ghostscript fonts

Question

I'm trying to get ghostscript to render a pdf file from a Windows box. The pdf file uses the ComicSansMS font. I've copied the comic.ttf file from my Windows7 box into my /usr/share/ghostscript/fonts directory, and I've created a Fontmap file in that same directory containing this line:

/ComicSansMS (comic.ttf) ;

As nearly as I can tell, the font is not being found despite this. The text comes out very poorly, and some of the smaller font sizes are rendered half the size they should be. Access times and strace show that the Fontmap file is being read, but the font file (comic.ttf) is not being accessed at all. There are no error messages:

If I use -dFAPIDEBUG on the gs command line, I see the following:

Naturally, the line from the above that most concerns me is this one:

"gs -h" shows that the font directory is, indeed, in the search path:

hope 77$ gs -h
GPL Ghostscript  9.00 (2010-09-14)
    [ ... ]
Search path:
   /usr/share/ghostscript/9.00/Resource/Init :

   /usr/share/ghostscript/9.00/Resource/Font :
   /usr/share/ghostscript/fonts : /usr/share/fonts/Type1 : /usr/share/fonts

I've tried several permutations of formatting in the Fontmap file, including:

(Comic Sans MS) (comic.ttf) ;
(ComicSansMS) (comic.ttf) ;
/Comic Sans MS (comic.ttf) ;
/ComicSansMS /comic.ttf ;

I'm fairly sure my original one is the correct one, but I was getting desperate. :-P

Any help would be greatly appreciated. Thanks in advance.

Answer 1

I came back to this problem after a delay. Upon further investigation with a magnifying glass, the problem is different from what I initially thought.

Text is definitely being rendered incorrectly in parts of the document. Each letter is far too small, though the spacing is oddly correct. However, the individual letters are the correct shape for the font.

The font on disk is not being accessed, but that's because the fonts are all embedded within the document. This fact would probably have been obvious to a Ghostscript expert from the output I posted in the original question (I'm guessing the "HYLUQF+" prefix is the smoking gun there), but I don't work with Ghostscript much. My fonts were installed correctly, and other documents were able to access them without trouble.

Of course, this still leaves the question of why my embedded fonts are being rendered incorrectly, but I will investigate that separately and/or post a different question. I maintain that the PDF file is uncorrupted (I have several other PDFs which exhibit the same problem), but I still don't know what's wrong.

@pipitas: Thanks very much for trying. You certainly did help verify that my installed fonts are not the problem. Actually, now that I look again, you even gently suggested the font might be embedded, but I either didn't see it, didn't believe it, or didn't know how to check.

Answer 2

I assume that PDF does not have the ComicSansMS font embedded?

You should consider 2 other possibilities as well:

1. Your PDF file card-01.pdf is somehow corrupted. (Are other PDF viewers rendering that file without a problem? Does it display OK in Acrobat Reader on Widnows?)
2. Your fontfile comic.ttf is somehow corrupted. (Which method did you use to transfer it from Windows to Linux?)

You could try to positively proof that both these components are getting along well enough with each other by using Ghostscript+comic.ttf to create a PDF (with comic.ttf embedded):

gs \
  -sFONTPATH=/usr/share/ghostscript/fonts \
  -o comic-ttf.pdf \
  -sDEVICE=pdfwrite \
  -g5950x8420 \
  -c "200 700 moveto" \
  -c "/ComicSansMS findfont 60 scalefont setfont" \
  -c "(comic.ttf) show showpage"

On Windows, use this variation of above command:

gswin32c.exe ^
  -o comic-ttf.pdf ^
  -sDEVICE=pdfwrite ^
  -sFONTPATH=c:/windows/fonts ^
  -g5950x8420 ^
  -c "200 700 moveto" ^
  -c "/ComicSansMS findfont 60 scalefont setfont" ^
  -c "(comic.ttf) show showpage"

When I do this, I see:

gswin32c.exe ^
   -o comic-ttf.pdf ^
   -sDEVICE=pdfwrite ^
   -sFONTPATH=c:/windows/fonts ^
   -dHaveTrueTypes=true ^
   -g5950x8420 ^
   -c "200 700 moveto" ^
   -c "/ComicSansMS findfont 60 scalefont setfont" ^
   -c "(comic.ttf) show showpage"

and my output PDF comic-ttf.pdf looks OK and does have the comic.ttf font embedded.

If this does also work for you, then your Ghostscript and your comic.ttf are OK, but your PDF file cards-01.pdf is not.
