NAME
       gsftopk - render a ghostscript font in TeX pk form

SYNOPSIS
       gsftopk   [-i   path]  [-q]  [-t]  [--debug=n]  [--dosnames]  [--inter-
       preter=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 accor-
       dance 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 stan-
              dard 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 informa-
                       tion may also be  supplied  by  using  the  environment
                       variables  TFMFONTS or GSFTOPKFONTS.  These environment
                       variables are checked in the order  GSFTOPKFONTS,  TFM-
                       FONTS,  TFMFONTS; the first one (if any) having a value
                       is used.

       TEXPSHEADERS    Colon-separated list of paths to search for the  Ghost-
                       script  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 GSFTOP-
                       KHEADERS.  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  .dvip-
       src 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  charac-
       ters  (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.
