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.
