MS> Using 10.6.2 and gs 8.70, when I double-click on the .ps, it comes up in preview (no error message) as a blank box at the top of the page, and Adobe Distiller produces the same outcome. However, ps2pdf (a small front-end to gs writing to the pdfwrite device) produces both the box and several lines of text, with no error message.

Here the file «scratch.ps» opens without complaint with a GhostScript viewer. What I see is a text box with an outline and a drop shadow. Within the box, the text is

*scratch*                              * 1/1*

The first line appears to be rendered by Helvetica-Bold and the second by plain Helvetica.

The text box is followed by some vertical whitespace and then three lines of text, in red, and each line begins


The three lines of text appear to be rendered using a monospaced font like Courier.

I'm not on a Mac machine and don't know that much about PostScript. However, the 'Creator' of the document is «ps-print v7.3.50» and perhaps that has something to do with readability.

Since this list allows attachments, I've attached a JPEG version of what is visible. I've only clipped the top of the page as the remainder is blank. Also, what I see is the same as what John McChesney-Young posted at


Anyway, since it opens without complaint via a simple PostScript viewer, there should be no fault with the file in terms of PostScript code. Of course, maybe the file is supposed to reveal something other than what the JPEG shows.  :-)
