I'm seeing a strange issue with either QPixmap or QImage loading
from a data string. In pyqt 4.4.4, the following attached example
code produces an image - it looks like noise as expected. But with
pyqt 4.5.1, it appears completely blank. I expect to see the noise-
like image. Am I doing something wrong, or has something changed
with regards to this in 4.5?
I'm running on Mac OS X 10.5.7 and python 2.5.4 using pyqt installed
from Macports. Note: I modified my local portfile to install pyqt
4.5.1 because Macports is currently at version 4.4.4.
The problem turned out to be in my makeColorTable method. Specifically
the qRgb() function returns a different value for me with pyqt 4.5.1
and sip 4.8.1 than the value returned using 4.4.4/4.7.9. Should there
be any difference between versions for that function?
For example, for qRgb(0,0,0) I get -16777216 with 4.4.4 and 4278190080
with 4.5.1.
Cheers!
Frank
