Is there anyone that has done GL.ReadPixels() with OpenTK?
Preferrably I'd like to avoid unsafe sections.
Here's what I've got so far:
float rgb = new float; GL.ReadPixels(0,0,1,1, PixelFormat.Rgb, PixelType.Float, ???);
.. where ??? means I don't know what to type ;)
(this is for alpha-blended texture testing .. I want to read out the pixel Red,Green,Blue values written by OpenGL to the colorbuffer!)
