Feature/pdf blackwhite - #2589

Node.js 20 is deprecated. The following actions target Node.js 20 but are being forced to run on Node.js 24: actions/checkout@v4, actions/setup-dotnet@v4, github/codeql-action/analyze@v3, github/codeql-action/init@v3. For more information see: https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/

Non-nullable field '_shaper' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the field as nullable.

The field 'PieSliceCollection.totalValue' is assigned but its value is never used

The field 'CircularArc.Width' is never used

The field 'CircularArc.ChordB' is never used

The field 'CircularArc.ChordA' is never used

The field 'CircularArc.D' is never used

The field 'CircularArc.Height' is never used

The field 'FontsBinaryReader._numberOfReadBytes' is assigned but its value is never used

The result of the expression is always 'false' since a value of type 'int' is never equal to 'null' of type 'int?'

The annotation for nullable reference types should only be used in code within a '#nullable' annotations context.

Cannot build an overlay database because build-mode is set to "undefined" instead of "none". Falling back to creating a normal full database instead.
