[PyQt] Odd QImage behavior

[Matt Smith]

I made a mistake about what works and what doesn't.  If I use

nimage = QtGui.QImage(total.data,w,h,QtGui.QImage.Format_Indexed8)
nimage.setColorTable(COLORTABLE)

Then there is strange wrapping that occurs if the image is not the correct size
If I use:

nimage = QtGui.QImage(total.data,w,h,QtGui.QImage.Format_RGB32)
nimage.ndarray = total

Then it works fine, of course for both of those examples 'total' has a different shape.

I think that is the problem for two reasons.  First it depends on the
size of the array, and Second the .ndarray part is left off of first
example, and doesn't change anything when I include it.

I have checked the data by comparing sizes.  Also I implement a line
detection algorithm and the lines are drawn according to the correct
shape, while the data is displayed warped.
