And -- I can't view jp2 images. I guess that I need to download
some more libraries and re-compile some programs.

Hmm ... the only programs which I can find for jp2 (jpeg2000)
have a .exe extension -- and the only source for them is for Windows, so
I'll have to wait a while before I can do anything with these.

This is a nice book/document in highly compressed djvu
format and completely text searchable.

"ddjvu" hits a problem:

======================================================================
ddjvu: [1-15108] Corrupted IFF file (Illegal chunk id).
======================================================================

See if there is anything you can use for viewing djvu from
this page:

http://djvu.sourceforge.net/djview4.html

Hmm ... it is now downloaded, but I need to build two other
packages to go under it:

djvulibre-3.5.21.tar.gz
qt-x11-opensource-src-4.5.0.tar.gz

They mention a binary for Debian towards the bottom of the
page.

A Debian binary will amost certainly be an x86 binary, not much
use on an UltraSPARC III CPU. :-) So, I'm going for the sources instead.

The qt-x11 claims to support Sun's Solaris, so we'll see. Only
the 32-bit version, but the UltraSPARC can run both 32-bit and 64-bit,
with the 64-bit being a bit faster.

Also a link for a Java version over along the left
side.

Hmm ... might be able to use that.

I shied away from the djvu format for years and only
recently became interested. It does a really nice job on old
books if done properly.

When I got it some years ago, it was for some downloaded manuals
for old equipment -- Electronics test equipment, IIRC>

Jpeg 2000 (jp2) files have been around for awhile already. I
know GraphicsMagick has support for it. Seems to me that is
available for Unix type systems.

I don't have GraphicsMagik, but I do have ImageMagick, and it
was one of the ones which I tested on the jp2 files I downloaded. It
simply complained that I did not have a codec for jpeg-2000.

Getting newer software is such a pain when I have to download
and compile a half dozen libraries before I can compile the desired
software. And often, those half dozen libraries need another half dozen
before I can compile *them*.

It might be easier to load them into the OpenBSD systems, which
tend to have a lot of the libraries as pre-compiled packages.

Some info/history and possible sources here:

http://en.wikipedia.org/wiki/JPEG_2000

I stumbled across that while trying to find the libraries which
I needed. Here is the major killer paragraph:

======================================================================
JPEG 2000 has been published as an ISO standard, ISO/IEC 15444. As of
2008, JPEG 2000 is not widely supported in web browsers, and hence is
not generally used on the World Wide Web.
======================================================================

I just found and got the java version as well, so we'll see how
that goes first. If that fails, I may spend a while before attacking
the full compilation sequence, because I'm about to go in for cataract
surgery, and don't know how well I'll be able to work until that is
over. The first one this week, the second about a month later.

O.K. I've still got to compile the qt package to use the
java version. I'm tossing it at the compiler, but if I hit any
problems, it is going to wait until after the surgeries are complete. :-)

I only mentioned the jp2 files to give you an idea of how
much data they are getting from their image taking. I am
curious to look over that data. May just have to suck it up
and download one of the smaller archives sometime and take a
peek inside.

It is a big collection. The zipfile is 239MB in size, and took
a long time to unzip because it created a lot of files. I've blown the
directory of files away for the moment, and will recreate it when I have
something to use on it.

Enjoy,
DoN.
