Qt and Jpeg plugin problem

Question

Hi!

When I try to save pixmap in jpg format then I get an error in console QJpegHandler: unable to write image of format 7 and the result image is corrupt.

How to fix this problem?

Qt 4.6.2 on windows mobile. On symbian it works fine without any problems.

Thanks in advance.

I suspect that the JPEG image plugin is not linked with your executable. To see which image formats are available, try:

QImageWriter::supportedImageFormats()

See the Qt documentation for more information. In case JPEG is not supported, build the JPEG plugin that comes with Qt and link it with your application.
