HELP! Problem with converting pdf to image

[black10dan]

Hello, I am a newbie to IM so I am facing heaps of difficulties. Here is the code I am performing:
convert "test.pdf[1]" test.png

And this is what I get:
Error: /invalidfont in /findfont
Operand stack:

GPL Ghostscript 8.61: Unrecoverable error, exit code 1
convert: Postscript delegate failed `test.pdf'.
convert: missing an image filename `test.png'.

The IM version I am using:
convert -version
Version: ImageMagick 6.2.8 08/15/06 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2006 ImageMagick Studio LLC

And GS version:
gs

GPL Ghostscript 8.61: Cannot open X display `(null)'.

Any ideas? Thanks in advance.

Looks like the ghostscript does not know about or can find the appropriate font requested. Looks like a standard font, so I'd say the ghostscript standard fonts have not been installed.

Problem solved. I had to specify the full path to gs. Thank you.
