I have a problem with the downscaling I hope someone can help me with. The quality I get from downscaling is poor. Except for Supersampling all other resize functions produce similar results. This means that Bicubic looks the same as Nearest neighbor, which is quite bad.
Am I calling these functions incorrectly, or is there a way to get the IPP library to perform a good looking downsample that is not Supersampling?
