gsftopk is a program which calls up the ghostscript program
gs(1)
to render a given font at a given resolution. It packs the resulting
characters into the
pk file format and writes them to a file whose name
is formed from the font name and the resolution (rounded to the nearest
integer). The font may be in any format acceptable to Ghostscript, including
.
pfa, .
pfb, .
gsf, and .
ttf files.
This program should normally be called by a script, such as
mktexpk, to
create fonts on demand.
gsftopk obtains the character widths from the .
tfm file, which
must exist in the standard search path. It also must be able to find the font
in a map file (such as
psfonts.map), formatted as in
dvips(1)),
unless the
--mapline option is used. The set of map files is given by
the
--mapfile option, or in the files
config.ps,
$HOME/.dvipsrc, and
config.gsftopk (as would be used by
dvips
-Pgsftopk).
The following
pk "specials" are added at the end of the output
file, to provide an internal check on the contents of the file: "
jobname= font", "
mag=1", "
mode=modeless", and "
pixels_per_inch=dpi". This is in accordance with the TeX
Directory Standard (TDS).
- --debug=n
- Set the Kpathsea debug flags according to the
integer n.
- --dosnames
- Use a name of the form font.pk instead of
font.dpipk.
- -h, --help
- Print a brief help synopsis and exit.
- -i path, --interpreter=path
- Use path as the Ghostscript interpreter.
- --mapfile=file
- Use file to look for the map information for
font. This should be the full name of the file (in other words, no
path searching algorithms are applied).
- --mapline=line
- Use line instead of looking for an entry in a map
file. The first word of line must match font.
- -q, --quiet
- Operate quietly; i.e., without writing any messages to the
standard output.
- -t, --test
- Test run: return zero status if the font can be found in
the map file(s), and nonzero status if it cannot. If this option is
specified, then the dpi argument is optional (since the font will
not be generated).
- -v, --version
- Print the version number and exit.
- DVIPSRC
- Name of file to read instead of $HOME/.dvipsrc. This
should be the full name of the file (in other words, no path searching
algorithms are applied).

- GSFTOPKHEADERS
- See TEXPSHEADERS.
- PSHEADERS
- See TEXPSHEADERS.
- TEXCONFIG
- Colon-separated list of paths to search for map files. An
extra colon in the list will include the compiled-in default paths at that
point. A double slash will enable recursive subdirectory searching at that
point in the path.
- TFMFONTS
- Colon-separated list of paths to search for the .tfm
file associated with the font. Double slashes and extra colons behave as
with TEXCONFIG. This information may also be
supplied by using the environment variables TFMFONTS
or GSFTOPKFONTS. These environment variables are
checked in the order GSFTOPKFONTS,
TFMFONTS, TFMFONTS; the first
one (if any) having a value is used.
- TEXPSHEADERS
- Colon-separated list of paths to search for the Ghostscript
driver file render.ps and for any PostScript header or font files
(.enc, .pfa, .pfb, .gsf, or .ttf
files). Double slashes and extra colons behave as with
TEXCONFIG. This information may also be supplied by
using the environment variables PSHEADERS or
GSFTOPKHEADERS. These environment variables are
checked in the order GSFTOPKHEADERS,
TEXPSHEADERS, PSHEADERS; the
first one (if any) having a value is used.
- TFMFONTS
- See TFMFONTS.
In order to determine the set of map files to be used and the path for finding
PostScript files,
gsftopk reads, in order, the files
config.ps,
.dvipsrc, and
config.gsftopk. The files
config.ps and
config.gsftopk are searched for using the environment variable
TEXCONFIG, the
Kpathsea configuration file, or
the compiled-in default paths. The file
.dvipsrc is searched for in the
user's home directory.
These files are in the same format as for
dvips (as well as being in the
same locations). The entries used by
gsftopk are as follows.
- H path
- Indicates that the Ghostscript driver file render.ps
and the PostScript header and font files are to be searched for using
path.
- p file
- Indicates that the list of map files is to be erased and
replaced by file.
- p +file
- Indicates that file is to be added to the list of
map files.
All other entries are ignored.
This is similar to the handling of these options when running
dvips
-Pgsftopk. For more details, see the
Kpathsea manual.
gsftopk sometimes has trouble with fonts with very complicated characters
(such as the Seal of the University of California). This is because
gsftopk uses the
charpath operator to determine the bounding box
of each character. If the character is too complicated, then old versions of
Ghostscript fail, causing
gsftopk to terminate with an error message
- Call to gs stopped by signal 10
(The number may vary from system to system; it corresponds to a bus error or a
segmentation fault.) The best way to fix this bug is to install a current
version of ghostscript. As an alternative,
gsftopk can be instructed to
use the bounding box provided with the font (if one exists) instead of finding
a bounding box for each character. To do this, include the string
- /usefontbbox true def
in the font map file;
e.g.,
- ucseal "/usefontbbox true def"
This will not affect use of the font by
dvips.
