AngelDaniel,
As you can see in the code, the solution that I came up with does use a TPixmap, glReadPixels and SavePixmapPNG. Its only problem was that the image was inverted which Suco-X solved by suggesting use of YFlipPixmap.
The result is a short and fast solution to the problem and I'm happy with that.
If you have a substantially different and perhaps better method then I'd be very appreciative if you post a working bit of code.
Failing that I don't see a lot of value from your posts. You seem to mis-read the question, point out things already in evidence and question why I want to do or not do things that were never raised by me.
Help and insight are appreciated but waffle is not.
