HBITMAP to Bitmap in WinUI 3

[gautambjain]

There using to be System.Drawing.Image.FromHbitmap in .Net Framework, but I don't know how to do the same in WinUI.

I have handle to HBITMAP. Have looked at several places. But don't know how to create objects of type Bitmap, BitmapSource, ImageSource from HBITMAP.

Basically I want to draw it on a control such as StackPanel etc.

Kindly please help.

I generally use a WriteableBitmap (you can see for example the GetCaptureWriteableBitmap function that I used in CMediaEngine.cs to convert a HBITMAP (m_hBitmapCapture) that I set as Image.Source in SaveFrameDialog function in MainWindow.xaml.cs)

Thanks a lot @castorix . You have helped me several times . God bless. Today. on another forum also, I found your answer very useful.

So you're creating a new in-memory bitmap, rendering to it, and then copying it to the WriteableBitmap? Wouldn't it be much more memory efficient to render directly to the WriteableBitmap? Except it offers no way in C# to get the buffer, for... reasons.
