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, in-
       cluding .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 ex-
       ist 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  con-
       fig.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 en-
                       able 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  ex-
                       tra  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,  TFM-
                       FONTS; 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 re-
              placed 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  be-
       cause  gsftopk uses the charpath operator to determine the bounding box
       of each character.  If the character is too complicated, then old  ver-
       sions  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 er-
       ror  or  a segmentation fault.)  The best way to fix this bug is to in-
       stall 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.
