NAME
grap2graph - convert a GRAP diagram into a cropped image
SYNOPSIS
[ -unsafe ]
[ -format output-format ]
[convert-arguments]
--help
-v
--version
DESCRIPTION
grap2graph
reads a
grap(1)
program from the standard input and writes an image file,
by default in Portable Network Graphics (PNG) format,
to the standard output.
The input GRAP code should
not
be wrapped with the
.G1
and
.G2
macros that normally guard it within
groff(1)
documents.
Arguments not recognized by
grap2graph
are passed to the ImageMagick or GraphicsMagick program
convert(1).
By specifying these, you can give your image a border,
set the image's pixel density,
or perform other useful transformations.
The output image is clipped using
convert's
-trim
option to the smallest possible bounding box that contains all the black
pixels.
OPTIONS
- -format output-format
-
Write the image in
output-format,
which must be understood by
convert;
the default is PNG.
- --help
-
Display a usage message and exit.
- -unsafe
-
Run
groff
in
unsafe
mode, enabling the PIC command
sh
to execute arbitrary Unix shell commands.
The
groff
default is to forbid this.
- -v
-
--version
Display version information and exit.
ENVIRONMENT
