QImage (..) & QImage::save() always return NULL value - why?

[whitesail]

Did you try "JPEG" instead of "JPG"?

Tried to - no difference...

Was your Qt built with JPEG support?

Yes, sure - Loaded images are saved without any troubles.

What does QImageIO :: outputFormats() return?

Never tried it... I will tomorrow - Don't have a QT installed here to try your advises. If you have a working example consisting of creation and saving an QImage object , pls, post it here.

Thanks a lot for your help!
