Description

I need to pick a color from a bitmap, but the GetPixel function only exists in the default Bitmap class. Also graphics from image would allow drawing on top of an existing bitmap and not creating a blank one, which Device.CreateBitmapGraphics is doing.

Edit: You can make an empty graphic and draw the bitmap on it, but I meant that you can't directly edit the existing bitmap, just paste it onto the graphic, and there's no way to get the result back.

Contributor guide

Research direction
Examine how GetPixel, SetPixel, and Graphics.FromImage work in the System.Drawing.Bitmap class and implement equivalent Direct2D methods using the existing device context and bitmap objects.
