Open format?

With patents? It might be a good idea to mention that in case anyone reading this article is thinking of adopting the format. For a user it makes little difference since they can just use the free viewers (even Irfanview can show them), but for people wanting to write encoder/decoder support into their own (commercial) software this is a very big deal. This effectively makes it no more or less open a format than PDF or Postscript. 71.196.246.113 (talk) 15:31, 9 February 2013 (UTC)[reply]

What patents? DjVu is generally considered an open format and has very good free software tools for producing it, although not as good as some commercial ones by the original producers. I've not investigated but I've always thought this was just about software source and licenses rather than patents? It would be very nice if you could add more references.

In case that page disappears, I put the list of numbers here. 71.196.246.113 (talk) 08:47, 22 February 2013 (UTC)[reply]

broken link

The second external link at the bottom of the page is broken. Maybe it should be http://djvulibre.sourceforge.net/ but I am not sure. — Preceding unsigned comment added by 2001:6B0:E:2018:0:0:0:207 (talk) 15:47, 12 February 2013 (UTC)[reply]
