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  de‐
       mand.

       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), for‐
       matted 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 "pix‐
       els_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 infor‐
                       mation may also be supplied by using the environment  variables  TFMFONTS  or
                       GSFTOPKFONTS.   These environment variables are checked in the order GSFTOPK‐
                       FONTS, 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  ren‐
                       der.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  de‐
       tails, 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  de‐
       termine  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.
