ok, i know how to do you.

yes, i found scanned images are usually noisy than digitial camera's.

i do the noise reducing using despeckle filter. but it was adviced in
many other articles that tools like despeckle will also introduce
blurring ( i found it's really true ) and should be down in the very
final step, especially after downscaling or upscaling. so, i think i
have some problem to get your point here. did you really suggest i do
the despeckle or some unsharp mask things before downscaling ?

supposing my Gimp has already equiped a Lanczos interpolation, when
comparing to imagemagic in scaling, which one performs better in term
