[Csgl-users] Fw: OpenGLControl.DrawToBitmap

[<Hai...@co...>]

Hello,

I have a OpenGLControl.  I need get a bitmap from it. But I only get a
black bitmap.   Below is the code snippet.   What is the right way to do
this?

  Bitmap bitmap = new Bitmap(theWidth, theHeight, thePixelFormat);
  myOpenGLControl.DrawToBitmap(bitmap, new Rectangle(0, 0, Width, Height));
Thanks for any help.
