[--help] [--version] font dpi
ARGUMENTS

DESCRIPTION
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).
OPTIONS
- --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.
ENVIRONMENT VARIABLES
- 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).
- GSFTOPKFONTS
- See TFMFONTS.
- 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.
CONFIGURATION
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.
BUGS
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.
