The Lanczos filter provides an improvement in visual quality as compared to the bilinear filter. It seems to provide more sharpess where sharpness is needed and is not that much slower than the bilinear filter. It runs between 75-80% as fast as the default bilinear filter.

There was a problem hiding this comment.
Is this correct, or is it supposed to be Bilinear (1) is default?

Yes, good catch. My intention was to retain (1) as the default. |
