Windows 7 and QPixmap

**GimpMaster** · 12th November 2009, 18:58

I'm having difficulty loading a jpeg image into a QPixmap in windows 7. I've even attempted running the Qt demo: imagescaling.exe and browsing and loading in there as well.

Now granted I am running Qt 4.5.1 and not the latest 4.5.3, however looking through the release notes of those versions i didn't see any mention of a bug fix. I've looked through the bug reports and I could not see anything either.

Has anybody else seen this problem? It loads bmps just fine but not JPEGs.

Also I wasn't sure of the best way to search the forums for windows 7 or the bug tracker on trolltech. I tried Windows 7, "Windows 7", windows7, etc. Not sure what the best combination is.

Thanks!

As far as I remember Qt 4.6 will be the first that supports Windows 7.
Try the release candidate which should come out next week

But what problem do you have exactly? Is it displaying any dialog window with errors or what? Can describe what those difficulties are?

Are you sure that your qt app finds the necessary jpeg-plugin-dll?
it must be in imageformats directory

I know this is an old thread but I just wanted to say that olidem was correct and I was missing the jpeg-plugin. I did not know you had to distribute those (actually I did not know they existed). Anyways works great.
