[PyQt] Re: QPixmap / QImage from numpy or string

[Matthew Smith]

When I do this I use an RGB image becuase each line of your image needs
to be a multiple of 32bits or something like that, it says it in the
QImage documention.

Also I need to keep a reference to my original array.


total = numpy.zeros((h,w,4),numpy.uint8)

#code to fill total with image data

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

I got this base on some code from the PyQwt mailing list. Ill attach it.
