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.
arguments
font
Name of the font to be created.
dpi
Desired resolution of the font to be created, in dots per inch.
This may be a real number.
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.
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).

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.
