GRAP2GRAPH(1)		    General Commands 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	small-
       est possible bounding box that contains all the black pixels.  By spec-
       ifying command-line options to be passed	to convert(1) you can give  it
       a  border,  set	the background transparent, set	the image's pixel den-
       sity, or	perform	other useful transformations.

       This program uses grap(1), pic(1), groff(1), and	the  ImageMagick  con-
       vert(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 for-
	      bid 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 con-
       vert(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.
