Re: Can't save a plot

[Jorgen Sandberg]

Dear Ben Abbott,

Maybe this info can help clarifying the problem.

I have added to the octaverc file an fprintf of the path before and after 
the addition of the path to the gswin64. The print shows that the correct 
folder is added to the path.

To verify the path is indeed there I have entered at the command prompt of 
OCTAVE   system("gswin64.exe") and ghostscript starts up. Thus it is in the 
path.

Why does it not start when I enter  print -dpdf -Ggswin64.exe test.pdf

Regards,
Jorgen Sandberg

When you installed Ghostscript, what was the "Destination directory"?

DId you set "gs_path" to the "Destination directory" in ~\.octaverc?

Using the default destination directory for 32 bit Win7 the adds to include 
in ~/.octaverc are ...

   cmd_path = getenv ("path");
   gs_path = 'C:\Program Files (x86)\gs\gs9.05';
   if (isempty (strfind (cmd_path, gs_path)))
     setenv ('path', strcat (cmd_path, pathsep (), gs_path));
   endi
