Hello everyone, I just need a hint of where to start from. I need to implement hardware accelerated zooming in feature with dithering. What kind of API/interface should I use? Thanks ahead for your advices.

Jus about the only way to do hardware accelerated anything with bitmaps requires rendering a textured quad and using the bitmap as the texture with a 3D rendering API such as the Direct3D component of DirectX or openGl.

Thank you. I have tried StretchBlt() but my results aren't smooth enough for enlarging.

If I will go ahead with Direct3D will I find support for high-quality resizing algorithms like precise bicubic resampling?
