glReadPixels save as jpeg

Hi,

I want to save a screenshot of my GLCanvas. I use glReadPixels and my output is a png-file.
My problem is that the resulting image is only black - can anybody tell me the reason for this?

Thanks.

Have you tried the fast screenshot function in this thread?

There are links to some other screenshot utlities in this bug report, but you’ll have to search the forum for the subjects.

I found an example, that works.

Thanks
