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.

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

          /usefontbbox true def

   in the font map file; e.g.,

          ucseal "/usefontbbox true def"

   This will not affect use of the font by dvips.
