I have made a UNIRAS hdf-driver, which you can get for free. The beauty 
with hdf is, that you can use UNIRAS to make many (20-40) pictures in
one hdf-file, and with AVS you can show this multi-picture-file, and
you can even make fast animations from the Xserver by storing pixmaps
one-by-one i the Xserver-memory. UNIRAS makes very nice pictures
with axes, notes, colors.

The hdf-driver uses NCSA libaries, but i can also offer you a targa-driver,
which we use to make real movies from a PC with targa-card and video.

If you must have AVS image-file (.x) then the hdf/targa-driver should be easy
to rewrite (you get a 640x480 rasterimage with a 8 bit lookup-table)
or you can convert hdf/targa-pictures with a suitable conversion-package
as "San Diego Image Tools" or the like.

While looking for other things in the avs (flow and sim) libraries, I noticed
a routine AVSSet_background_proc, anyone heard of this?
(I did not see it in the developers guide.)  Is it a real feature that will stick around
in later AVS's?
I tried to use setup a routine with that for a coroutine and a subroutine but the
backround proc never got called.
What does it do?

Paintshop Pro is a shareware program available on ftp.cica.indiana.edu in the
directory pub/pc/win3/"SOMETHING" (check the INDEX file in pub/pc/win3)

This program can read and write .WPG files as well as about 15 other formats.
It can be used to convert .WPG files to/from .BMP files. It can also be used
by reading in a .WPG file, then using CUT/PASTE via the clipboard to transfer
the image to another application. It has many other features as well.

I had this problem also when I tried to run the POV version I had gotten from .carleton
I spoke to Aaron Collins about the error and we did a diff of the parser that
I had FTPed versus his version on the BBS, they were different! .  The problem
was solved by using the BBS version.

Yes, there is a need for an FAQ. Many Q's are FA nowadays ;-)

It was last updated in December last year. Its nearly August. The
information needs checked and revised. Anyway, it reflected the interests
of the person who used to post it, and no-one wants to risk wrath by
posting or editing the old FAQ. Last person to post it got flamed.

The ruffling looks like permanent. And reposting would just rub salt into
the wound.


How about we make a new FAQ, by consensus?

If anyone archives the group, it would be interesting to see which
questions have been asked, say, 3+ times in the past 6 months or so. 

Then once we have a workable set of questions, people could post
answers/collect the answers that were posted, according to interest and
expertise. We could kick the answers around, discuss them a bit on the net,
then collect the lot into a file and stick it on some freindly FTP site and
ina cron job somewhere.

Well?

Hello there:

I would like to know any good books, papers, and algorithms about 
color image processing, particularly color segmentation, leveling, 
thresholding, color to grayscale (bitmap) conversion, and 
color representation (RGB, CMY, etc.) which is less computational
expensive. I highly appreciate any information, recommendation,

This may be in the FAQ, but I don't have a copy handy right now, so I
appologize in advance if this is a FAQ. What I am interested in is in
displaying 24 bit images on a DECStation 5000/240 running Ultrix 4.2A
with their full 24 bits.  I am aware of XV 2.21 and Xloadimage, but
they both appear to first convert to 8 bits.  I was wondering what
were the best/fastest public domain programs to display such images,
and sequences of such images in rapid succession.

Thanks for any info.

The Hough transform is relative of a class of transforms called the generalized
Radon transforms.  These map information from one coordinate domain to another
by integration of some of the data.  There is much material on these transforms
and their inversion in the medical tomography and geophysics literature.

I don't know if there is an exact inverse (reversal), but there are near
perfect inverses for practical purposes. The reason there doesn't seem to be
an inverse is because even parameterization in one coordinate domain usually
undersamples or oversamples some even part of the transform coordinate domain.

Tanya,
        There is a DOS program called Graphic Workshop available via
anonymous ftp from wuarchive.wustl.edu in the mirrors/msdos/graphics
directory in a .zip file called grfwk61m.zip that does a fairly good job and
can directly convert the above files easily, as well as several other formats.

Hope it can help.

It's rather difficult to get a program to do tweening.  Most computer
programs can only do linear interpolation between frames, which is
NOT tweening--it is morphing.  Morphed motion, while occasionally
desirable, is usually not, for animation purposes.

For instance, take an animation of someone walking.  When you
walk, your leg moves forward quickly, slows as you step on it,
reverses direction, gaining speed until you bring it back again.
If you do simple interpolation, it'll look wierd...very robotic.

There is a program out now for IBM PC's that allows you control over
the morphing, so you _can_ get tweening results (specifically,
it allows you to control the rate of change between individual 
frames).

Email me if you want more info.
