I recently added two recommandations for improvement of MediaViewer here:
https://www.mediawiki.org/wiki/Multimedia/Media_Viewer#Recommendations_for_…
These my pretty exotic requests listed into "Bugs" section (I don't know if
I posted them into the right section):
* While supporting multiple page djvu, to implement a tool to copy into
clipboard with a click from displayed djvu page: (1) pure text layer, (2)
lisp-like mapped text layer structure at line or word detail, (3) xml
mapped text-layer (Alex brollo)
* While supporting multiple page djvu, to implement a tool to crop and
download illustrations (as jpg or png) from image djvu layer of current
page (Alex brollo)
The access to those two tools could enhance a lot, IMHO, full usability of
data wrapped into our beloved djvu files. Some js tool could manage mapped
djvu text with interesting results. Many from us can get the same data by a
local djvuLibre application, but getting data from MediaViewer could avoid
the use of local command-line applications and make easier access to those
interesting, so far unused data for anyone.
