And I would just said one word about my experimental implementation here :

Since i have works hard into canvas implementation, especially to speedup
rendering of image, I have used editor canvas to render preview image on
Preview Mode from Album GUI. It work nice. Now we can zoom in zoom out into
preview. It's fast. This way will solve this B.K.O file :

And Marcel, what news about this one :

http://bugs.kde.org/show_bug.cgi?id=132047

It's can be closed ?

Also, to give an easy comparing tool, Canvas will be the best solution :

http://bugs.kde.org/show_bug.cgi?id=135048

It's easy to do : two canvas instance on the same QMainWindow, with
scroollin synchronized...
