**noufalk** · 24th July 2007, 12:45

Hi everybody..

When I am trying to write TIFF Image as Jpeg file in our application on MacOSX ,it's getting failed.I am using Qt3.3.8 commercial edition.But I dont have any problem in windows.Am getting message as follows .

"QImageIO::write: No such image format handler: JPEG"

Any suggestion will be highly appreciable

That's probably because your Qt distribution hasn't been compiled with Jpeg Support enabled...

You can try to recompile your own Qt libs, enabling jpeg support (take a look at 'configure --help' command )

I had already configured Qt for jpeg.

Just to assure, did you check configure output that the JPEG support was properly enabled? What does QImageIO::outputFormats() output?
