Re: Lanczos interpolation

Lanczos is an alogorithm that seems to work well when trying to raise the size 
of an image. Other sources are Fred Mirandas Bicubic stepping action, Genuine 
Fractals, S spline and a few others. I use what folks say works and Lanczos is 
one of those since I make LF prints. Have never heard of Hamming or Hanning 
what was your source? Just curious.
