Nope, at least not with the libs.

You can copy pixels between video ram and main ram using LoadImage and
StoreImage then access the pixel data in main ram but doing it this way
means that by the time you access the pixels in main ram two frames have
already passed.

Check the faq or collision detection threads for ways to do pixel perfect
collision detection.
