PySide Image Formats
I'm trying to use windows with PySide. However my code that ran fine in Linux doesn't want to work in windows. I'm creating a QImage and then using loadFromData() to load the data from a string. The image format is JPEG which is normally supported via a plugin. However that plugin doesn't seem to have been installed with PySide. I tried using addLibraryPath to point to the plugins but that didn't work either. I still get a isNull() == true image back.
*edit * It seems that the issue is that PySide isn't loading any plugins.
Here's what I currently have:
@from PySide.QtGui import QImage
from PySide.QtGui import *
from PySide.QtCore import *
app = QApplication(sys.argv)
for v in QCoreApplication.libraryPaths():
for v in QImageReader.supportedImageFormats():
img = QImage();
Still, no matter what I do, It always fails. The list out of formats includes .pngs which load fine. But the .jpg plugins are not loading. And therefore fail.
This is a bug on PySide windows package, they do not contain the necessary Qt plug ins. I recommend to you, remove the Qt dll installed with Pyside package, and install the official Qt package.
That did the trick! I copied the contents of the Qt/bin directory into the Python26/Lib/site-packages/PySide overwriting all the QT files there. And it works like a charm.
tbcpp, Roman Lacko (the guy who volunteered to do the Windows packaging) told he's aware of the issue and the next installer contains the plugins (including a currently missing sqllite plugin).
