A djvu file is the wrong file type to be extracting an image, it is a
jpg, and we all are aware of the lossy issues with jpgs and playing
with those as images. There are better file types to be using to base
an image, and
archive.org has those available, so something that
allowed easy extraction better quality images would be better.
Personally I still use the
archive.org image viewer, expand it to the
largest size, and then right click to save the image from the browser.
Pulling apart a djvu file into text and image is also destroying what
is integral to a djvu file.
An online cropping tool from a djvu would be interesting, and
WinDjView already does that if you have the software. My issue is that
I don't see the advantage of that in MV if we have extracted the work
already, and it isn't hard to do it if it hasn't been extracted.

I recently added two recommandations for improvement of MediaViewer here:

These my pretty exotic requests listed into "Bugs" section (I don't know

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.
