       gsftopk - render a ghostscript font in TeX pk format

       gsftopk [-i path] [-q] [-t] [--debug=n] [--dosnames] [--interpreter=path] [--mapline=line]
       [--mapfile=file] [--quiet] [--test] [--help] [--version] font dpi

       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

       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, includ-
       ing .pfa, .pfb, .gsf, and .ttf files.

       This  program  should  normally be called by a script, such as mktexpk, to create fonts on

       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 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  inter-
       nal 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).

	      Set the Kpathsea debug flags according to the integer n.

	      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.

	      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).

	      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.

       TFMFONTS      Colon-separated list of paths to search for the .tfm  file  associated  with
		     the  font.   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.

       DVIPSHEADERS  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 TFMFONTS.

       TEXCONFIG     Colon-separated  list  of paths to search for map files.  Double slashes and
		     extra colons behave as with TFMFONTS.

       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).

       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 TEXCON-
       FIG, 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.

       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 segmenta-
       tion 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.
