GRAP2GRAPH(1)              General Commands Manual             GRAP2GRAPH(1)

NAME         top

       grap2graph - convert a grap diagram into a cropped bitmap image

SYNOPSIS         top

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

DESCRIPTION         top

       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         top

       -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         top

       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.
