Does this have a stretching tool?
Icon Master does not. It has a Clone tool, which is very handy for creating quick duplicates of other things you have on the canvas (that's how I made my Lemmings more easily and quickly). But no scaling/stretching.
I looked into it in the past, and you can
create icons in DeluxePaint. But it would be a total headache to do what you're wanting to do. Because you'd have to import the files (or more likely create from scratch). Then, you use an icon converter script to change the IFF to an icon (info) file. From there, due to the colors likely getting goofed, you could open them up in IM and fix things properly. But at that stage.. I mean I don't know. But at the same time, have really enjoyed using this kind of software and stepping away from games for a while. There such a vast sea to explore - as you know - outside of just gaming.
I may screw around icon creation with DP just to check it out. I'd love to import some imagery from stills taken from Flash Gordon for two of my drives. And go from there. A hard drive icon of Max Von Sydow's head as Ming? And if you click, his eyebrow raises menacingly? I mean come on now.
