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 Le 31/05/2015 12:41, Martin Schöön a écrit : > Anyone using djvu? > http://en.wikipedia.org/wiki/DjVu > http://www.djvu.org/ > > Just curious. > > -- > Martin Schöön > > http://hem.bredband.net/b262106/index.html
