.0.04 pair leave the tag namespace after this release + ships (the round history stays reachable through the backup ref + and the archive snapshots, and the 1.0.x release pages keep + their assets), so the tags view reads as one clean version + staircase with this release on top instead of a dashboard + marker sitting above the releases. + shipping code: unchanged from 1.1.03 apart from the version + identity - the magnifier pill, the capsule zoom bar, the 32bpp + toolbar icons and the dark menu strip from the pill round ship + again as they are. + version order: the ladder stays strictly increasing, no + duplicates: it now reads 1.1.02, 1.1.03, 1.1.04. + +Stable: Version 1.1.03 (magnifier pill round) + pill icons: the zoom magnifier glyphs are redrawn. the zoom in/out + strokes declared three point polylines over two element arrays, so the + renderer walked one element past each array and drew a stray tail line + to whatever coordinate pair lived in the adjacent memory (the crooked + cross and handle in the field screenshots), the hand written 21 point + ring wobbled between radii 12.65 and 13.6 which read as a lumpy lens at + the pill sizes, and the cross strokes collapsed into capped smudges at + the small toolbar sizes. the ring is now a true gdi+ ellipse primitive + (drawn through gdipdrawellipse, not a sampled polyline), the counts + match the arrays, the handle starts exactly on the 45 degree ring + point, and the cross grew one grid unit longer and one wider. + pill shape: the zoom buttons and their tray are true stadium capsules + now (roundrect with half height end radii) with breathing room between + the buttons - the old zero gap layout packed both square borders back + to back in the middle (a double line) and the blocky pair sat next to + the flat toolbar like a patch from another toolkit. the glyph padding + follows the button height so all four sides stay even at every dpi. + toolbar icons: the toolbar image list keeps the 32bpp alpha channel + (ilc_color32) - the old 24 bit list with a mask binarized the + antialiased glyph edges and washed the toolbar icons into a pale gray + while the zoom pill drew the same glyphs from the raw icons at full + contrast (the two-tone toolbar the field screenshots caught). + dark strip: the rebar strip behind the centered toolbar now carries + the dark chrome face - the rebar window was registered with the light + window class brush, so the slabs on both sides of the toolbar stayed + white in dark mode (the big white rectangle the field screenshots + caught in the menu bar row). + version order: the release series returns to the 1.1 line as the + leading one, so the tag ladder reads 1.0.03, 1.0.04, 1.1.02, 1.1.03 - + strictly increasing, no duplicates, nothing deleted. + +Stable: Version 1.0.04 (pointer width budget) + load performance: the pixel budget ceiling is now pointer width + dependent. 32-bit builds keep the 100 mp guard (a 100 mp rgba + frame is already 400 mb against a 2 gb address space) while + 64-bit builds (x64 and arm64) raise the ceiling to 400 mp, so + real panoramic stitches and large flatbed scans load normally + instead of failing like a corrupt file - the reported 1.0.03 + regression where big-but-honest images stopped opening. + budget diagnostics: both loaders now print the refusal reason + (the claimed megapixels and the ceiling) through the debug + channel, so a user wondering why a file fails can turn the debug + banner on and read it - silent refusals are over. + test kit: the anomaly sample set grows to 38 samples - 35 now + doubles as the x64 acceptance boundary (110 mp loads on x64, + still refused on 32-bit) and 38 pins the x64 refusal point + (625 mp lying header). the guard suite pins both branches of + the ceiling split and the diagnostic on both loaders. +Stable: Version 1.0.03 (version display unification) + version identity: every user visible version now shows the release + identity - the tag string. the about dialog showed 1.0.2.25, the + add/remove programs entry showed 1.0.2 and the installer version + keys showed 1.0.02.x64 while the tag said 1.0.02 - the about line, + the uninstall DisplayVersion, the debug banner and the two nsis + version keys now derive straight from VERSION_STRING, and the test + suite guards all five display points against regression. + +Stable: Version 1.0.02 (third audit round closed) + pixel budget: both decoders (gdi+ and webp, animation and + still) now refuse a canvas over 100 mp before any allocation + happens - a 428 kb hostile header asking for a 20000 x 20000 + decode used to reach the allocator and die with a fatal + dialog; it now fails like any unloadable file. + uninstaller identity: closing the old instance no longer trusts + the window class name alone - the process image name is + verified as voidImageViewer.exe before any close or terminate + is sent, so a foreign program reusing the class name is left + alone. + third audit delivery: a generated anomaly sample set (37 + samples across truncation, lying headers, zero delay, frame + floods, broken chunk order, trailing garbage and over budget + canvases) plus a windows smoke test script, so a passing + suite can be followed by a real machine run. + +Stable: Version 1.0.01 (the fork restarts its version line at a clean 1.0.01) + version line: the public version sequence restarts here. the retired + 1.1.x line (three stables, seven release candidates, thirteen betas) + is gone from the tags and the releases; this file now keeps one entry + per development stage instead of one entry per round - the full + per-commit story lives in the git log. no code change ships with the + reset: the binaries are the twice-audited tree with the version + resource moved to the new line. + + the fork, by stage: + - foundation betas: the touch and zoom core (pinch, pan, two finger + and double tap, the floating zoom bar, one percent zoom steps), the + bilingual installer, the ui language switcher, save as, dark mode + detection, the single instance fix. + - engineering release candidates: the modern chrome and the release + engineering - PerMonitorV2 dpi, win11 rounded corners, the vector + toolbar glyphs, the fullscreen overlay fade, pinned ci runners, the + four stage release pipeline, the single source version.h, the pinch + floor and the 1600 percent zoom ceiling. + - dark completion: the complete dark ui - dialogs, status bar, + toolbar, zoom bar, the owner drawn menu bar (for the builds that + never darken a win32 menu bar), the options tabs, the pre 1903 + control fallbacks, live re-theming, crisp glyphs. + - audit hardening: two full codebase user audits - the gdi+ frame + delay and frame dimension guards, safe size wiring at every + allocation arithmetic, the dark brush and shuffle array releases, + the save as extension reservation, both performance counter seed + halves. + +Monday, 12 January 2026: Version 1.0.0.15 + fixed an issue with scrolling large images. + improved position offset when using numpad keys. + +Tuesday, 16 December 2025: Version 1.0.0.14 + fixed an issue with webp using the wrong background color. + fixed an issue with tracking the center of the image when resizing. + fixed an issue with rendering images larger than 65536x65536. + fixed an issue with screen saver not being prevented in slide show mode or when there is an animation. + improved rendering performance. + improved zooming of small images when going fullscreen. + move window action will now scroll if zoomed. + re-enabled WEBP_MSC_SSE41 + added title_bar_format ini setting. + added System.Photo.Orientation support. + added -

+What's new +-------- +**1.1.12 — the remake arc: the full GUI remake, the platform guardrails, the field fixes and the review absorption (the current stable):** +- **The stable promotion carries no code** — every fix already shipped as 1.1.12-rc.17 and passed the full gate on real Windows (the three suites, both compile legs, the anomaly-sweep smoke test, the release build itself). The stable mark is the verdict on the whole rc arc, not a new behavior. +- **The arc in one breath** — the GUI remake (the theme token system, the owner-drawn menus, the remade settings window and message boxes, the client-side top bar, the self-drawn zoom row), the structure split (the 2,208-line window procedure became 42 per-message handlers across the domain modules), the crash the remake planted and the smoke sweep caught (the status panes route by the control id first), the platform guardrails (the official manifest GUID, the UnicoWS clean, the WM_DPICHANGED lParam guard), the field arcs (the non-Win11 fallbacks, the zoom pane editor, the recent-list intent policy, the text proportions at 4K 225%, the capture-hint bridge, the menu process check), and the external review absorption (the itemID carrier, the token strip, the settings DPI correction, the resize escape hatch, the startup DPI sync). +- **The discipline that earned the mark** — seventeen release candidates, each landed changelog-first, each pinned by its own guard section, each version-guarded, each green on the CI legs before its tag; the anomaly sweep opens real images on a real Windows runner for every tag. +- Full narrative: `Changes.txt`. -void Image Viewer main window: +**1.1.12-rc.17 — the review absorption round (the previous release candidate):** -![Void Image Viewer Image View](https://www.voidtools.com/voidImageViewer.Image.View10.gif) -


+- **The external carpet review (v2) absorbed** — its confirmed findings fixed, its refutations recorded. The gesture "leak" it asked to self-check is not there (every unhandled WM_GESTURE path forwards to DefWindowProc, which owns the info handle), and the strip-height audit found every view geometry in the tree riding the one `_viv_get_view_top()` helper. +- **The status pane index rides the official carrier** — the draw read `itemData` (the lParam our own SB_SETTEXTW happens to store there); it now reads `itemID` (the field comctl officially fills with the pane index), itemData stays the fallback — and an unresolvable pane paints the strip face instead of returning silently unhandled, closing the rc.11 bottom-white-bar failure mode for good. +- **The status strip joins the token system** — the erase, the pane fill and text, the size grip fill and dots, and the zoom editor field all rode hardcoded RGB values while the menubar and toolbar ride the chrome token. Every site routes through the theme tokens now, so a theme or accent flip re-skins the strip too, and the three strips read as one chrome. +- **The settings window DPI correction + the escape hatch** — the outer frame is re-measured at the window's own DPI after the create (the same correction WM_DPICHANGED applies after a move; the probe recorded the mismatch but never fixed it), and the window can now be enlarged from the left/right/bottom edges (minimum track size = the design size) so a page whose content outgrows the fixed panel can never trap its footer out of reach. +- **The startup DPI sync** — GetDC(0) reads the primary monitor; one explicit `os_window_update_dpi` after the main window exists, before the first strip is built from the globals, so a launch restored onto another monitor builds every strip at the right scale. +- **Deferred on purpose (the review's own advice)** — the retired options dialog stays frozen until the settings window regains list browsing; the per-window DPI refactor and the resource.h ID splits stay on the debt list. +- Full narrative: `Changes.txt`. + +**1.1.12-rc.16 — the open intent round (the previous release candidate):** + +- **The recent-list trade refunded** — the last round's guard asked "is this the file already on screen" for *every* open, which cost the standard MRU behavior: clicking the recent entry of the displayed file stopped re-topping it. The intent is now declared where it is knowable instead of guessed where it is not: the open dialog, the drag-drop and the recent click feed the recent list unconditionally (re-opening the displayed file re-tops it, like every other Windows MRU). Only the one path that cannot know its own intent — the single-instance forward of a second launch, the re-entry the rotate verb's refresh and the rotate-then-recheck double-click ride — keeps the same-file question: a same-file forward is a reload, not a recent open. A forwarded new file still enters the list. +- Full narrative: `Changes.txt`. + +**1.1.12-rc.15 — the field report round (the previous release candidate):** + +- **Rotating an image landed it wrongly in the recent files list** — the rotate itself never touches the list; what reordered it was a silent re-open (any path handing the viewer the file already on screen fed the list as a brand-new open). The push site now asks one question: is this the file already on screen? A reload is not a recent open. Deleting and renaming also maintain their own entry now — the delete drops it, the rename swaps it in place. +- **The text proportions at 4K 225%** — the settings window was the one surface riding its own font size (13 dip rows) while the menu bar, toolbar, message boxes and dialogs all sit on the system font — an invisible 1px gap at 96 dpi that becomes 2-3px on every glyph at 216 dpi. The settings rows move to 12 dip, the descriptions to 11, and the status bar now carries the menu font explicitly (re-pinned on DPI change). +- **The garbled line under the shortcuts buttons** — the capture hint ("edit keyboard shortcut: ...") copied the localization string through the wide-string copier while localization returns UTF-8, so every byte pair became a mojibake character. The copy goes through the UTF-8 bridge now, and a tree-wide guard keeps the pattern from coming back. +- **Menu theming hardened** — the system menu window is found by a class name shared by every menu in every process; the find now checks the owning process before theming, so the viewer never paints a stranger's menu and leaves its own plain. +- Full narrative: `Changes.txt`. + +**1.1.12-rc.14 — the zoom pane editor round (the previous release candidate):** + +- **The corner zoom percent needed two clicks, and showed a "select box"** — the click never reached the pane: the pane doubled as the window-drag anchor (inherited from upstream), its subclass ate the button down and the move loop ate the up, so the open command only fired from an inactive window's orphan up. The pane is pure input now — the drag lives on the toolbar, the menu gaps and the title bar. +- **The editor is in place, not in a 1998 box** — the pane itself becomes a borderless number field in the strip's own font and colors; enter commits, escape cancels, focus lost commits, typing replaces the selected digits. The centered dialog (sunken field, native buttons, select-all blue block) is retired along with its template and strings. The system selection color stays — the edit control offers no custom one, and it lives on four digits for the seconds the editor is open. +- Full narrative: `Changes.txt`. + +**1.1.12-rc.13 — the non-win11 field round (the previous release candidate):** + +- **The play button showed “pause” on an idle photo** — the toolbar read the animation preference bit as the playing state (it defaults to on and every image switch resets it); the face now gates on the frame count, and every clock-changing path notifies the toolbar and recomputes the on-top window. +- **“Zoom needs two clicks to work”** — the first zoom-in from a fresh best fit snapped the wrong way (31% → 30, invisible) and a zoom-out from best fit hit a dead gate written before the below-fit ladder. Stepping is direction-strict now, the floor gate reads the true ladder floor, and a sparse-zone fallback guarantees a move. +- **The non-Win11 look** — the settings window gets a real drop shadow on Windows 10/7, its dropdowns ride the same owner-drawn rows as the menus (no more system-blue lists next to the accent pills), the light hover/nav/strip tokens recalibrate for real contrast and layering, and the message box buttons take the pill radius. The DWM chrome calls double as the platform probe, so every fallback is one honest check. +- Full narrative: `Changes.txt`. + +**1.1.12-rc.12 — the platform guardrails round (the previous release candidate):** + +- **The Windows 8.1 manifest GUID was corrupted** — the supportedOS id for 8.1 was a hand-mangled value, so Windows 8.1 hosts never matched their own entry; the manifest now carries the official GUID (verified against the Microsoft application-manifests documentation). +- **The dead UnicoWS dependency is gone** — the Win32 link lines carried `UnicoWS.lib` (the Windows 9x unicode layer) straight from the original upstream import; nothing in the code imports an MSLU symbol and the x64 builds never carried it. Modern SDKs are phasing the stub out, so its removal is the forward-compatibility clean — the CI legs still link today. +- **`WM_DPICHANGED` no longer dereferences a null rect** — the system always supplies the suggested rectangle, but synthetic messages and compatibility layers may not; the resize is now optional while the DPI refresh still runs. +- Full narrative: `Changes.txt`. +**1.1.12-rc.11 — the carpet repair round (the previous release candidate):** + +- **The remake's two headline breaks are fixed** — the menu bar roots measured empty since the rc.9 owner-draw flip (the labels now re-derive from the live rows, Alt mnemonics with them), and the status date pane rendered a lone "0" (a wide format through the narrow parser; the stamp now uses the localized system formatters). +- **The image viewport caught up with the top strips** — the toolbar moved under the menu bar in rc.8 but the image math still reserved its band above the status bar: a 40dip dead strip and the image top hidden behind the chrome. One view-top origin now rides every size, blit, mouse anchor and the zoom pill. +- **The theme flip flushes the token cache** — the half-skinned UI after a system theme change is gone; the toolbar rides the same tokens as the menus (light hover is the quiet 3D-light, no more selection blue); the message boxes are owned, leak-free and close-correct; the shortcut editor keeps a no-op confirm a no-op; **Win 7 closes the DPI ladder** (legacy `dpiAware` + runtime `SetProcessDPIAware` — it was DPI-*unaware*, not system-aware); the pill percent matches the status bar; the play button stops forcing fullscreen. +- Full narrative: `Changes.txt`. + +**1.1.12-rc.10 — the dpi correctness round (the previous release candidate):** +- **The high-dpi font bug is fixed at the root** — the per-monitor-v2 declaration never reached the binary the way it was read: the zig builds shipped no manifest at all, and the `os_init` runtime safety net sat *before* its own `GetProcAddress` block, so the pointers were still null when it ran and it silently never fired. A dpi-unaware process gets bitmap-stretched by the system at high dpi — every font blurry and oversized. The claim now runs after the api probes and stacks three independent, all-guarded layers: a process-wide claim (Win10 1703+ `SetProcessDpiAwarenessContext`), a per-thread claim (1607+), and the Win 8.1 `shcore` fallback (Win 7 keeps the classic system-aware behavior); the zig build also drops a `viv.exe.manifest` next to the exe for loader-level coverage. +- **The message box scales from its parent's monitor** (not the stale global logical dpi) — correct on mixed-dpi monitor pairs. +- **17 splice-accident double-brace wrappers with dead `DefWindowProc` tails unwound** in the wndproc domain. +- Verified under wine: the pre-fix binary renders the settings window bitmap-stretched to ~2x at 150% scaling; the fixed binary renders 1:1 physical and self-scales to exactly 1.5x (660×628 → 990×942) with the fonts riding the same per-window dip pipeline. -void Image Viewer General Options: +**1.1.12-rc.9 — the gui remake round 2: one palette for everything:** -![Void Image Viewer Options General](https://www.voidtools.com/voidImageViewer.Options.General10.png) -


+- **One theme system for the whole ui** — the new `viv_theme` domain holds 17 semantic tokens × dark/light × five accents (azure, teal, violet, amber, rose). The chrome strips, the menus, the dialogs, the settings window, the zoom pill and the tooltips all resolve their colors through it, so a theme or accent flip re-skins the app with zero per surface edits. The accent ships with an ini key (`accent_color`) and a live swatch row in the settings window. +- **The popup menus are app drawn** — every visible row carries a draw record and the painters re-derive the label at draw time (command table + localization + live key bindings), so a language or shortcut change never shows a stale row. Accent check marks, right aligned shortcuts, hairline separators; the popup layer gets the win11 rounded corners and a themed border through the dwm; `WM_MENUCHAR` keeps alt+letter working. No undocumented uxtheme ordinal in the menu path anymore. +- **Themed message boxes** — `viv_msgbox` draws the vector icon, the wrapped text and the accent primary button with a real modal pump (tab/enter/esc); the five `MessageBox` call sites moved over (the fatal paths in debug/mem keep the native box on purpose). +- **The classic dialogs join the theme** — the dark dialog skin reads the same tokens (the old hardcoded palette is gone) and every dialog frame gets the win11 rounded corners plus the caption color from the dwm. The old tabbed options route opens the remade settings window. +- **A build the mockup cannot drift from** — `scripts/extract-theme.mjs` transcribes `src/viv_theme.c` into the page simulator, and zig cc builds the whole tree (`build-zig/build.sh`, 98 translation units, about 465 KB x64 with `-Os`). +**1.1.12-rc.7 — the zoom pill rework:** +- **The zoom pill is one self-drawn window** — no nested owner-drawn buttons fighting the layered tray: `zoomui.c` paints the tray and every capsule in a single `WM_PAINT` pass (true stadium caps at every DPI), hit tests the button rects itself, tracks presses with capture (no command when the drag leaves the button), and passes clicks through everything outside the capsules so a fading pill never blocks the image. -void Image Viewer View Options: +Recent versions, one line each — full per-round detail in [Changes.txt](Changes.txt): -![Void Image Viewer Options View](https://www.voidtools.com/voidImageViewer.Options.View10.png) -


+- **1.1.12-rc.6** — the top bar remake: the menu bar is a fully self-drawn child window (`viv_menubar`), the status bar owns its dark face, the toolbar button spacing is pinned uniform in both themes. +- **1.1.12-rc.5** — the structure round: the gesture cluster home in the view domain, the 2,208-line window procedure split into 42 per-message handlers in the new `viv_wndproc.c`, the splice guard's file manifest pinned. +- **1.1.12-rc.4** — the white band after opening Options or switching the theme fixed at the root (the dark re-apply lost its flip gate; the sweep is now unconditional and idempotent); the Options navigation tree reads in the dark UI. +- **1.1.12-rc.3** — the monolith is gone: `viv.c` (21,129 lines) is now a 4,718-line core plus eleven domain modules and a `viv_state.h` shared-context layer — a pure physical move (function bodies byte-identical; `/GL` whole-program optimization keeps cross-module inlining, performance unchanged); the setup offers the EMF/WMF associations; the vendored libwebp pruned of non-Windows build systems, fuzzers and docs (62 files — `COPYING`/`PATENTS`/`AUTHORS` kept). +- **1.1.12-rc.2** — the About dialog's band and title move into the resource template (correct at every DPI and in both themes); the post-theme-flip white band fixed (the frame repaint joined the sweep, the toolbar strip relayouts with the system metrics). +- **1.1.11** — one type system for the whole UI (the system message font per dialog at its own window DPI — CJK-safe, no more fallback-font mismatch); EMF/WMF in every association surface (metafiles rasterize via GDI+ — display-level support); recent files, transparency backdrop, complete dark dialogs. +Touch & zoom controls +-------- + +| Gesture / control | Action | +| --- | --- | +| Two finger pinch | Zoom in / out (anchored at finger center) | +| Two finger drag | Pan / scroll image (with inertia) | +| Two finger tap | Reset zoom | +| Double tap (touch) | Toggle 1:1 / best fit | +| Toolbar zoom buttons | Zoom in / out | +| Floating zoom bar | Windowed: zoom pill.

Single-finger input stays mouse-compatible, so configured click actions are unaffected. Toggle the floating controls via **View → Zoom Controls**. A pinch keeps shrinking below the windowed fit, down to about fit/16 (mirroring the 16× zoom cap) — `Allow shrinking` in Options keeps its meaning. + +Canvas, backdrop & dark mode +-------- + +- **Windowed / fullscreen background color** — Options → View, or the View menu picker; the mat around the image and the empty-window canvas. +- **Backdrop under transparency** — View → Transparency backdrop: follow the window background color, black, white, custom color, or checkerboard. Alpha images (PNG/GIF/WEBP) composite over it at load time. This is *not* the canvas around the image — that color is the windowed background above. +- **Dark UI rule** — the light UI always shows your exact colors. In the dark UI a light mat keeps its hue but drops into the dark range (the default white maps to the dark palette canvas), and the same rule applies to the custom backdrop, so nothing glares out of the dark chrome. The Win11 caption tint follows the mat. +- **The dark UI is complete** — dialogs, options pages, the menu bar and the navigation tree all follow the theme (owner-drawn where the theme API falls short on older builds); light dialogs stay light. +- Dark mode itself: Options → General → Dark mode — light, dark, or follow Windows. Theme flips repaint the whole window and re-assert the dark chrome unconditionally (a delayed re-check heals any system-side light repaint), and the open dialogs re-theme live. + +Recent files +-------- +File → Recent keeps the last ten opened paths (deduplicated case-insensitively; missing files drop out on the next open; Clear empties the list). The list is capped at ten on every path and writes are debounced off the open path. + +Languages +-------- +English and 简体中文 ship built-in. +- The setup picks the language on its first page. +- **Options → General → Language** switches Auto / English / 简体中文 on the fly (no restart). +- Stored as `language=auto|english|chinese` in `voidImageViewer.ini`; unattended installs may pass `/language english|chinese|auto`. -void Image Viewer Controls Options: +Build from source +-------- +Plain C + Win32 API, Visual Studio: -![Void Image Viewer Image Controls](https://www.voidtools.com/voidImageViewer.Options.Controls10.png) -


+1. Open `vs2019/voidImageViewer.sln` (VS2022+, v143 toolset) or `vs2026/voidImageViewer.sln` (v145 toolset). Both share one file list (`voidImageViewer.files.props`). VS2019 works with `/p:PlatformToolset=v142` (not CI-covered). +2. Build the `voidImageViewer` project (x64 or Win32). +3. Optional setup: NSIS 3 via `nsis\build_installer.ps1` (auto-detects the VS version; sources compile with `/utf-8`). +The zig cross build needs no Visual Studio: `sh build-zig/build.sh` (98 translation units, about 465 KB x64 with `-Os`). The vs linker embeds `res/voidImageViewer.Manifest` (per-monitor v2); the zig build keeps no embedded manifest, so it writes `viv.exe.manifest` next to the exe and the runtime claim in `os_init` covers even a stripped copy — keep the two files together, or build through vs when you need a single-file binary. +The source layout: one core (`src/viv.c` — the window procedure, startup, the command line, the state definitions) plus eleven domain modules (`src/viv_.c/.h`) and the shared-context header (`src/viv_state.h`);

括号平衡、引用解析、单一编译单元定义四道本地验证 + CI 双工具链编译。 +2. **域合并与新增**（对 spec §4 片序表的落地修正）：fullscreen 并入 + chrome；dialog_dark 基础设施独立为 dark；everything 并入 playlist； + **新增 install**（安装/关联/注册表/快捷方式——spec 把它们留在残余， + 实测 975

导出函数同理：283 个函数中 163 个导出，其余保持 static。 +4. **性能与体积保证**：工程早已开启 `/GL`（WholeProgramOptimization， + 链接期全程序优化）——跨编译单元内联由链接器恢复，拆分零性能损失； + 导出符号不进入发行版二进制（符号只在 PDB），exe 体积不变。CI 构建 + 产物与上一 tag 对账。 +5.

merge 上游的成本； +- C 编译器对单编译单元的静态检查最严（跨文件调用必须走头文件声明，反而丢失隐式一致性）； +- 每轮 bug 修复（R63–R67）虽都在 viv.c，但都修完了——现状"能工作"。 + +**正方（拆）**： +- 教训的实质是"单轮变更量失控"，不是"文件应该大"——fluent 是**重写行为**，本方案是**纯物理移动**（函数体逐字节不变），风险模型完全不同； +- fork 与上游已深度分叉（b41/b42/rc.1/rc.2 + 回滚史），"保持上游形状"的收益已趋零——上游 merge 本就不现实； +- 守卫测试按 `viv.count(...)` 形态匹配巨型文件，域越混守卫越写不准（R64/R67 守卫演进已在挣扎）； +- 21k 行里任何导航/评审/冲突面都在放大后续每一轮的边际成本。 + +**裁决：拆**，但以"纯移动 + 状态层先行 + 域封闭性升序"把 fluent 式风险（行为重写）从物理上排除。 + +### 2.2 按什么维度拆 + +- **方案 A（按技术层级：ui/render/core）**：违反 writing-plans 的"按职责拆分，而非按技术层级"——把高内聚职责链（如 webp 动画的加载+定时器+渲染）撕碎到三层。否决。 +- **方案 B（按功能域）**：每域一起变更、一起被守卫锁定、与仓库既有模块模式（config.c/os.c/string.c 职责单一、各配 .h）一致。**采纳**。 +- **方案 C（最小拆分：只抽三巨头）**：WndProc 分发/加载线程/options 对话框。治标——viv.c 仍 ~16k 行。作为 B 的阶段产物吸收（三巨头分别落在终片/加载片/对话框片）。 + +### 2.3 共享状态怎么办（本设计的核心） + +测量事实：159 个文件级 static 被全域共享；`_viv_hwnd` 被六个候选域引用 220–238 次； +playlist 域的 6 个 static 全部被域外直接访问——**viv.c 不是"函数太长"，是"共享上下文 + 域逻辑绞合"**。 + +- **方案 A（访问器封装）**：每个搬走的 static 配 getter/setter。边界最干净，但每片引入新代码（访问器）+ 调用点改名，diff 面扩散到消费端——违背纯移动纪律，风险回归 fluent 模式。否决（域成熟后可再逐个收回，见 §4 终态）。 +- **方案 B（extern 状态层）**：159 个 static 集中为 `viv_state.h` 的 extern 声明（定义仍在 viv.c），各新域 include。C 消息驱动架构（GDI/Win32）状态天然共享，extern 是该生态的惯例（os.c 的 `os_GdiplusToken` 同模式）；每片 diff = 纯移动 + 一行 include；编译器对 extern 的类型检查完整保留。**采纳为过渡态**。 + +### 2.4 守卫兼容（拆分的隐藏成本） + +menu_structure_test.py 有 125 处 `viv.c` 引用、zoom_math 16 处、simulation 2 处。 +拆分后这些守卫若逐条改读新文件 = 巨型测试 diff 且每片重复付费。 + +**策略：read 拼接**——三套件的读取助手改为"viv.c + 所有 `src/viv_*.c` 按字典序拼接"。 +纯移动保证总文本不变 → 现有 125+16+2 处守卫**零修改自动继续全绿**， +新域文件自动纳入守卫视野。每片的测试 diff 恒为一行（首次引入拼接助手时）。 + +### 2.5 命名与目录 + +- 新模块命名 `viv_.c/.h`（`viv_recent.c`、`viv_playlist.c`……）：与既有通用模块（os/string/mem——无 viv 前缀）区分"应用域模块"层级，且杜绝与上游未来文件名冲突； +- 目录留在 `src/`（不建子目录——vs2019/vs2026/nsis 全部按 `src\*.c` 扁平约定，props 单点加行即可双工程生效，已验证两工程均 import `voidImageViewer.files.props`）。 + +## 3. 决策摘要 + +1. **片 0 = 状态层先行**：新建 `src/viv_state.h`（159 个 extern 声明，分组注释），viv.c 定义保持不动仅去 static。编译器全量验证、零行为变化。此片独立成轮，因为它本身 ~200 行 diff。 +2. **域片按封闭性升序**（测量驱动，见 §4 片序表）：状态共享越少越先拆，每片积累"域文件已存在"的势能，最后拆高耦合域时消费端已就位。 +3. **纯移动纪律**：每片只允许 ①剪切函数 ②粘贴到新 .c ③新 .h 声明导出面 ④props 加编译单元 ⑤守卫拼接自动覆盖 ⑥Changes.txt 记录移动清单。**禁止**任何函数体重写/重命名/重排序。 +4. **viv.c 终态**：残余 = `_viv_proc` 分发 + init/kill + 命令分发 + 状态定义，目标 <5,000 行（后续再评估是否拆 WndProc）。 +5. **每片门禁**：G1 三套件（拼接后自动绿）+ G2 编译零警告（CI 双工具链 windows-2022 v143 + windows-2025 v145）+ G3 push 触发 CI + G4 用户实机冒烟（拆分轮合并验收节奏：每 2–3 片一次实机，纯移动风险递减）。 +6. **回滚**：每片一个 commit，出问题 `git revert` 单片；任何时点上一 release

These -encoding schemes should make it more efficient than older formats, such as JPEG, -GIF, and PNG. It is optimized for fast image transfer over the network (for -example, for websites). The WebP format has feature parity (color profile, -metadata, animation, etc.) with other formats as well. This document describes -the structure of a WebP file. - -The WebP container (that is, the RIFF container for WebP) allows feature support -over and above the basic use case of WebP (that is, a file containing a single -image encoded as a VP8 key frame). The WebP container provides additional -support for the following: - - * Lossless Compression: An image can be losslessly compressed, using the - WebP Lossless Format. - - * Metadata: An image may have metadata stored in Exchangeable Image File - Format (Exif) or Extensible Metadata Platform (XMP) format. - - * Transparency: An image may have transparency, that is, an alpha channel. - - * Color Profile: An image may have an embedded ICC profile as described - by the [International Color Consortium][iccspec]. - - * Animation: An image may have multiple frames with pauses between them, - making it an animation. - -Terminology & Basics --------------------- - -The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", -"SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this -document are to be interpreted as described in BCP 14 [RFC 2119][] [RFC 8174][] -when, and only when, they appear in all capitals, as shown here. - -A WebP file contains either a still image (that is, an encoded matrix of pixels) -or an [animation](#animation). Optionally, it can also contain transparency -information, a color profile and metadata. We refer to the matrix of pixels as -the _canvas_ of the image. - -Bit numbering in chunk diagrams starts at `0` for the most significant bit -('MSB 0'), as described in [RFC 1166][]. - -Below are additional terms used throughout this document: - -_Reader/Writer_ - -: Code that reads WebP files is referred to as a _reader_, while code that - writes them is referred to as a _writer_. - -_uint16_ - -: A 16-bit, little-endian, unsigned integer. - -_uint24_ - -: A 24-bit, little-endian, unsigned integer. - -_uint32_ - -: A 32-bit, little-endian, unsigned integer. - -_FourCC_ - -: A four-character code (FourCC) is a _uint32_ created by concatenating four - ASCII characters in little-endian order.

The -lossless format stores and restores the pixel values exactly, including the -color values for fully transparent pixels. A universal algorithm for sequential -data compression (LZ77), prefix coding, and a color cache are used for -compression of the bulk data. Decoding speeds faster than PNG have been -demonstrated, as well as 25% denser compression than can be achieved using -today's PNG format. - -* TOC placeholder -{:toc} - -1 Introduction --------------- - -This document describes the compressed data representation of a WebP lossless -image. It is intended as a detailed reference for the WebP lossless encoder and -decoder implementation. - -In this document, we extensively use C programming language syntax to describe -the bitstream and assume the existence of a function for reading bits, -`ReadBits(n)`. The bytes are read in the natural order of the stream containing -them, and bits of each byte are read in least-significant-bit-first order. When -multiple bits are read at the same time, the integer is constructed from the -original data in the original order. The most significant bits of the returned -integer are also the most significant bits of the original data. Thus, the -statement - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -b = ReadBits(2); -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -is equivalent with the two statements below: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -b = ReadBits(1); -b |= ReadBits(1) << 1; -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -We assume that each color component, that is, alpha, red, blue, and green, is -represented using an 8-bit byte. We define the corresponding type as uint8. A -whole ARGB pixel is represented by a type called uint32, which is an unsigned -integer consisting of 32 bits. In the code showing the behavior of the -transforms, these values are codified in the following bits: alpha in bits -31..24, red in bits 23..16, green in bits 15..8, and blue in bits 7..0; however, -implementations of the format are free to use another representation internally. - -Broadly, a WebP lossless image contains header data, transform information, and -actual image data. Headers contain the width and height of the image. A WebP -lossless image can go through four different types of transforms before being -entropy encoded. The transform information in the bitstream contains the data -required to apply the respective inverse transforms. - -2 Nomenclature --------------- - -ARGB -: A pixel value consisting of alpha, red, green, and blue values. - -ARGB image -: A two-dimensional array containing ARGB pixels. - -color cache -: A small hash-addressed array to store recently used colors to be able to - recall them with shorter codes. - -color indexing image -: A one-dimensional image of colors that can be indexed using a small integer - (up to 256 within WebP lossless). - -color transform image -: A two-dimensional subresolution image containing data about correlations of - color components. - -distance mapping -: Changes LZ77 distances to have the smallest values for pixels in - two-dimensional proximity. - -entropy image -: A two-dimensional subresolution image indicating which entropy coding should - be used in a respective square in the image, that is, each pixel is a meta - prefix code. - -LZ77 -: A dictionary-based sliding window compression algorithm that either emits - symbols or describes them as sequences of past symbols. - -meta prefix code -: A small integer (up to 16 bits) that indexes an element in the meta prefix - table. - -predictor image -: A two-dimensional subresolution image indicating which spatial predictor is - used for a particular square in the image. - -prefix code -: A classic way to do entropy coding where a smaller number of bits are used - for more frequent codes. - -prefix coding -: A way to entropy code larger integers, which codes a few bits of the integer - using an entropy code and codifies the remaining bits raw. This allows for - the descriptions of the entropy codes to remain relatively small even when - the range of symbols is large. - -scan-line order -: A processing order of pixels (left to right and top to bottom), starting - from the left-hand-top pixel. Once a row is completed, continue from the - left-hand column of the next row. - -3 RIFF Header -------------- - -The beginning of the header has the RIFF container. This consists of the -following 21 bytes: - - 1. String 'RIFF'. - 2. A little-endian, 32-bit value of the chunk length, which is the whole size - of the chunk controlled by the RIFF header. Normally, this equals - the payload size (file size minus 8 bytes: 4 bytes for the 'RIFF' - identifier and 4 bytes for storing the value itself). - 3. String 'WEBP' (RIFF container name). - 4. String 'VP8L' (FourCC for lossless-encoded image data). - 5. A little-endian, 32-bit value of the number of bytes in the - lossless stream. - 6. 1-byte signature 0x2f. - -The first 28 bits of the bitstream specify the width and height of the image. -Width and height are decoded as 14-bit integers as follows: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int image_width = ReadBits(14) + 1; -int image_height = ReadBits(14) + 1; -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The 14-bit precision for image width and height limits the maximum size of a -WebP lossless image to 16384✕16384 pixels. - -The alpha_is_used bit is a hint only, and should not impact decoding. It should -be set to 0 when all alpha values are 255 in the picture, and 1 otherwise. - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int alpha_is_used = ReadBits(1); -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The version_number is a 3 bit code that must be set to 0. Any other value should -be treated as an error. - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int version_number = ReadBits(3); -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -4 Transforms ------------- - -The transforms are reversible manipulations of the image data that can reduce -the remaining symbolic entropy by modeling spatial and color correlations. They -can make the final compression more dense. - -An image can go through four types of transforms. A 1 bit indicates the -presence of a transform. Each transform is allowed to be used only once. The -transforms are used only for the main-level ARGB image; the subresolution images -(color transform image, entropy image, and predictor image) have no transforms, -not even the 0 bit indicating the end of transforms. - -Typically, an encoder would use these transforms to reduce the Shannon entropy -in the residual image. Also, the transform data can be decided based on entropy -minimization. - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -while (ReadBits(1)) { // Transform present. - // Decode transform type. - enum TransformType transform_type = ReadBits(2); - // Decode transform data. - ... -} - -// Decode actual image data (Section 5). -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -If a transform is present, then the next two bits specify the transform type. -There are four types of transforms. - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -enum TransformType { - PREDICTOR_TRANSFORM = 0, - COLOR_TRANSFORM = 1, - SUBTRACT_GREEN_TRANSFORM = 2, - COLOR_INDEXING_TRANSFORM = 3, -}; -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The transform type is followed by the transform data. Transform data contains -the information required to apply the inverse transform and depends on the -transform type. The inverse transforms are applied in the reverse order that -they are read from the bitstream, that is, last one first. - -Next, we describe the transform data for different types. - -### 4.1 Predictor Transform - -The predictor transform can be used to reduce entropy by exploiting the fact -that neighboring pixels are often correlated. In the predictor transform, the -current pixel value is predicted from the pixels already decoded (in scan-line -order) and only the residual value (actual - predicted) is encoded. The green -component of a pixel defines which of the 14 predictors is used within a -particular block of the ARGB image. The _prediction mode_ determines the type of -prediction to use. We divide the image into squares, and all the pixels in a -square use the same prediction mode. - -The first 3 bits of prediction data define the block width and height in number -of bits. - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int size_bits = ReadBits(3) + 2; -int block_width = (1 << size_bits); -int block_height = (1 << size_bits); -#define DIV_ROUND_UP(num, den) (((num) + (den) - 1) / (den)) -int transform_width = DIV_ROUND_UP(image_width, 1 << size_bits); -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The transform data contains the prediction mode for each block of the image. It -is a subresolution image where the green component of a pixel defines which of -the 14 predictors is used for all the `block_width * block_height` pixels within -a particular block of the ARGB image. This subresolution image is encoded using -the same techniques described in [Chapter 5](#image-data). - -The number of block columns, `transform_width`, is used in two-dimensional -indexing. For a pixel (x, y), one can compute the respective filter block -address by: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int block_index = (y >> size_bits) * transform_width + - (x >> size_bits); -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -There are 14 different prediction modes. In each prediction mode, the current -pixel value is predicted from one or more neighboring pixels whose values are -already known. - -We chose the neighboring pixels (TL, T, TR, and L) of the current pixel (P) as -follows: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -O O O O O O O O O O O -O O O O O O O O O O O -O O O O TL T TR O O O O -O O O O L P X X X X X -X X X X X X X X X X X -X X X X X X X X X X X -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -where TL means top-left, T means top, TR means top-right, and L means left. At -the time of predicting a value for P, all O, TL, T, TR and L pixels have already -been processed, and the P pixel and all X pixels are unknown. - -Given the preceding neighboring pixels, the different prediction modes are -defined as follows. - -| Mode | Predicted value of each channel of the current pixel | -| ------ | ------------------------------------------------------- | -| 0 | 0xff000000 (represents solid black color in ARGB) | -| 1 | L | -| 2 | T | -| 3 | TR | -| 4 | TL | -| 5 | Average2(Average2(L, TR), T) | -| 6 | Average2(L, TL) | -| 7 | Average2(L, T) | -| 8 | Average2(TL, T) | -| 9 | Average2(T, TR) | -| 10 | Average2(Average2(L, TL), Average2(T, TR)) | -| 11 | Select(L, T, TL) | -| 12 | ClampAddSubtractFull(L, T, TL) | -| 13 | ClampAddSubtractHalf(Average2(L, T), TL) | - - -`Average2` is defined as follows for each ARGB component: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -uint8 Average2(uint8 a, uint8 b) { - return (a + b) / 2; -} -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The Select predictor is defined as follows: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -uint32 Select(uint32 L, uint32 T, uint32 TL) { - // L = left pixel, T = top pixel, TL = top-left pixel. - - // ARGB component estimates for prediction. - int pAlpha = ALPHA(L) + ALPHA(T) - ALPHA(TL); - int pRed = RED(L) + RED(T) - RED(TL); - int pGreen = GREEN(L) + GREEN(T) - GREEN(TL); - int pBlue = BLUE(L) + BLUE(T) - BLUE(TL); - - // Manhattan distances to estimates for left and top pixels. - int pL = abs(pAlpha - ALPHA(L)) + abs(pRed - RED(L)) + - abs(pGreen - GREEN(L)) + abs(pBlue - BLUE(L)); - int pT = abs(pAlpha - ALPHA(T)) + abs(pRed - RED(T)) + - abs(pGreen - GREEN(T)) + abs(pBlue - BLUE(T)); - - // Return either left or top, the one closer to the prediction. - if (pL < pT) { - return L; - } else { - return T; - } -} -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The functions `ClampAddSubtractFull` and `ClampAddSubtractHalf` are performed -for each ARGB component as follows: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -// Clamp the input value between 0 and 255. -int Clamp(int a) { - return (a < 0) ? 0 : (a > 255) ? 255 : a; -} -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int ClampAddSubtractFull(int a, int b, int c) { - return Clamp(a + b - c); -} -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int ClampAddSubtractHalf(int a, int b) { - return Clamp(a + (a - b) / 2); -} -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -There are special handling rules for some border pixels. If there is a -prediction transform, regardless of the mode \[0..13\] for these pixels, the -predicted value for the left-topmost pixel of the image is 0xff000000, all -pixels on the top row are L-pixel, and all pixels on the leftmost column are -T-pixel. - -Addressing the TR-pixel for pixels on the rightmost column is -exceptional. The pixels on the rightmost column are predicted by using the modes -\[0..13\], just like pixels not on the border, but the leftmost pixel on the -same row as the current pixel is instead used as the TR-pixel. - -The final pixel value is obtained by adding each channel of the predicted value -to the encoded residual value. - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -void PredictorTransformOutput(uint32 residual, uint32 pred, - uint8* alpha, uint8* red, - uint8* green, uint8* blue) { - *alpha = ALPHA(residual) + ALPHA(pred); - *red = RED(residual) + RED(pred); - *green = GREEN(residual) + GREEN(pred); - *blue = BLUE(residual) + BLUE(pred); -} -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -### 4.2 Color Transform - -The goal of the color transform is to decorrelate the R, G, and B values of each -pixel. The color transform keeps the green (G) value as it is, transforms the -red (R) value based on the green value, and transforms the blue (B) value based -on the green value and then on the red value. - -As is the case for the predictor transform, first the image is divided into -blocks, and the same transform mode is used for all the pixels in a block. For -each block, there are three types of color transform elements. - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -typedef struct { - uint8 green_to_red; - uint8 green_to_blue; - uint8 red_to_blue; -} ColorTransformElement; -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The actual color transform is done by defining a color transform delta. The -color transform delta depends on the `ColorTransformElement`, which is the same -for all the pixels in a particular block. The delta is subtracted during the -color transform. The inverse color transform then is just adding those deltas. - -The color transform function is defined as follows: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -void ColorTransform(uint8 red, uint8 blue, uint8 green, - ColorTransformElement *trans, - uint8 *new_red, uint8 *new_blue) { - // Transformed values of red and blue components - int tmp_red = red; - int tmp_blue = blue; - - // Applying the transform is just subtracting the transform deltas - tmp_red -= ColorTransformDelta(trans->green_to_red, green); - tmp_blue -= ColorTransformDelta(trans->green_to_blue, green); - tmp_blue -= ColorTransformDelta(trans->red_to_blue, red); - - *new_red = tmp_red & 0xff; - *new_blue = tmp_blue & 0xff; -} -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -`ColorTransformDelta` is computed using a signed 8-bit integer representing a -3.5-fixed-point number and a signed 8-bit RGB color channel (c) \[-128..127\] -and is defined as follows: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int8 ColorTransformDelta(int8 t, int8 c) { - return (t * c) >> 5; -} -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -A conversion from the 8-bit unsigned representation (uint8) to the 8-bit signed -one (int8) is required before calling `ColorTransformDelta()`. The signed value -should be interpreted as an 8-bit two's complement number (that is: uint8 range -\[128..255\] is mapped to the \[-128..-1\] range of its converted int8 value). - -The multiplication is to be done using more precision (with at least 16-bit -precision). The sign extension property of the shift operation does not matter -here; only the lowest 8 bits are used from the result, and there the sign -extension shifting and unsigned shifting are consistent with each other. - -Now, we describe the contents of color transform data so that decoding can apply -the inverse color transform and recover the original red and blue values. The -first 3 bits of the color transform data contain the width and height of the -image block in number of bits, just like the predictor transform: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int size_bits = ReadBits(3) + 2; -int block_width = 1 << size_bits; -int block_height = 1 << size_bits; -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The remaining part of the color transform data contains `ColorTransformElement` -instances, corresponding to each block of the image. Each -`ColorTransformElement` `'cte'` is treated as a pixel in a subresolution image -whose alpha component is `255`, red component is `cte.red_to_blue`, green -component is `cte.green_to_blue`, and blue component is `cte.green_to_red`. - -During decoding, `ColorTransformElement` instances of the blocks are decoded and -the inverse color transform is applied on the ARGB values of the pixels. As -mentioned earlier, that inverse color transform is just adding -`ColorTransformElement` values to the red and blue channels. The alpha and green -channels are left as is. - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -void InverseTransform(uint8 red, uint8 green, uint8 blue, - ColorTransformElement *trans, - uint8 *new_red, uint8 *new_blue) { - // Transformed values of red and blue components - int tmp_red = red; - int tmp_blue = blue; - - // Applying the inverse transform is just adding the - // color transform deltas - tmp_red += ColorTransformDelta(trans->green_to_red, green); - tmp_blue += ColorTransformDelta(trans->green_to_blue, green); - tmp_blue += - ColorTransformDelta(trans->red_to_blue, tmp_red & 0xff); - - *new_red = tmp_red & 0xff; - *new_blue = tmp_blue & 0xff; -} -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -### 4.3 Subtract Green Transform - -The subtract green transform subtracts green values from red and blue values of -each pixel. When this transform is present, the decoder needs to add the green -value to both the red and blue values. There is no data associated with this -transform. The decoder applies the inverse transform as follows: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -void AddGreenToBlueAndRed(uint8 green, uint8 *red, uint8 *blue) { - *red = (*red + green) & 0xff; - *blue = (*blue + green) & 0xff; -} -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -This transform is redundant, as it can be modeled using the color transform, but -since there is no additional data here, the subtract green transform can be -coded using fewer bits than a full-blown color transform. - -### 4.4 Color Indexing Transform - -If there are not many unique pixel values, it may be more efficient to create a -color index array and replace the pixel values by the array's indices. The color -indexing transform achieves this. (In the context of WebP lossless, we -specifically do not call this a palette transform because a similar but more -dynamic concept exists in WebP lossless encoding: color cache.) - -The color indexing transform checks for the number of unique ARGB values in the -image. If that number is below a threshold (256), it creates an array of those -ARGB values, which is then used to replace the pixel values with the -corresponding index: the green channel of the pixels are replaced with the -index, all alpha values are set to 255, and all red and blue values to 0. - -The transform data contains the color table size and the entries in the color -table. The decoder reads the color indexing transform data as follows: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -// 8-bit value for the color table size -int color_table_size = ReadBits(8) + 1; -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The color table is stored using the image storage format itself. The color table -can be obtained by reading an image, without the RIFF header, image size, and -transforms, assuming the height of 1 pixel and the width of `color_table_size`. -The color table is always subtraction-coded to reduce image entropy. The deltas -of palette colors contain typically much less entropy than the colors -themselves, leading to significant savings for smaller images. In decoding, -every final color in the color table can be obtained by adding the previous -color component values by each ARGB component separately and storing the least -significant 8 bits of the result. - -The inverse transform for the image is simply replacing the pixel values (which -are indices to the color table) with the actual color table values. The indexing -is done based on the green component of the ARGB color. - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -// Inverse transform -argb = color_table[GREEN(argb)]; -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -If the index is equal to or larger than `color_table_size`, the argb color value -should be set to 0x00000000 (transparent black). - -When the color table is small (equal to or less than 16 colors), several pixels -are bundled into a single pixel. The pixel bundling packs several (2, 4, or 8) -pixels into a single pixel, reducing the image width respectively. Pixel -bundling allows for a more efficient joint distribution entropy coding of -neighboring pixels and gives some arithmetic coding-like benefits to the -entropy code, but it can only be used when there are 16 or fewer unique values. - -`color_table_size` specifies how many pixels are combined: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int width_bits; -if (color_table_size <= 2) { - width_bits = 3; -} else if (color_table_size <= 4) { - width_bits = 2; -} else if (color_table_size <= 16) { - width_bits = 1; -} else { - width_bits = 0; -} -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -`width_bits` has a value of 0, 1, 2, or 3. A value of 0 indicates no pixel -bundling is to be done for the image. A value of 1 indicates that two pixels are -combined, and each pixel has a range of \[0..15\]. A value of 2 indicates that -four pixels are combined, and each pixel has a range of \[0..3\]. A value of 3 -indicates that eight pixels are combined and each pixel has a range of \[0..1\], -that is, a binary value. - -The values are packed into the green component as follows: - - * `width_bits` = 1: For every x value, where x ≡ 0 (mod 2), a green - value at x is positioned into the 4 least significant bits of the - green value at x / 2, and a green value at x + 1 is positioned into the - 4 most significant bits of the green value at x / 2. - * `width_bits` = 2: For every x value, where x ≡ 0 (mod 4), a green - value at x is positioned into the 2 least-significant bits of the - green value at x / 4, and green values at x + 1 to x + 3 are positioned in - order to the more significant bits of the green value at x / 4. - * `width_bits` = 3: For every x value, where x ≡ 0 (mod 8), a green - value at x is positioned into the least significant bit of the green - value at x / 8, and green values at x + 1 to x + 7 are positioned in order - to the more significant bits of the green value at x / 8. - -After reading this transform, `image_width` is subsampled by `width_bits`. This -affects the size of subsequent transforms. The new size can be calculated using -`DIV_ROUND_UP`, as defined [earlier](#predictor-transform). - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -image_width = DIV_ROUND_UP(image_width, 1 << width_bits); -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -5 Image Data ------------- - -Image data is an array of pixel values in scan-line order. - -### 5.1 Roles of Image Data - -We use image data in five different roles: - - 1. ARGB image: Stores the actual pixels of the image. - 1. Entropy image: Stores the meta prefix codes (see - ["Decoding of Meta Prefix Codes"](#decoding-of-meta-prefix-codes)). - 1. Predictor image: Stores the metadata for the predictor transform (see - ["Predictor Transform"](#predictor-transform)). - 1. Color transform image: Created by `ColorTransformElement` values - (defined in ["Color Transform"](#color-transform)) for different blocks of - the image. - 1. Color indexing image: An array of size `color_table_size` (up to 256 ARGB - values) storing the metadata for the color indexing transform (see - ["Color Indexing Transform"](#color-indexing-transform)). - -### 5.2 Encoding of Image Data - -The encoding of image data is independent of its role. - -The image is first divided into a set of fixed-size blocks (typically 16x16 -blocks). Each of these blocks are modeled using their own entropy codes. Also, -several blocks may share the same entropy codes. - -**Rationale:** Storing an entropy code incurs a cost. This cost can be minimized -if statistically similar blocks share an entropy code, thereby storing that code -only once. For example, an encoder can find similar blocks by clustering them -using their statistical properties or by repeatedly joining a pair of randomly -selected clusters when it reduces the overall amount of bits needed to encode -the image. - -Each pixel is encoded using one of the three possible methods: - - 1. Prefix-coded literals: Each channel (green, red, blue, and alpha) is - entropy-coded independently. - 2. LZ77 backward reference: A sequence of pixels are copied from elsewhere in - the image. - 3. Color cache code: Using a short multiplicative hash code (color cache - index) of a recently seen color. - -The following subsections describe each of these in detail. - -#### 5.2.1 Prefix-Coded Literals - -The pixel is stored as prefix-coded values of green, red, blue, and alpha (in -that order). See [Section 6.2.3](#decoding-entropy-coded-image-data) for -details. - -#### 5.2.2 LZ77 Backward Reference - -Backward references are tuples of _length_ and _distance code_: - - * Length indicates how many pixels in scan-line order are to be copied. - * Distance code is a number indicating the position of a previously seen - pixel, from which the pixels are to be copied. The exact mapping is - described [below](#distance-mapping). - -The length and distance values are stored using **LZ77 prefix coding**. - -LZ77 prefix coding divides large integer values into two parts: the _prefix -code_ and the _extra bits_. The prefix code is stored using an entropy code, -while the extra bits are stored as they are (without an entropy code). - -**Rationale**: This approach reduces the storage requirement for the entropy -code. Also, large values are usually rare, so extra bits would be used for very -few values in the image. Thus, this approach results in better compression -overall. - -The following table denotes the prefix codes and extra bits used for storing -different ranges of values. - -Note: The maximum backward reference length is limited to 4096. Hence, only the -first 24 prefix codes (with the respective extra bits) are meaningful for length -values. For distance values, however, all the 40 prefix codes are valid. - -| Value range | Prefix code | Extra bits | -| --------------- | ----------- | ---------- | -| 1 | 0 | 0 | -| 2 | 1 | 0 | -| 3 | 2 | 0 | -| 4 | 3 | 0 | -| 5..6 | 4 | 1 | -| 7..8 | 5 | 1 | -| 9..12 | 6 | 2 | -| 13..16 | 7 | 2 | -| ... | ... | ... | -| 3072..4096 | 23 | 10 | -| ... | ... | ... | -| 524289..786432 | 38 | 18 | -| 786433..1048576 | 39 | 18 | - -The pseudocode to obtain a (length or distance) value from the prefix code is as -follows: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -if (prefix_code < 4) { - return prefix_code + 1; -} -int extra_bits = (prefix_code - 2) >> 1; -int offset = (2 + (prefix_code & 1)) << extra_bits; -return offset + ReadBits(extra_bits) + 1; -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -##### Distance Mapping - -As noted previously, a distance code is a number indicating the position of a -previously seen pixel, from which the pixels are to be copied. This subsection -defines the mapping between a distance code and the position of a previous -pixel. - -Distance codes larger than 120 denote the pixel distance in scan-line order, -offset by 120. - -The smallest distance codes \[1..120\] are special and are reserved for a close -neighborhood of the current pixel. This neighborhood consists of 120 pixels: - - * Pixels that are 1 to 7 rows above the current pixel and are up to 8 columns - to the left or up to 7 columns to the right of the current pixel. \[Total - such pixels = `7 * (8 + 1 + 7) = 112`\]. - * Pixels that are in the same row as the current pixel and are up to 8 - columns to the left of the current pixel. \[`8` such pixels\]. - -The mapping between distance code `distance_code` and the neighboring pixel -offset `(xi, yi)` is as follows: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -(0, 1), (1, 0), (1, 1), (-1, 1), (0, 2), (2, 0), (1, 2), -(-1, 2), (2, 1), (-2, 1), (2, 2), (-2, 2), (0, 3), (3, 0), -(1, 3), (-1, 3), (3, 1), (-3, 1), (2, 3), (-2, 3), (3, 2), -(-3, 2), (0, 4), (4, 0), (1, 4), (-1, 4), (4, 1), (-4, 1), -(3, 3), (-3, 3), (2, 4), (-2, 4), (4, 2), (-4, 2), (0, 5), -(3, 4), (-3, 4), (4, 3), (-4, 3), (5, 0), (1, 5), (-1, 5), -(5, 1), (-5, 1), (2, 5), (-2, 5), (5, 2), (-5, 2), (4, 4), -(-4, 4), (3, 5), (-3, 5), (5, 3), (-5, 3), (0, 6), (6, 0), -(1, 6), (-1, 6), (6, 1), (-6, 1), (2, 6), (-2, 6), (6, 2), -(-6, 2), (4, 5), (-4, 5), (5, 4), (-5, 4), (3, 6), (-3, 6), -(6, 3), (-6, 3), (0, 7), (7, 0), (1, 7), (-1, 7), (5, 5), -(-5, 5), (7, 1), (-7, 1), (4, 6), (-4, 6), (6, 4), (-6, 4), -(2, 7), (-2, 7), (7, 2), (-7, 2), (3, 7), (-3, 7), (7, 3), -(-7, 3), (5, 6), (-5, 6), (6, 5), (-6, 5), (8, 0), (4, 7), -(-4, 7), (7, 4), (-7, 4), (8, 1), (8, 2), (6, 6), (-6, 6), -(8, 3), (5, 7), (-5, 7), (7, 5), (-7, 5), (8, 4), (6, 7), -(-6, 7), (7, 6), (-7, 6), (8, 5), (7, 7), (-7, 7), (8, 6), -(8, 7) -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -For example, the distance code `1` indicates an offset of `(0, 1)` for the -neighboring pixel, that is, the pixel above the current pixel (0 pixel -difference in the X direction and 1 pixel difference in the Y direction). -Similarly, the distance code `3` indicates the top-left pixel. - -The decoder can convert a distance code `distance_code` to a scan-line order -distance `dist` as follows: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -(xi, yi) = distance_map[distance_code - 1] -dist = xi + yi * image_width -if (dist < 1) { - dist = 1 -} -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -where `distance_map` is the mapping noted above, and `image_width` is the width -of the image in pixels. - -#### 5.2.3 Color Cache Coding -{:#color-cache-code} - -Color cache stores a set of colors that have been recently used in the image. - -**Rationale:** This way, the recently used colors can sometimes be referred to -more efficiently than emitting them using the other two methods (described in -Sections [5.2.1](#prefix-coded-literals) and [5.2.2](#lz77-backward-reference)). - -Color cache codes are stored as follows. First, there is a 1-bit value that -indicates if the color cache is used. If this bit is 0, no color cache codes -exist, and they are not transmitted in the prefix code that decodes the green -symbols and the length prefix codes. However, if this bit is 1, the color cache -size is read next: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int color_cache_code_bits = ReadBits(4); -int color_cache_size = 1 << color_cache_code_bits; -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -`color_cache_code_bits` defines the size of the color cache (`1 << -color_cache_code_bits`). The range of allowed values for -`color_cache_code_bits` is \[1..11\]. Compliant decoders must indicate a -corrupted bitstream for other values. - -A color cache is an array of size `color_cache_size`. Each entry stores one ARGB -color. Colors are looked up by indexing them by `(0x1e35a7bd * color) >> (32 - -color_cache_code_bits)`. Only one lookup is done in a color cache; there is no -conflict resolution. - -In the beginning of decoding or encoding of an image, all entries in all color -cache values are set to zero. The color cache code is converted to this color at -decoding time. The state of the color cache is maintained by inserting every -pixel, be it produced by backward referencing or as literals, into the cache in -the order they appear in the stream. - -6 Entropy Code --------------- - -### 6.1 Overview - -Most of the data is coded using a [canonical prefix code][canonical_huff]. -Hence, the codes are transmitted by sending the _prefix code lengths_, as -opposed to the actual _prefix codes_. - -In particular, the format uses **spatially variant prefix coding**. In other -words, different blocks of the image can potentially use different entropy -codes. - -**Rationale**: Different areas of the image may have different characteristics. -So, allowing them to use different entropy codes provides more flexibility and -potentially better compression. - -### 6.2 Details - -The encoded image data consists of several parts: - - 1. Decoding and building the prefix codes. - 1. Meta prefix codes. - 1. Entropy-coded image data. - -For any given pixel (x, y), there is a set of five prefix codes associated with -it. These codes are (in bitstream order): - - * **Prefix code #1**: Used for green channel, backward-reference length, and - color cache. - * **Prefix code #2, #3, and #4**: Used for red, blue, and alpha channels, - respectively. - * **Prefix code #5**: Used for backward-reference distance. - -From here on, we refer to this set as a **prefix code group**. - -#### 6.2.1 Decoding and Building the Prefix Codes - -This section describes how to read the prefix code lengths from the bitstream. - -The prefix code lengths can be coded in two ways. The method used is specified -by a 1-bit value. - - * If this bit is 1, it is a _simple code length code_. - * If this bit is 0, it is a _normal code length code_. - -In both cases, there can be unused code lengths that are still part of the -stream. This may be inefficient, but it is allowed by the format. -The described tree must be a complete binary tree. A single leaf node is -considered a complete binary tree and can be encoded using either the simple -code length code or the normal code length code. When coding a single leaf -node using the _normal code length code_, all but one code length are zeros, -and the single leaf node value is marked with the length of 1 -- even when no -bits are consumed when that single leaf node tree is used. - -##### Simple Code Length Code - -This variant is used in the special case when only 1 or 2 prefix symbols are in -the range \[0..255\] with code length `1`. All other prefix code lengths are -implicitly zeros. - -The first bit indicates the number of symbols: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int num_symbols = ReadBits(1) + 1; -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The following are the symbol values. - -This first symbol is coded using 1 or 8 bits, depending on the value of -`is_first_8bits`. The range is \[0..1\] or \[0..255\], respectively. The second -symbol, if present, is always assumed to be in the range \[0..255\] and coded -using 8 bits. - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int is_first_8bits = ReadBits(1); -symbol0 = ReadBits(1 + 7 * is_first_8bits); -code_lengths[symbol0] = 1; -if (num_symbols == 2) { - symbol1 = ReadBits(8); - code_lengths[symbol1] = 1; -} -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The two symbols should be different. Duplicate symbols are allowed, but -inefficient. - -**Note:** Another special case is when _all_ prefix code lengths are _zeros_ (an -empty prefix code). For example, a prefix code for distance can be empty if -there are no backward references. Similarly, prefix codes for alpha, red, and -blue can be empty if all pixels within the same meta prefix code are produced -using the color cache. However, this case doesn't need special handling, as -empty prefix codes can be coded as those containing a single symbol `0`. - -##### Normal Code Length Code - -The code lengths of the prefix code fit in 8 bits and are read as follows. -First, `num_code_lengths` specifies the number of code lengths. - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int num_code_lengths = 4 + ReadBits(4); -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -The code lengths are themselves encoded using prefix codes; lower-level code -lengths, `code_length_code_lengths`, first have to be read. The rest of those -`code_length_code_lengths` (according to the order in `kCodeLengthCodeOrder`) -are zeros. - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int kCodeLengthCodes = 19; -int kCodeLengthCodeOrder[kCodeLengthCodes] = { - 17, 18, 0, 1, 2, 3, 4, 5, 16, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 -}; -int code_length_code_lengths[kCodeLengthCodes] = { 0 }; // All zeros -for (i = 0; i < num_code_lengths; ++i) { - code_length_code_lengths[kCodeLengthCodeOrder[i]] = ReadBits(3); -} -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Next, if `ReadBits(1) == 0`, the maximum number of different read symbols -(`max_symbol`) for each symbol type (A, R, G, B, and distance) is set to its -alphabet size: - - * G channel: 256 + 24 + `color_cache_size` - * Other literals (A, R, and B): 256 - * Distance code: 40 - -Otherwise, it is defined as: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int length_nbits = 2 + 2 * ReadBits(3); -int max_symbol = 2 + ReadBits(length_nbits); -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -If `max_symbol` is larger than the size of the alphabet for the symbol type, the -bitstream is invalid. - -A prefix table is then built from `code_length_code_lengths` and used to read up -to `max_symbol` code lengths. - - * Code \[0..15\] indicates literal code lengths. - * Value 0 means no symbols have been coded. - * Values \[1..15\] indicate the bit length of the respective code. - * Code 16 repeats the previous nonzero value \[3..6\] times, that is, - `3 + ReadBits(2)` times. If code 16 is used before a nonzero - value has been emitted, a value of 8 is repeated. - * Code 17 emits a streak of zeros of length \[3..10\], that is, `3 + - ReadBits(3)` times. - * Code 18 emits a streak of zeros of length \[11..138\], that is, - `11 + ReadBits(7)` times. - -Once code lengths are read, a prefix code for each symbol type (A, R, G, B, and -distance) is formed using their respective alphabet sizes. - -The Normal Code Length Code must code a full decision tree, that is, the sum of -`2 ^ (-length)` for all non-zero codes must be exactly one. There is however -one exception to this rule, the single leaf node tree, where the leaf node -value is marked with value 1 and other values are 0s. - -#### 6.2.2 Decoding of Meta Prefix Codes - -As noted earlier, the format allows the use of different prefix codes for -different blocks of the image. _Meta prefix codes_ are indexes identifying which -prefix codes to use in different parts of the image. - -Meta prefix codes may be used _only_ when the image is being used in the -[role](#roles-of-image-data) of an _ARGB image_. - -There are two possibilities for the meta prefix codes, indicated by a 1-bit -value: - - * If this bit is zero, there is only one meta prefix code used everywhere in - the image. No more data is stored. - * If this bit is one, the image uses multiple meta prefix codes. These meta - prefix codes are stored as an _entropy image_ (described below). - -The red and green components of a pixel define a 16-bit meta prefix code used in -a particular block of the ARGB image. - -##### Entropy Image - -The entropy image defines which prefix codes are used in different parts of the -image. - -The first 3 bits contain the `prefix_bits` value. The dimensions of the entropy -image are derived from `prefix_bits`: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int prefix_bits = ReadBits(3) + 2; -int prefix_image_width = - DIV_ROUND_UP(image_width, 1 << prefix_bits); -int prefix_image_height = - DIV_ROUND_UP(image_height, 1 << prefix_bits); -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -where `DIV_ROUND_UP` is as defined [earlier](#predictor-transform). - -The next bits contain an entropy image of width `prefix_image_width` and height -`prefix_image_height`. - -##### Interpretation of Meta Prefix Codes - -The number of prefix code groups in the ARGB image can be obtained by finding -the _largest meta prefix code_ from the entropy image: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int num_prefix_groups = max(entropy image) + 1; -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -where `max(entropy image)` indicates the largest prefix code stored in the -entropy image. - -As each prefix code group contains five prefix codes, the total number of prefix -codes is: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int num_prefix_codes = 5 * num_prefix_groups; -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Given a pixel (x, y) in the ARGB image, we can obtain the corresponding prefix -codes to be used as follows: - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -int position = - (y >> prefix_bits) * prefix_image_width + (x >> prefix_bits); -int meta_prefix_code = (entropy_image[position] >> 8) & 0xffff; -PrefixCodeGroup prefix_group = prefix_code_groups[meta_prefix_code]; -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -where we have assumed the existence of `PrefixCodeGroup` structure, which -represents a set of five prefix codes. Also, `prefix_code_groups` is an array of -`PrefixCodeGroup` (of size `num_prefix_groups`). - -The decoder then uses prefix code group `prefix_group` to decode the pixel -(x, y), as explained in ["Decoding Entropy-Coded Image -Data"](#decoding-entropy-coded-image-data). - -#### 6.2.3 Decoding Entropy-Coded Image Data - -For the current position (x, y) in the image, the decoder first identifies the -corresponding prefix code group (as explained in the last section). Given the -prefix code group, the pixel is read and decoded as follows. - -Next, read the symbol S from the bitstream using prefix code #1. Note that S is -any integer in the range `0` to -`(256 + 24 + ` [`color_cache_size`](#color-cache-code)` - 1)`. - -The interpretation of S depends on its value: - - 1. If S < 256 - 1. Use S as the green component. - 1. Read red from the bitstream using prefix code #2. - 1. Read blue from the bitstream using prefix code #3. - 1. Read alpha from the bitstream using prefix code #4. - 1. If S >= 256 & S < 256 + 24 - 1. Use S - 256 as a length prefix code. - 1. Read extra bits for the length from the bitstream. - 1. Determine backward-reference length L from length prefix code and the - extra bits read. - 1. Read the distance prefix code from the bitstream using prefix code #5. - 1. Read extra bits for the distance from the bitstream. - 1. Determine backward-reference distance D from the distance prefix code - and the extra bits read. - 1. Copy L pixels (in scan-line order) from the sequence of pixels starting - at the current position minus D pixels. - 1. If S >= 256 + 24 - 1. Use S - (256 + 24) as the index into the color cache. - 1. Get ARGB color from the color cache at that index. - -7 Overall Structure of the Format ---------------------------------- - -Below is a view into the format in Augmented Backus-Naur Form (ABNF) -[RFC 5234][] [RFC 7405][]. It does not cover all details. The end-of-image (EOI) -is only implicitly coded into the number of pixels (image_width * image_height). - -Note that `*element` means `element` can be repeated 0 or more times. `5element` -means `element` is repeated exactly 5 times. `%b` represents a binary value. -

If ACTION-IF-FOUND is not specified, the default action -# will define HAVE_PTHREAD. -# -# Please let the authors know if this macro fails on any platform, or if -# you have any other suggestions or comments. This macro was based on work -# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help -# from M.

If options \fB\-q\fP or \fB\-m\fP are subsequently used, they will -invalidate the effect of this option. -.TP -.BI \-alpha_q " int -Specify the compression factor for alpha compression between 0 and 100. -Lossless compression of alpha is achieved using a value of 100, while the lower -values result in a lossy compression. The default is 100. -.TP -.BI \-preset " string -Specify a set of pre\-defined parameters to suit a particular type of -source material. Possible values are: \fBdefault\fP, \fBphoto\fP, -\fBpicture\fP, \fBdrawing\fP, \fBicon\fP, \fBtext\fP.

Skip, segment, and mode -information can use up almost all these 4 bits (although the case is unlikely), -which is problematic for very large images. The partition_limit factor controls -how frequently the most bit\-costly mode (intra 4x4) will be used. This is -useful in case the 512k limit is reached and the following message is displayed: -\fIError code: 6 (PARTITION0_OVERFLOW: Partition #0 is too big to fit 512k)\fP. -If using \fB\-partition_limit\fP is not enough to meet the 512k constraint, one -should use less segments in order to save more header bits per macroblock. -See the \fB\-segments\fP option. - -.SS LOGGING OPTIONS -These options control the level of output: -.TP -.B \-v -Print extra information (encoding time in particular). -.TP -.B \-print_psnr -Compute and report average PSNR (Peak\-Signal\-To\-Noise ratio). -.TP -.B \-print_ssim -Compute and report average SSIM (structural similarity -metric, see https://en.wikipedia.org/wiki/SSIM for additional details). -.TP -.B \-print_lsim -Compute and report local similarity metric (sum of lowest error amongst the -collocated pixel neighbors). -.TP -.B \-progress -Report encoding progress in percent. -.TP -.B \-quiet -Do not print anything. -.TP -.B \-short -Only print brief information (output file size and PSNR) for testing purposes. -.TP -.BI \-map " int -Output additional ASCII\-map of encoding information.

One of 'none', -\&'fast' or 'best', in increasing complexity and slowness order. Default is -\&'fast'. Internally, alpha filtering is performed using four possible -predictions (none, horizontal, vertical, gradient). The 'best' mode will try -each mode in turn and pick the one which gives the smaller size. The 'fast' -mode will just try to form an a priori guess without testing all modes. -.TP -.BI \-alpha_method " int -Specify the algorithm used for alpha compression: 0 or 1. Algorithm 0 denotes -no compression, 1 uses WebP lossless format for compression. The default is 1. -.TP -.B \-exact -Preserve RGB values in transparent area.

Also, since swig_type_info structures store pointers to - * swig_cast_info structures and swig_cast_info structures store pointers back - * to swig_type_info structures, we need some lookup code at initialization. - * The idea is that swig generates all the structures that are needed. - * The runtime then collects these partially filled structures. - * The SWIG_InitializeModule function takes these initial arrays out of - * swig_module, and does all the lookup, filling in the swig_module.types - * array with the correct data and linking the correct swig_cast_info - * structures together. - * - * The generated swig_type_info structures are assigned statically to an initial - * array. We just loop through that array, and handle each type individually. - * First we lookup if this type has been already loaded, and if so, use the - * loaded structure instead of the generated one. Then we have to fill in the - * cast linked list. The cast data is initially stored in something like a - * two-dimensional array. Each row corresponds to a type (there are the same - * number of rows as there are in the swig_type_initial array). Each entry in - * a column is one of the swig_cast_info structures for that type. - * The cast_initial array is actually an array of arrays, because each row has - * a variable number of columns. So to actually build the cast linked list, - * we find the array of casts associated with the type, and loop through it - * adding the casts to the list. The one last trick we need to do is making - * sure the type pointer in the swig_cast_info struct is correct. - * - * First off, we lookup the cast->type name to see if it is already loaded. - * There are three cases to handle: - * 1) If the cast->type has already been loaded AND the type we are adding - * casting info to has not been loaded (it is in this module), THEN we - * replace the cast->type pointer with the type pointer that has already - * been loaded. - * 2) If BOTH types (the one we are adding casting info to, and the - * cast->type) are loaded, THEN the cast info has already been loaded by - * the previous module so we just ignore it. - * 3) Finally, if cast->type has not already been loaded, then we add that - * swig_cast_info to the linked list (because the cast->type) pointer will - * be correct. - * ----------------------------------------------------------------------------- */ - -#ifdef __cplusplus -extern "C" { -#if 0 -} /* c-mode */ -#endif -#endif - -#if 0 -#define SWIGRUNTIME_DEBUG -#endif - - -SWIGRUNTIME void -SWIG_InitializeModule(void *clientdata) { - size_t i; - swig_module_info *module_head, *iter; - int init; - - /* check to see if the circular list has been setup, if not, set it up */ - if (swig_module.next==0) { - /* Initialize the swig_module */ - swig_module.type_initial = swig_type_initial; - swig_module.cast_initial = swig_cast_initial; - swig_module.next = &swig_module; - init = 1; - } else { - init = 0; - } - - /* Try and load any already created modules */ - module_head = SWIG_GetModule(clientdata); - if (!module_head) { - /* This is the first module loaded for this interpreter */ - /* so set the swig module into the interpreter */ - SWIG_SetModule(clientdata, &swig_module); - } else { - /* the interpreter has loaded a SWIG module, but has it loaded this one?
