Patrick,

Qimage way is wrong, because it do not support 16 bits color depth image.

To handle PNG and TIFF, 2 image loader need to be written to not use
ImageMagick. Image writter are already done using libtiff and libpng :

Take a look to digiKam core, which have already this code. Of course,
kipi-plugins don't need a complex loader like this...
