Hi there (sorry for the cross-posting),
I have some eps plot (done with IDL, some of them in colours) that are
far too big.
I should upload them on online archive server and I have to resize
them. I have tried something like the following command (I'm using
linux)
gs -r300 -dEPSCrop -dTextAlphaBits=4 -sDEVICE=png16m
-sOutputFile=fig.png -dBATCH -dNOPAUSE fig.eps
but it does not work.
I was wondering if there's any tip or trick to reduce the size of the
eps file to be used in a latex file.
I have opened the eps file with text editor and canceled the %% lines.
That reduce the size of almost nothing :(
Apparently IDL is clever and there aren't any redundant fonts ...
I would also be interested in know if there's any command to give IDL
in order to produce file with lower dimension (maybe a good compromise
between quality and size...)
Thanks a lot!
s.

I have successfully used basically that exact same command line, only
I used -sDEVICE=jpeg instead of png16m. Not sure if that would make a
difference or not.
I presume this is for arxiv.org, in which case you may want to check out
the automated arxiv submission preparation script I wrote a while ago:
http://astro.berkeley.edu/~mperrin/submit_prepare.pl
It takes a LaTeX file and automatically compresses all the EPS files
included from that LaTeX file, then tars up the whole bunch for
easy upload. But then again, if the above command line isn't working
for you, I don't know why my script would be more successful, since
that's what it does internally.

Ah, a documentation problem, I found it in the list of all DEVICE keywords, but
it is not in the list of keywords accepted by the PostScript device. :-(
I see that this has not fixed the limitation on 24-bit color plots (24-bit color
for images only). Too bad. I waste more time working around that than any
other IDL problem I can think of.

I've got it on 6.2, but had to search for it. It's not listed in the
index.

Instead of doing trial and error ad ibnfinitum, please post (an URL to) a
sample file so that we can have a look into it and possibly make
a proposal on that experience.

Do you have the "convert" command on your linux machine? Most modern
Linuces do have it. I think it is part of the ImageMagick package.
Usually this command,
convert fig.eps fig.png
will do the trick, and then you can futz with the output size (-size)
if you need to. For a preprint server, the quality only needs to be
good enough to be legible, not perfect for publication, so you can
usually scale down the output image.
Sometimes when I do things by hand, I open the PS figure in ghostview,
and then capture and save it using "xv".
Good luck!

I'm on 6.3, but I think it was present in 6.1 already (never used
anything before 6.1).
