[Kde-imaging] Kipi plugin

[Dmitry Ashkadov]

Hello!

Unfortunately, IMHO digiKam isn't user-friendly. It has too difficult 
and bulky interface. I can't go to next image because arrow keys doesn't 
work. I can decrease size of image using Ctrl+-, but I can't increase 
its size, because Ctrl++ is Ctrl+Shift+=. I don't really need albums and 
database of images. Settings of JPEG200 encoder from BQM are very poor 
(very strange quality control parameter).

KIPI uses IM. So, only one way remain: IM.

How KDE Applications open jp2 files? Set of applications (kolourpaint, 
okular, gwenview) can open jp2, but all use Jasper. Is it possible to 
make KDE applications using openjpeg?
