Get a Bitmap from a WPF application window?

The Winforms System.Windows.Forms.Control class has an instance method "DrawToBitmap" which I think is very useful in a variety of circumstances. I'm wondering if there's an equivalent way of getting a System.Drawing.Bitmap from a WPF application?

I realize I could do some P/Invoke stuff to just get the application window, however I don't like this because it doesn't accomodate the 64bit transition very well, and doesn't let me render sub-controls only, as DrawToBitmap does.

Thanks, Richard

Solution

  • Use RenderTargetBitmap as on MSDN

    RenderTargetBitmap bitmap = new RenderTargetBitmap(width, height, 96, 96, PixelFormats.Pbgra32);
bitmap.Render(this.YourVisualControlNameGoesHere);
