Hi Michel,

IMSB.Graphic.Draw( X, Y, Graphic ) returns an error:

"Incompatible Types: TCanvas and Integer"

Ok, I'll try to explain what I want to do. I have two Tiff-images. I load the first image into an ImageScrollbox, then I want to copy the second(smaller) into a region of the first one. And all that without using the mouse (or even ImageScrollbox if that is possible).

Thanks in advance
Paul
