GhostScript Error

Question

In a specific PDF file when you run the following command:

gs -dSAFER -dBATCH -dNOPAUSE -dQUIET -dFirstPage=1 -dLastPage=1 -sDEVICE=pdfwrite -sOutputFile=output.pdf input.pdf

I get this error:

GPL Ghostscript 8.71: Warning: 'loca' length 188 is greater than numGlyphs 93 in the font MGOXZX+Arial-BoldMT.

Any ideas what this error means and how to solve the problem?

Answer 1

First, Ghostscript did not declare this as an “error,” but a “warning.” This is a pretty big difference.

Secondly, you asked Ghostscript to display the first page of input in PDF format. Did it work? Do you see any visible differences when comparing output.pdf and the first page of input.pdf?

Third, if there is really a problem, you should indicate which version of Ghostscript you are using. the most recent of them is 8.71 .
