<![CDATA[AnimatedImage - unable to read MNG files]]>Hi,

I'd like to use MNG files (animated PNG) to display in an AnimatedImage element. This used to work flawlessly before, but I have installed a newer version of Kubuntu Linux in the meantime and whenever I try now the error 'Error Reading Animated Image File' appears. Animated gif files work fine.

Works fine now.

As an alternative, you can also get Qt 5 sources and only build the mng plugin

/usr/lib/i386-linux-gnu/qt4/plugins/imageformats/libqmng.so

This file is not present under the qt5 folder, I tried copying it and then recompiling my project but it still gives me the same error.

There's also a qt5 imageformats package for my distribution but unfortunately not my specific revision (13.04 raring ringtail), I'm guessing the repository has some catching up to do. Thanks for the tip

I'm using QtCreator 2.7.1 with Qt 5.0.2 that comes with the Ubuntu SDK package. I'm not keen on installing the official Qt distribution on top of that.

Did you rebuild your application from scratch after the update ?
