if you can drop 9x support you can use SetgraphicsMode and XForms.

I think I've heard before that PlgBlt() being used to rotate images. I've never tried it myself tough.

If, however, you want to combine rotation with another transformation, there's a good chance you'll need to roll your own routine.
