Hello,

I am trying to get proper command for scaling down of big images for
internet purposes. I have something like:

convert p1010013.tiff \
    -quality 100 -sampling-factor 1x1 -resize 80% -unsharp 30x1+0.5 \
    -quality 100 -sampling-factor 1x1 -resize 50% -unsharp 30x1+0.5 \
    -quality 80 -sampling-factor 1x1 -resize 50% -unsharp 30x1+0.5 p70.jpg

Two questions:

1. Any hints on unsharp values?
2. Has declaring of quality and sampling-factor before each resize any
   sense? I didn't spot difference but I put it 'just in case'.

m. 

ps. There is also colorspace and density stuff but I'd like to
    concentrate on unsharping question :)
