[magick-users] Best ways to decrease size of image

[Mikolaj Machowski]

Hello,

Anthony on his incomparable pages writes very much about increasing size
of image and how to get the best results but relatively little about
decreasing size.

What is the best way(s) to achieve that?

To get decent results when doing transition from 4000x4000 tiff to
1000x1000 jpg I am doing something like that:

convert pic.tiff -depth 8 -density 72 -resize 1000x1000 -filter lanczos
-unsharp 1x1+0.6 -sampling-factor 1x1 -quality 90 pic.jpg

If I want better result I can make it in two or three steps and
manipulation unsharp mask. Any ideas how to do it better?
