Can this feature be used to actually reduce the resolution of scanned

I have large dictionary (15 volumes) scanned as 600 dpi TIFF files, you can
have a look at it in DjVu format at


On some stage of processing I would like to reduce resolution to 400
or 300 dpi, to speed downloading paging for viewing, and also hoping
it will fit on CD instead of DVD. My first idea was ImaMagic
`convert', so I posted a query on ImagicMagic list


I have also posted a similar query on DjVu forum:


To my surprise, I got no constructive answer. Is this task so difficult?

Best regards


P.S. The problem we discussed on the list in June seems to be solved by scanning
the document again by a more careful and better qualified person.
