Can anyone think of a good way of storing pictures in their normal size, but shrinking or enlarging them as they are drawn in blitz 2d?

Not that I know of. The 2D functions basically blit rectangles (or sub-rectangles). To do scaling, you need to move to 3D and use sprites. Unless I missed something in the docs ...

Write your own shrinking/enlarging algorithm if necessary. It's not tough.

Hi Folks, Why not use ScaleImage image,x,y ? Later, Jes

Slooooooooooooooooooooow, that's why. Certainly you don't want to be doing that in a normal render cycle, but only pre-scaling the images and storing them.

I've got some code by someone else that's dead fast (rotate and scale). If I forget to post here later, just mail me!
