Closed neoxeo closed 4 months ago

@generalloki

Could you add Bitmap.Clone(Rectangle, PixelFormat) (https://learn.microsoft.com/en-us/dotnet/api/system.drawing.bitmap.clone?view=windowsdesktop-8.0#system-drawing-bitmap-clone(system-drawing-rectangle-system-drawing-imaging-pixelformat)

Thanks

This method with PixelFormat parameter looks complex to implement as we need to map it to wxWidgets call. For what reason are you going to use it? What is the task?

Here is the application I try to convert to AlternetUI : https://github.com/tgraupmann/WinForm_Ollama_Copilot

Here is the code used for OCR and it use "CopyFromScreen" and "Bitmap.Clone" : https://github.com/tgraupmann/WinForm_Ollama_Copilot/blob/master/OcrManager.cs

And here you can see how it works : https://www.youtube.com/watch?v=WHM-Bc9k04E

I would ask in other words: What PixelFormat values you would use? I don't see using of Bitmap.Clone there
