View Full Version : read the whole viewport pixels

Thanks, zeckensack. I solved the problem as you said.

There is a problem that if the viewport is larger than the windows size(I have to fix the viewport for my application), the glReadPixels return the frame-buffer in windows size, which means Values for pixels that lie outside the window connected to the current OpenGL context are undefined.

is there a way I can read the whole viewport pixels ignoring the size of windows(MFC windows)?

please help me out.

You can use a pbuffer.
