OK.One of my friends want to find a way to find the RGB or RGBA values of each pixel of the image.So are there any OpenGL functions to do this?
Any article or suggestion?

Also glReadBuffer will help too. You'll get an array of RGB values for each pixel in the screen.
glReadPixels would help but that doesn't save a complete screen.

For more complex imaging stuff there are nvidia imaging extensions to opengl.
