GRAP2GRAPH(1)              OpenBSD Reference Manual              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).
