The document compares the 2DBitBlt resampling scaler architecture to other scaling architectures. 2DBitBlt resampling uses a hardware efficient algorithm adapted from image warping with weighted resampling and no power of 2 limitation. It performs anti-aliasing as part of the algorithm and has potential for parallel processing. Charts show 2DBitBlt resampling outperforming polyphase and bicubic scaling in terms of aliasing, while being simpler with a single line buffer. While images may be softer than bicubic, it has advantages of guaranteed anti-aliasing and better performance for higher decimation ranges.
