To be fair, DjVu lossy-encodes the graphics, not the text. One of the "selling
points" of the format is that B&W text is kept on its own lossless layer.
Also, G4 coding is a much better known standard. If
fifty years from
now someone has to build their own drive to read an ancient CD, and
discovers that it's full of compressed images, I think they've got a
much better chance of being able to decode G4 images since the format
is well-documented and well-known.
Agreed.
However, if someone else went to the trouble of
archiving a bunch of
old computer docs in DjVu, I'd still thank them for doing so, as it
is quite obviously much better to have the docs in DjVu format that
to not have them at all.
Heh, also agreed :-)
