grap2graph(1) General Commands Manual grap2graph(1)
Name
grap2graph - convert a grap diagram into a cropped image
Synopsis
grap2graph [-unsafe] [-format output-format] [convert-
argument ...]
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
smallest possible bounding box that contains all the black
pixels.
Options
--help displays a usage message, while -v and --version show
version information; all exit afterward.
-format output-format
Write the image in output-format, which must be understood
by convert; the default is PNG.
-unsafe
Run groff in unsafe mode, enabling the PIC command sh to
execute arbitrary Unix shell commands. The groff default
is to forbid this.
Environment
GROFF_TMPDIR
TMPDIR
TMP
TEMP These environment variables are searched in the order
shown to determine the directory where temporary files
will be created. If none are set, /tmp is used.
Authors
grap2graph was written by Eric S. Raymond ⟨esr@thyrsus.com⟩,
based on a recipe for pic2graph(1), by W. Richard Stevens.
