GRAP2GRAPH(1)                                                                                                      GRAP2GRAPH(1)



NAME
       grap2graph - convert a grap diagram into a cropped bitmap image

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

DESCRIPTION
       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.

OPTIONS
       -unsafe
              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).

ENVIRONMENT
       GROFF_TMPDIR
              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.

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