I had a similar 'vertical skewing' effect, some days ago. In a slightly different context but maybe for the same reasons.
QImage img = getImageFromSomewhere(); const int srcBpl = img.bytesPerLine(); const uchar *imageData = alphaMask.bits(); The (non-const) bits() call may detach the image, which causes a realignment of the image data. So if the image was unpadded, before, the srcBpl is now invalid! Result is those skews. The easiest solution in my case was to change the first line to: const QImage img = getImageFromSomewhere(); which makes sure that the non-detaching version of bits() is called. (Credits again to dteske for coming up with that solution) ..just an idea of where to look :) Alessandro Jason H wrote: > Qt 4.5 RC1.Windows Open Source Binary install. > > ATI Radeon Moble chipset. _______________________________________________ Qt4-preview-feedback mailing list [email protected] http://lists.trolltech.com/mailman/listinfo/qt4-preview-feedback
