Bitmap scaling isn't provided by Palm OS, so you'll have to implement your
own. There are many algorithms to choose from depending on the speed/quality
tradeoff you want. Here's an article comparing some of the algorithms
commonly used:

If you can arrange for the bitmap scaling to be done on the desktop, you
should. This will make it run faster and I'll bet Windows & MacOS have APIs
for scaling bitmaps! :)
