PROGRAM:

NAME

gsftopk - render a ghostscript font in TeX pk form

SYNOPSIS

gsftopk [-i path] [-q] [-t] [--debug=n] [--dosnames] [--interpreter=path] [--mapline=line]
[--mapfile=file] [--quiet] [--test] [--help] [--version] font dpi

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.

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.
