Summary: errors in running giftoppm, ppmtopgm
Keywords: gif giftoppm ppmtopgm mov clouds

I am having some trouble getting the animation of
satellite images to work.  I have obtained the
sun4 code "mov" from David Honig at ics.uci.edu
(thank you David) as well as his script "clouds"
to get the satellite images.  Where I am having
trouble is running the programs "giftoppm" and
"ppmtopgm".  When I try to run these programs I
get the following error message:

unknown relocation type 17Segmentation fault (core dumped)

The man page is less than one page and provides 
no insights.  I am running Openwindows on a Sparc IPX,
using SunOS 4.1.3.  We are not running X windows
so I had to get the giftoppm and ppmtopgm executables
from some X directories buried in our system.  

Any help would be appreciated,

Eric Johnson

P.S. A further quirk of our system is that I do not have
readnews access from my Stanford account.  Please send

Hi,
Someone posted before what the "correct" or "better" coefficients
were for greyscaling images (24-bit RGB).  I have the following:

#define RED_COEFFICIENT    0.299
#define GREEN_COEFFICIENT  0.587
#define BLUE_COEFFICIENT   0.114


Although these seem to work fine, I would be interested in seeing a
better result.

I've gotten several e-mail responses from people who know much more
about this than I do, so I'll summarize a little:

4502 colors is impossible when using 8*10*12 quantization.  Oops.

I found that the choice of grayscale quantizer matters greatly.
Using ppmquant washes out the brighter sections.  I was, in fact,
using djpeg as my quantizer for the gray bands, so I guess it's
not too surprising that the composite image was comparable to
djpeg color quantization.

The effectiveness of a method of color-quantization depends largely
on the image, and somewhat on the observer.  So my test on one or
two images probably isn't worth all that much.

Anyway, thanks for all the responses.

So silk screening does not work like cmyk printing. And you are
overprinting, not using a dot 'screen' at different angles. And
printing colour A on top of B does not give the same result as
printing B on top of A.

You could try - red, green, yellow, blue

Or if you need black for contrast,

red, yellow, blue, black.

in which case ensure that your yellow is on the greenish side of
yellow rather than the orangeish side, and that your blue is on the
turquoise side rather than the purplish side. Or you could use a dark
indigo/purple instead of black.

I suggest you print yellow as the last layer to avoid muddying.

If you are constrained as to the range of colours available to you -
like, only 8 inks in the catalogue - buy some samples and do test runs
with pure colours and overprints.

The technology of CMYK printing makes a lot of assumptions, and these
don't hold for screen printing. Hell, they hardly hold for cmyk
printing ;-)

Let us know how your experiments go

The pnmcat program will concatenate many image files into one image file.  It
has the option to cat them horizontally or vertically.  In case you didn't
know, the pnm utilities operate on any and all of the formats.  You could
use the veritcal options to create columns of images, then use the horizontal
option to cat the columns together.  The size of your images would determine
how many you could get on a page.  Check the man page for more options.

What I am doing is writing an image file translator.
My problem is with the Icon WIndows format.
I have their programmers manual which says Icon can
support multiple images in a file.  I went and got
an Icon image file with multiple images from an ftp site.
I can display this using windows change icon option.

What is wierd is that the first thing in an Icon file
is supposed to be a word reserved to be zero, followed
by a word which should always be one, followed by a word
which specifies the number of icons in the file.  The files
that I looked at don't fit this format at all.  The first word is not zero, or even close, the next two words don't
foloow the specs either.  What's up?  The single image
files I got seem to follow the specs fine.  I can translate
these around, even generate ones myself to display on Win.
however, mulit-images in a file doesn't seem to fit the specs.

any help would be much appreciated.

thanks in advance,
chRis

p.s. this is Windows 3.1 i'm working with.

A script that would do this in perl was posted in either this group or  
in comp.lang.perl or in alt.sources  It was clever enough to read the  
file, make a good guess at the format, convert to pnm format, cat the  
stuff up, and write a postscript output.  Various options for scaling,  
how many you wanted per page and so on.

I assume this is for DOS?  Try FTPing "Image Alchemy"  It'll do anything!
You can get a trial version free by ftp, but have to pay for one which
does files bigger than 640X480.  However, it will support almost ANY format!

Check the archie database for "alchmy16.zip" and you should be able
to get the latest version.

Can the government protect our privacy?  Can it do so without excessive
regulation interfering with how we use our computers and how we conduct
business?   Can it do so when anybody can get a network connection to

Do we want it to try and control these data connections?
