NAME

6       grap2graph - convert a grap diagram into a cropped bitmap image
7

SYNOPSIS

9       grap2graph [ -unsafe ] [ -resolution M|MxN ] [ -format fmt ]
10

DESCRIPTION

12       Reads  a  grap  program as input; produces an image file (by default in
13       Portable Network Graphics format) suitable for the Web as output.   For
14       a description of the grap language, see grap(1).
15
16       Your  graph  specification  should  not be wrapped with the .G1 and .G2
17       macros that normally guard it within groff(1) macros.
18
19       The output image will be a black-on-white graphic clipped to the small‐
20       est possible bounding box that contains all the black pixels.  By spec‐
21       ifying command-line options to be passed to convert(1) you can give  it
22       a  border,  set  the background transparent, set the image's pixel den‐
23       sity, or perform other useful transformations.
24
25       This program uses grap(1), pic(1), groff(1), and the  ImageMagick  con‐
26       vert(1)  program.   These programs must be installed on your system and
27       accessible on your $PATH for grap2graph to work.

OPTIONS

30       -unsafe
31              Run pic(1) and groff(1) in the `unsafe' mode  enabling  the  PIC
32              macro  sh to execute arbitrary commands.  The default is to for‐
33              bid this.
34
35       -format fmt
36              Specify an output format; the default is PNG  (Portable  Network
37              Graphics).  Any format that convert(1) can emit is supported.
38
39       Command-line switches and arguments not listed above are passed to con‐
40       vert(1).
41

ENVIRONMENT

43       GROFF_TMPDIR
44              The directory in which temporary files will be created.  If this
45              is not set grap2graph searches the environment variables TMPDIR,
46              TMP, and TEMP (in that order).  Otherwise, temporary files  will
47              be created in /tmp.
