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 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 documents.
Arguments not recognized by grap2graph are passed to the
ImageMagick or GraphicsMagick program 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.
--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.
GROFF_TMPDIR
TMPDIR
TMP
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.
