Call for international participation in new art/science project.
KNOWBOTIC RESEARCH
Simulation Room -Mosaic of Mobile Sound Data
Hamburg, 5.2 - 20.2.93
We will be showing a VR installation in February at
the MEDIALE93 - Festival for Media Arts and Media Future - in
Hamburg, Germany. The installation, housed in the freight ship Cap
San Diego in Hamburg - harbour, has three main areas.
Section one is a sophisticated, walk - in data - base  utilising a
collection of sound samples from around the world, which will be
used to produce a virtual 'sound room'.  The sound data will
correspond to the second section,  a physical room, where visitors
will be able to navigate through the space with the aid of a mobile
ultrasonic sensor and an artificial eye display and activate the data 
to a realtime-concert.
The action of the visitors, within  this 'virtual organism,' will be
displayedon a video screen shown in a control room area (the third
area).
We welcome your participation for the international sound - data -
base: To participate in this international project we need from you a
6 second long sound sample, a cultural statement, reflecting
your personal attitude towards the "world". Please send this via
email or ftp. (aiff, wave, next formats)
All participants and institutions will be credited in a publicly
displayed database during the exhibition.

I know it is obnoxious when people post pure drivel, but ut can be just as bad
when they post overly large files.. I know someone on this list is a netted BBS
sysop who has to pay for the large band width net feeds.. Am I eing wrong for
asking that people post soem example of thier work and a site where they can
get a copy.. OR someway to email request it.. 

What does all you all think about this idea??

How about because the thoughtlessness of posting something to a group
without reading what has been posted recently was so overwhelming there's
not much to be grateful for... There are THREE unexpired copies I can
read in the news at my site already. And because the text is large, and
multiple copies being transmitted across the world are a huge resource
waste.

Come on, this is common sense. I hate the net.police thing, but every

I was concerned about the standardization of JPEG
between two programs I have, so I did some tests.

The original file was a 24-bit true-color file of
size 768 x 768 at 300 dpi, scanned into PhotoStyler.
I saved the file in two formats: 24-bit Targa and
24-bit BMP.

To ensure that both files had the same color
information, I checked the number of unique colors
using Paint Shop Pro. Both TGA and BMP files reported
having 167510 colors.

Then I compressed them using ColorView 2.0 for DOS
and WinJPEG 1.6. (The reason why I used a quality of
74 and 76 for Colorview was because it did not
offer 75 as an option; so I also used those settings
for WinJPEG.) Also, Cview only accepts BMP files.

Original   Software   Quality   Entropy   File
  File       Used     Setting   Optmztn   Size
------------------------------------------------
  TGA      WinJPEG      75        Yes     135909
  BMP      WinJPEG      75        Yes     136256

  BMP      Cview        74        N/A      81795
  BMP      Cview        76        N/A      84487

  TGA      WinJPEG      74        Yes     133183
  BMP      WinJPEG      74        Yes     133519

  TGA      WinJPEG      76        Yes     141489
  BMP      WinJPEG      76        Yes     141800

  TGA      WinJPEG      74        No      143693
  BMP      WinJPEG      74        No      143693


I am very confused by WinJPEG's method of saving JPG's.
WinJPEG takes two original files of the same content but
different format, yet outputs JPEG files of different sizes
(with entropy optimization on).

Cview's JPEG output is much smaller than those of WinJPEG
for a given Quality.

My questions are:

Which program adheres closer to the Quality settings
described in the JPEG FAQ?

Exactly what is entropy optimization and how does it affect
the quality of the compressed image? (Should it be used if
I want a "standard" Q75 JPEG file?)

And for those who have PhotoStyler 1.1a: how does the
quality range in the JPEG export module translate to the
quality range described in the FAQ? (PhotoStyler uses
a range from 0 to 100, with 0 being minimal compression,
100 maximum - just the opposite of convention). What
the heck is the difference between YUV422 and YUV411
SubSampling?

Sorry to ask so many questions, I'm just very confused.
Thanks for any info.

Pgmtopbm uses floyd-steinberg dithering by default.  You want thresholding.
Change the call from "pgmtopbm" to "pgmtopbm -threshold -value 0.1", and
try it out.  The "-value" flag sets the level of the threshold: 0.1 means
values above 0.1 get set to white.

we have a demo copy of coreldraw for unix that we received a couple
of months ago and the problem is that coreldraw for unix is still
coreldraw 2.0.  i think you are speaking about the photopaint
program, which is part of coreldraw 3.0.

(if corel has released coreldraw 3.0 for unix then never mind!)

by the way, i found the print capability of coreldraw for unix extremely 
lacking.

Scitex CT2T:

No header, number of tape blocks is height of image, bytes per block

0 = 0% dot, 255 = 100% dot (If I remember correctly).

I have some of these jpeg files, that djpeg can't handle and Alchemy 1.4

Subject: RFI: auto create raster file from raster "segments"?

I have a graphical problem and am looking for a solution.

Brief statement of problem:

I need to take the output of a user display prgram running
under X and make it available for display in an propriatary
X-based presentation program (kind of like a Freeland for X).

This would be easy if I could use xwd to dump the screen,
convert the dump to GIF, crop the gif file, an import the
GIF file into the presentation system (as a "slide").

The problem is this problem has to be automatic: It has to
happen in the backgroup. The user program may not even be
up and running at the time and the specific screen is 
nested within another program.

The original display is made of colored icons, fonts and cells and
is driven from d fixed-length, but variable data, text file.

Potential solutions?

I have access to the same data file information. 

One way I guess
would be to create a composite graphical file using a programable
vector language like postscript based on the variable data, and
import the result as an EPS file or convert to a raster file.

Another would be to have a bunch of raster "segments" or icons that could
somehow be concatinated to form a single composit raster file
(GIF, TIF, etc.). But, this has to be done programatically.

Any suggestions or pointers (programs on the net, code fragments, etc.)?
