Re: Difficulty finding a font file through the libraries

[Michael Brennen <michael@xxxxxxxxxx>]

Thanks very much for the response. I had in mind to add that this is on a CentOS 7 system, but was focused on getting other details right and forgot.

The production script runs as apache; there is no local fontconfig directory. I ran the process with sudo -u apache, and it has the same result: the font is found in the .ttf.orig file.

fc-match running as either root or apache finds the font in both files, and it lists the .ttf file first.

The gs output follows; perhaps someone will see something useful.

Querying operating system for font files...

I will be happy to provide other info or run tests as needed. I don’t know how fontconfig relates file names to font names, so I am not sure where to look.

I don’t think Ghostscript uses Fontconfig. When I do “apt showpkg
ghostscript” on my Debian system, there is no sign of libfontconfig1
in its dependencies, as is present for example for Inkscape.

On the other hand, when I run “gs --help”, in the usage summary it
reports “Ghostscript is also using fontconfig to search for font files”.

This page <https://ghostscript.com/doc/current/Fonts.htm> describes
how Ghostscript finds its fonts. I can find no mention of Fontconfig
there. Instead, you have to manage a “Fontmap” file.

Looking at my installed Ghostscript package under Debian, I see a
directory called “/etc/ghostscript/fontmap.d/”. I think this is where
you place Fontmap-type files.

Ah, turns out the “Fontmap” file is located in
/var/lib/ghostscript/fonts/, and Debian provides a
/usr/sbin/update-gsfontmap script to regenerate that from the contents
of the fontmap.d directory.

Is there a per-user directory as well? Don’t know ...

Not for (re)generating the Fontmap, but there is for Fontconfig.

Are you running the Fontconfig tools as the same user as Ghostscript?
Just to be sure they are looking at the same config ...
