GRAP2GRAPH(1) General Commands Manual GRAP2GRAPH(1)
NAME
grap2graph - convert a GRAP diagram into a cropped image
SYNOPSIS
grap2graph [-unsafe] [-format output-format] [convert-arguments]
grap2graph --help
grap2graph -v
grap2graph --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 small-
est 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
