GRAP2GRAPH(1)                                                                                  GRAP2GRAPH(1)

       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 for-mat) format)
       mat) 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,  tempo-rary temporary
              rary files will be created in /tmp.

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