Package: libqt4-core
Version: 4.0.0-2
I'm trying to use the Qt4 Debian packages with a little test program.
In a QLabel I put a jpeg images how pixmap but when execute test it's
impossible show any jpeg image.
if I load a png image i can see it.
I run my little test in konsole and
when I show a jpeg image i get:
Painter must be active to set rendering hints
QPainter::end: Painter is not active, aborted
QPixmap::convertFromImage: Cannot convert a null image
QPainter::begin(), paintdevice returned engine == 0, type: 3
because QImage is null (3° row).
If I get a copy of Qt4 source from Trolltech and I compile it by myself with:
./configure -system-libjpeg -.....
or
without -system-libjpeg
I can found in plugin directory
imageformats/libqjpeg.so
but in your Qt4 package this file can not be
found in any location.
I compile my test with my Qt4 build and so I can show jpeg image.
My system:
OS: Debian Sid
Kernel: 2.6.12 base + Con Kolivas patch + inotify patch
libc: 2.3.5-3
