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.
