grap2graph(1) General Commands Manual grap2graph(1)
grap2graph - convert a GRAP diagram into a cropped image
grap2graph [-unsafe] [-format output-format] [convert-arguments]
grap2graph --help
grap2graph -v
grap2graph --version
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.
-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.

TEMP These environment variables are searched in the given order to
determine the directory where temporary files will be created.
If none are set, /tmp is used.
grap2graph was written by Eric S. Raymond ⟨esr@thyrsus.com⟩, based on
a recipe for pic2graph(1), by W. Richard Stevens.
