Saving OpenGL Graphics as a JPEG

[kal_mans]

Hello,
If i have a Layout drawn using OpenGl Commands...the layout may be a Rectangle or anything...
now if i want to save that a JPEG....how can i do that...?
i tried out the GrabWidget option available wid the Designer but doesnt seems to work..
so is there any options available in OpenGL to do this....?
Waiting for ur replies..

ksnapshot will take a screenshot of your OGL app. It works perfectly.

You mean from your program? render, glFinish(); setup_pixel_transfer(); glReadPixels(...); and then use something in the Qt (I'm guessing "Layout" and "Designer" refer to Qt) API that takes a raw RGB image and saves it to a JPEG.
