[bug-gs] Re: Ghostscript with matlab |

[Ray Johnston]

Peter,

You are probably better off working through the Matlab support
and/or groups.

I don't really know much about Matlab, but AFAIK, it exports
EPS and PostScript from the 'print' function (I referred to
http://www.mathworks.com/support/tech-notes/1100/1102.html)

It appears that some tool is sending invalid PostScript to
Ghostscript, possibly due to missing a PS ProcSet. The
error message "/undefined in Invalid" would be expected if
a file contained a token "Invalid" since this is not a
valid PostScript operator or predefined element.

In order for me to tell more, I'd need to see the PostScript
that is being fed to Ghostscript.

I am curious about the invocation of Ghostscript from Matlab --
is Ghostscript part of the standard Matlab distribution ?

Regards,
Ray Johnston
