How create thumbnails?
Posted on 1998-04-26
I have a bunch of scanned photographs, about 600 x 430 pixels in size. In my application I want to create thumbnails for all these pictures and save them to disk in BMP format. How do I transfer/resize the big pictures into thumbnails? I tried using CopyRect from the big image to a small one, but the colors were all mixed up and looked really weird in the small picture, almost like graffiti.
NOTE: I want this done in the background, so reading the form's canvas or anything like that is no good.
