I have a question about Gimp's lanczos3 image resizer.
I found that the results enlarged by Gimp lanczos3 resizer look very
different from other implementations' such as ImageMagick. I tried
implementing simple (no optimizations) lanczos3 resizer, it generates
the same results as ImageMagick.
Gimp's one looks much better for me because of its less jaggies.
Does Gimp's resizer do something special?
