WOW, that was a great speed improvement !
Thanx !

EDIT : I need also to implement ZOOM, PAN and a multipage interface. For PAN, no problem, I can derive from ImageCtrl.
Regarding ZOOM I wonder if there's not a fastest way than rescaling the image on the fly.... Does the main image paint code provide some stuff for resizing image on the fly, maybe with help of native code ?
For the multipage stuff I'll look tomorrow on Raster code.
Ciao
