- Desired resolution

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.
- TFMFONTS
- Colon-separated list of paths to search for the .tfm
file associated with the font. 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.
- DVIPSHEADERS
- 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 TFMFONTS.
- TEXCONFIG
- Colon-separated list of paths to search for map files. Double
slashes and extra colons behave as with TFMFONTS.
- 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).
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.
