Burning in graphics

After displaying an image using glTexImage2d and mapping the quadrilaterals to a texture map and then drawing some graphics on top of that, I need to “burn in” the graphics so I can save the pixels (with the graphics) to a single disk file. Is the only way to use glReadPixels()? Any tips would be appreciated. Thanks.


Well, you could always hit Print Screen and paste from the clipboard. :slight_smile:
Yes, I think glReadPixels is the only way to do it.
