Summary: postscript eps file error

Initial Comment:
use of standard eps file generation, as in:

(%i2) plot2d( sin(x),[x,-%pi, %pi] ,[gnuplot_term,ps],
           [gnuplot_out_file,"c:/work2/test2.eps" ] ) $
Output file "c:/work2/test2.eps".

results in the generation of test2.eps which is 2kb and contains no plot instructions. The end of the file has an apparent error message(? I am no expert in postscript language ):

...
/hpt hpt_ def
/vpt vpt_ def
Level1 {} {
/SDict 10 dict def
systemdict /pdfmark known not {
  userdict /pdfmark systemdict /cleartomark get put
} if
SDict begin [
  /Title (c:/work2/test2.eps)
  /Subject (gnuplot plot)
  /Creator (gnuplot 4.2 patchlevel 0)
  /Author (Edwin Woollett)
%  /Producer (gnuplot)
%  /Keywords ()
  /CreationDate (Wed Jun 06 10:38:32 2007)
  /DOCINFO pdfmark
end
} ifelse

When viewed with gsview32, there in no plot. Direct use of wguplot32 software results in a file of size about 14 kb.

This error observed with both v 5.11.xx and 5.12:
My build info:
Maxima version: 5.12.0
Maxima build date: 19:33 5/3/2007
host type: i686-pc-mingw32

Tested w/ 5.14.0 on Windows Vista, problem not observed (complete
Postscript file output). Closing this report as fixed.

Back from vacation! I have used the file prologue.ps, placing it in the
directory structure suggested, on my computer a rather long path name:
c:\Program Files\Maxima5.12.0\bin\share\PostScript\prologue.ps
Maxima now correctly creates the eps file.
Thanks.

>From what I can tell, the Maxima 5.12.0 Windows installation is missing a
file that Gnuplot wants, namely prologue.ps. I've taken the liberty of
attaching the prologue.ps from Gnuplot 4.2 to this report. That file should
be copied to ...\Maxima-5.12.0\bin\share\PostScript\prologue.ps in the
Maxima installation. 

Please give that a try and let us know how it turns out.

File Added: prologue.ps

I observed this eps file bug on my Win XP box and using Maxima 5.11.99 and
5.12.0

A milder version appears in ver 5.9.3 in which Maxima complained but
produced a viewable plot as viewed with gsview32. The 5.9.3 complaint looks
like:

Maxima 5.9.3 http://maxima.sourceforge.net
Using Lisp GNU Common Lisp (GCL) GCL 2.6.7 (aka GCL)

(%i1) plot2d( sin(x),[x,-%pi, %pi] ,[gnuplot_term,ps],
           [gnuplot_out_file,"c:/work2/test6.eps" ] ) $
'ghostview' is not recognized as an internal or external command,
operable program or batch file.
Output file "c:/work2/test6.eps".

Same error observed on my Win XP box + Maxima 5.12.0.

However it works as expected with Maxima 5.11.0 on same Win XP box, and
with Maxima 5.12.0 on Linux.
