Whoa! You've been in the sun too long!

Let's just say that if God meant us to use all that $$ \ | stuff, he
wouldn't have invented FORMAT='(F10.1)'.

I use ghostscript for that. you can find it using google. You can
run it from the command line, or equivalently, spawn a shell command.

A simple version for windows would be:
gswin32c -sDEVICE=png256 -r300 -dBATCH -dNOPAUSE -q
-sOutputFile=output.png input.eps

And this is a snippet from my makefile for making png's from eps's (I
use Cygwin for a bash shell in windows, and good chunks of this code
are due to stuff I found on the web)
bbox=`cat $< | tr '\015' ' ' | head -100 | egrep "^%%BoundingBox" |
head -1 | sed -e 's/%%BoundingBox://g''` ;\
width=`echo $$bbox | awk '{printf("%i\n",$$3)}'` ;\
height=`echo $$bbox | awk '{printf("%i\n",$$4)}'` ;\
$(GS) -sDEVICE=png256 -r300 -dBATCH -dNOPAUSE -q
-dDEVICEWIDTHPOINTS=$$width -dDEVICEHEIGHTPOINTS=$$height
-sOutputFile=$@ $<

Hope this helps,

Mirko

This doesn't seem all that environmentally friendly to
me, but if you *really* need it, you can draw all your
plots in FSC_Window, rather than in normal windows.
Then you can output to JPEG, PNG, TIFF, BMP, PICT and
PostScript files with a push of a button.

IDL> fsc_window, 'plot', findgen(11)

Find the required files here:

Cheers,

David

Nope, just in my cube :-). But you really should not look too harshly
at the code above. It is only programming, just of a different
flavor.

Assuming God invented Fortran of course? (and we *don't* want to go
there!!!!) !-)
