Just to throw my $0.02 in, are "width" and "height" always larger than the originals? And do we know what QPixmap::copy does in that case? I ask because http://www.greyc.ensicaen.fr/ensicaen/Docs/Qt4/qpixmap.html says that copy "Returns a deep copy of the subset of the pixmap that is specified by the given rectangle. " So what does it do when the rectangle is too big? I don't know and it doesn't say, but if what it does is copy nothing or make a blank pixmap, that might explain what you are seeing. Or I could be totally wrong, since I'm just learning Qt.
