GSFTOPK(1)                             General Commands Manual                            GSFTOPK(1)



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.
