[PyQt] Re: rendering svg

[Niels Egberts]

Now I have found this:

self.picture = QtGui.QPicture()
self.picture.load("/home/user/grid.jpg")

And it gives the error:

QPicturePaintEngine::checkFormat: Incorrect header

I have tried with a jpg, bmp, svg and an png but all of them return an
"incorrect header". What am I doing wrong?
