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 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.
