       grap2graph - convert a grap diagram into a cropped bitmap image


       grap2graph [ -unsafe ] [ -resolution M|MxN ] [ -format fmt ]


       Reads  a  grap  program  as  input; produces an image file (by default in Portable Network
       Graphics format) suitable for the Web as output.  For a description of the grap  language,
       see grap(1).

       Your  graph  specification should not be wrapped with the .G1 and .G2 macros that normally
       guard it within groff(1) macros.

       The output image will be  a  black-on-white  graphic  clipped  to  the  smallest  possible
       bounding box that contains all the black pixels.  By specifying command-line options to be
       passed to convert(1) you can give it a border, set the  background  transparent,  set  the
       image's pixel density, or perform other useful transformations.

       This  program  uses  grap(1),  pic(1),  groff(1),  and the ImageMagick convert(1) program.
       These programs must be  installed  on  your  system  and  accessible  on  your  $PATH  for
       grap2graph to work.


              Run  pic(1)  and groff(1) in the `unsafe' mode enabling the PIC macro sh to execute
              arbitrary commands.  The default is to forbid this.

       -format fmt
              Specify an output format; the default is  PNG  (Portable  Network  Graphics).   Any
              format that convert(1) can emit is supported.

       Command-line switches and arguments not listed above are passed to convert(1).


              The  directory  in  which  temporary  files  will  be  created.  If this is not set
              grap2graph searches the environment  variables  TMPDIR,  TMP,  and  TEMP  (in  that
              order).  Otherwise, temporary files will be created in /tmp.


       pic2graph(1), eqn2graph(1), pic(1), groff(1), gs(1), convert(1).
