Cannot view image in PostScript File

This is my first time working with PostScript files. There is an image that I would like to view but when I open it with GSView a window comes up with the following error:

Error: /nocurrentpoint in --currentpoint--
Operand stack:

Execution stack:
   %interp_exit   .runexec2   --nostringval--   --nostringval--   --nostringval--   2   %stopped_push   --nostringval--   --nostringval--   false   1   %stopped_push   1983   1   3   %oparray_pop   1982   1   3   %oparray_pop   1966   1   3   %oparray_pop   1852   1   3   %oparray_pop   --nostringval--   %errorexec_pop   .runexec2   --nostringval--   --nostringval--   --nostringval--   2   %stopped_push   --nostringval--

When I open it on my Mac with Preview, it also gives me an error that it is not able to open because it isn't able to convert to PDF.

How can I view the image?

Without seeing the actual PostScript program its hard to say exactly what the problem is, however nocurrentpoint is quite a specific error, it means you haven't specified an initial location before attempting to draw something.

But I notice that the 'offending input' begins with gsave currentpoint, that will also give you an error if you haven't already specified an initial point.

Try putting 0 0 moveto earlier in the program (you might also try 100 100 moveto, the PostScript co-ordinate system has 0,0 at the bottom left).

I imagine the 'distiller' application on the Mac is encountering the same error when interpreting the PostScript, which is why it can't convert it to a PDF file.
