Paul,

Thank you for this excellent reference!
I've added it to my library, and also a free
program called "WinDjView" to view it with.
It's available from SourceForge at:
http://prdownloads.sourceforge.net/windjview/WinDjView-0.4.1.exe?download

Has anyone yet solved the problem Brown
found, of the inharmonic fundamentals on
bowed strings? That's an unexpected and
odd result.

Regards,
Yahya

It would be better to cite the home page...
But it seems that sourceforge is in mantainance just now...

Hudson, meet DjVu. It's a multi-layer document format based on a
suite of image codecs, including advanced wavelet-based encoders
developed at AT&T labs. Lizardtech now owns those, and distributes
a free, lightweight browser plugin that makes Acrobat look more
like 'Jimbo the lumbering Giant: oddity of the West'.

http://lizardtech.com/download/dl_options.php?page=plugins

Meanwhile, the opensource version is here:

http://djvulibre.djvuzone.org/

The lack of a vector layer (postscript) and the addition of jpeg2000
to PDF means DjVu is probably never going to compete with the latter.
However, in my experiments I have never been able to get scans as
small with PDF, even with jpeg2000, as I can with DjVu (I use
any2djvu:

http://any2djvu.djvuzone.org/

)

I've never seen it before :-)

I installed `djview' (and other stuff) from Debian 3.0 today. It is still missing the GhostScript driver -- without it, I cannot convert `any to djvu'.

Thanks, Carl.
