A number of years back I was very excited about DJVU and used it to
compress my scanned documents. But at a certain point did I realize that
scanned bitmaps (as well as TeX'd documents width pk fonts) in PDF were
just as small, and I stopped using it, as PDF is much more widely
available. I'm not sure if the almost equal sizes of djvu and postscript
were because bad djvu compressor or because the PDF compressors improved at
some point. I would be interested to hear if someone else has other
experience.
Regards,
Dov

Off topic, but, interesting question anyway.
You can compress pictures taken by your phone.
A shrinking of 2 or 4, or more can be obtained with no visible difference.
You can also collect a set of pictures in a single djvu album.
The viewer (djview) is able to zoom very fast.
Unfortunately neither Djvu nor Jpeg2000 have replaced Jpeg.
Emacs is able to display djvu.
------
To create an album, just do that:
c44 -percent 40 imgp_001.jpg
c44 -percent 40 imgp_002.jpg
c44 -percent 40 imgp_003.jpg
...
djvm -c album.djvu imgp_001.djvu imgp_002.djvu imgp_003.djvu ...
djview album.djvu

OT but I implemented Imagemagick support in Emacs mostly to work with
djvu. The primary benefit over alternatives IMHO is that the algorithm
is free, as far as I can determine. Image coding is a minefield.
