The PowerDraw pre-release 3 had no pixel level collision detection, since Object Engine wasn't fully functional. What's more, it's Object Engine had sneaky bugs (whoops! ). Right now I'm rewriting a game, Humberto Andrade made to make it easy-to-read and it uses Object Engine... and yes, the version I'm going to release soon (PowerDraw 3.0 full) has pixel level collision detection. I could release PowerDraw pre-release 4 about a week ago with fixed Object Engine and some Software Renderer fixes, but I'd rather focus on making final version. Also, I've seen a tutorial on pixel level detection in PowerDraw, here on DGDev in Tutorials section - you might take a look (although there's a lot of code).
