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

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
