for PyQt4, that seems to have changed to QImage(buffer, width, height,
format), where format is a QImage.Format_XXX specifier.
in other words, this should work:
if im.mode != "RGB":
im = im.convert("RGB")
data = im.tostring("raw", "BGRX")
image = QImage(data, im.size[0], im.size[1],
QImage.Format_RGB32)
note that the QImage descriptor will point into the data buffer, so you
must hang on to data for as long you're using image.
(I haven't found a way to attach a user attribute to a QImage class; it
doesn't complain when I do that, but it doesn't seem to do the right
thing...)
