If you've got a postscript file produced by WAVE (I'm using WAVE version 3.10)
- but I think it's the same problem as IDL'ers face since there's a dead
givaway copyright RSI in the PS files that WAVE produces - then what do you
have to take out to turn the PS file into an EPS file? Does the bounding box
assume there's lots of whitespace under the item, ie does the routine that
produces the PS file assume that it's going to be printed on a laser printer?
If it does is there any sure fire way to alter the bounding box?
Is this a FAQ, if so sorry in advance.

PS Does WAVE V4.0 support encapsulated PostScript output? If it doesn't and
it's not easy to turn a .ps file into a .eps file then a future version of
WAVE (or IDL for that matter - if the same problem applies) should support
EPS production.

In IDL, the command to produce an encapsulated postscript file is
DEVICE,/ENCAPSULATED
I presume this command also works in PV-WAVE, since it's been around a long
time. You enter this command after opening the PostScript file, but before
writing any data to it, i.e.
SET_PLOT,'PS'
DEVICE,/ENCAPSULATED
(plotting commands)
DEVICE,/CLOSE
SET_PLOT,'X' (or 'TEK' or 'REGIS' or whatever)
You cannot *change* a PostScript file that already written from regular
(non-encapsulated) to encapsulated formats, or visa-versa. I suppose that it's
theoretically possible, but I don't know how to do it.
The bounding box of an IDL-generated Encapsulated PostScript file puts the
normal amount of whitespace around the plot, i.e. enough to accomodate the
title and axis labels, but not much more.
It sounds like you normally print your PostScript files in portrait mode, which
is the default. IDL does put a lot of space above and below the plot in that
mode (when not writing in encapsulated format). However, you can use the
command
DEVICE,/LANDSCAPE
and the plot will come out turned 90 degrees, and taking up most of the paper.
I believe this command is incompatible with the /ENCAPSULATED switch, however.
