Feature Request - PDF Ink Signature

[Tanmaya-Code-Library]

Hi Team,

I think CEFShARP does not support the chromium feature "PDF Ink Signatures". This feature setting is available in chromium setting at chrome://flags/#pdf-ink2.

If the Chromium feature "PDF Ink Signatures" is not supported CEFSHARP, kindly include this feature. If this feature is available in CEFSHAP, please provide the code snippet for the same.

I tried by using the following code. It did not work.

cefSettings.CefCommandLineArgs.Add("enable-features", "PDFAnnotations,Ink");

You need to have the ENABLE_INK define during building cef which it does not by default. CefSharp uses the official spotify builds so until it become default to on there you will need to have custom compiles. This would be considered beyond scope for now.

the flag does exist right now (and you can set flags in cefsharp) but:

• wpf - hand always appears on pdf does not work likely as is offscreen so inking may just not be supported
• wpf.hwndhost - show correct cursor (colored dot etc) but drawing does not show anything on pdf, likely would work with correct build flag.
• winforms - doesn't work with highdpi for me so couldn't test.
