+# ImageCropper
+
+`BootstrapBlazor.ImageCropper` bundles [Cropper.js 2.2.0](https://github.com/fengyuanchen/cropperjs/releases/tag/v2.2.0).
+No CDN scripts or Cropper.js stylesheet are required. The component loads its local JavaScript and styles automatically.
+
+## Example
+
+```razor
+<ImageCropper @ref="_cropper" Url="@_url" Options="@_options"
+             OnCropAsync="@OnCropAsync" OnCropChangedAsync="@OnCropChangedAsync" />
+<div class="bb-cropper-preview bb-cropper-preview-lg"></div>
+<p>Selection: @_data.Width.ToString("F0") x @_data.Height.ToString("F0")</p>
+<Button Text="Crop" OnClick="@(() => _cropper!.Crop())" />
+<Button Text="Zoom in" OnClick="@(() => _cropper!.Zoom(0.1))" />
+<Button Text="Zoom out" OnClick="@(() => _cropper!.Zoom(-0.1))" />
+<Button Text="Rotate" OnClick="@(() => _cropper!.Rotate(90))" />
+<Button Text="Flip horizontally" OnClick="@(() => _cropper!.FlipHorizontal())" />
+<Button Text="Flip vertically" OnClick="@(() => _cropper!.FlipVertical())" />
+<Button Text="Square" OnClick="@(() => _cropper!.SetAspectRatio(1))" />
+<Button Text="16:9" OnClick="@(() => _cropper!.SetAspectRatio(16.0 / 9))" />
+<Button Text="Free ratio" OnClick="@(() => _cropper!.SetAspectRatio(null))" />
+<Button Text="Reset" OnClick="@(() => _cropper!.Reset())" />
+<Button Text="Export JPEG" OnClick="@ExportAsync" />
+@if (_result != null)
+{
+    <img src="@_result" alt="Cropped image" />
+}
+
+@code {
+    private ImageCropper? _cropper;
+    private string _url = "images/photo.jpg";
+    private string? _result;
+    private ImageCropperData _data;
+    private readonly ImageCropperOption _options = new()
+    {
+        CanvasHeight = 360,
+        InitialFit = "contain",
+        AutoCropArea = 0.8f,
+        Keyboard = true,
+        Preview = ".bb-cropper-preview"
+    };
+
+    private Task OnCropAsync(ImageCropperResult result)
+    {
+        _result = result.Data;
+        // result.Stream provides the decoded image.
+        return Task.CompletedTask;
+    }
+
+    private Task OnCropChangedAsync(ImageCropperData data)
+    {
+        _data = data;
+        return Task.CompletedTask;
+    }
+
+    private async Task ExportAsync()
+    {
+        await _cropper!.Crop(new ImageCropperExportOptions
+        {
+            Width = 800,
+            MimeType = "image/jpeg",
+            Quality = 0.9,
+            FillColor = "#fff"
+        });
+    }
+}
+```
+
+## Operations and export
+
+Existing `Crop()`, `Replace(url)`, `Reset()`, `Rotate(degrees)`, `Clear()`,
+`SetDragMode("crop" | "move" | "none")`, `Enable()` and `Disable()` methods remain available.
+`IsDisabled` is respected on the first render and subsequent updates. Changing `Url` replaces the image;
+setting it to null or empty removes the image. An empty component can be initialized and later populated
+with `Replace(url)`. `Replace` waits for the image to load and resets the image transform and selection.
+Image-loading and export failures propagate through JS interop instead of returning an empty result.
+While disabled, image-transform methods, `Replace`, `Reset`, `Clear` and `SetAspectRatio` do nothing;
+export remains available. Parameter-driven `Url` changes are still applied.
+
+`Zoom(ratio)` changes the image scale, `Move(x, y)` moves the image in canvas pixels,
+and `FlipHorizontal()` / `FlipVertical()` toggle mirroring. `SetAspectRatio(null)` restores a free ratio.
+For circular crops, set `ImageCropperOption.IsRound = true`; the selection always remains square.
+For live circular previews, also apply `.bb-cropper-preview-round` to each preview container;
+this makes the preview square before the 50% border radius is applied:
+
+```razor
+<ImageCropper Url="@_url" Options="@_roundOptions" />
+<div class="bb-cropper-preview bb-cropper-preview-round bb-cropper-preview-lg"></div>
+
+@code {
+    private readonly ImageCropperOption _roundOptions = new()
+    {
+        IsRound = true,
+        Preview = ".bb-cropper-preview-round"
+    };
+}
+```
+
+`Crop(ImageCropperExportOptions)` supports PNG, JPEG and WebP. Without a size, the export uses source-image
+pixels, not the displayed canvas resolution. Setting width or height scales the result while preserving
+the selection aspect ratio. When both are set, the result fits inside that rectangle without stretching.
+Quality ranges from 0 to 1 and affects JPEG/WebP. PNG/WebP default to a transparent background;
+JPEG defaults to white. Circular PNG/WebP exports preserve transparent corners unless a fill color is set.
+Browsers that cannot export the requested format report an error rather than silently returning PNG.
+
+`OnCropChangedAsync` fires at the end of a pointer gesture and after supported keyboard operations.
+Its rectangle uses source-image pixels relative to the bounding box of the transformed image.
+`Rotate` is in degrees; `ScaleX` and `ScaleY` indicate mirroring (`1` or `-1`).
+Do not use the rectangle as an unrotated source-image crop after rotating the image.
+
+## Migration from Cropper.js 1.6.2
+
+Cropper.js 2 uses custom elements. Existing method names and compatible options are adapted by the component,
+but the interaction and rendering implementation are different.
+
+| Option | Behavior |
+| --- | --- |
+| `ViewMode` | Deprecated and ignored. `InitialFit` controls initial sizing only; it does not enforce image/selection boundaries. |
+| `Responsive`, `Restore` | Deprecated and ignored. The canvas responds to container resizing automatically. |
+| `CheckCrossOrigin` | Deprecated and ignored. Use `CrossOrigin = "anonymous"` or `"use-credentials"` and configure server CORS. |
+| `CheckOrientation` | Deprecated and ignored. Image orientation is handled by the browser; preprocess images if needed. |
+| `DragMode`, `ToggleDragModeOnDblclick` | Mapped to the canvas handle action; double-click toggles crop/move. |
+| `InitialAspectRatio`, `AspectRatio`, `AutoCrop`, `AutoCropArea` | Mapped to the selection. `InitialAspectRatio` accepts a positive invariant-culture numeric string. `AutoCropArea` remains an area fraction from 0 to 1. |
+| `Modal`, `Guides`, `Center`, `Highlight`, `Background` | Mapped to shade/grid/crosshair/handle/canvas properties. |
+| `Movable`, `Rotatable`, `Scalable`, `Zoomable`, `ZoomOnTouch`, `ZoomOnWheel`, `WheelZoomRatio` | Adapted to image properties and canvas gesture handling. Flipping respects `Scalable`; zooming respects `Zoomable`. |
+| `CropBoxMovable`, `CropBoxResizable` | Mapped to selection properties. |
+| `MinCanvasWidth`, `MinCanvasHeight`, `MinContainerWidth`, `MinContainerHeight` | Minimum canvas CSS dimensions; canvas-specific values take precedence. |
+| `MinCropBoxWidth`, `MinCropBoxHeight` | Reject selection changes below the minimum dimensions. |
+| `Preview` | A CSS selector for preview containers. Each receives a live `cropper-viewer`, removed on disposal. |
+| `IsRound`, `Radius` | Applied to the selection; `IsRound` also masks the exported image. |
+
+New options include `CanvasHeight` (default 360), `InitialFit` (`contain` or `cover`),
+`Keyboard` (default false), `DynamicSelection` (default false), and `CrossOrigin`.
+Options are applied at initialization. Use `SetAspectRatio` for runtime ratio changes.
+Keyboard shortcuts include arrow keys to move the selection and Delete to clear it.
+The Cropper.js 2 keyboard handler is document-level, so enable it for only one cropper at a time.
+
+Custom styles targeting Cropper.js 1 classes such as `.cropper-view-box` must be migrated to the
+`cropper-*` custom elements. Keep using the `.bb-cropper-preview-*` helper classes for preview sizes.
