pic2graph(1) General Commands Manual pic2graph(1)
pic2graph - convert a PIC diagram into a cropped image
pic2graph [-unsafe] [-format output-format] [-eqn delimiters]
[convert-arguments]
pic2graph --help
pic2graph -v
pic2graph --version
pic2graph reads a pic(1) program from the standard input and writes
an image file, by default in Portable Network Graphics (PNG) format,
to the standard output. It furthermore translates eqn(1) constructs,
so it can be used for generating images of mathematical formulae.
The input PIC code should not be wrapped with the .PS and .PE macros
that normally guard it within groff(1) documents.
Arguments not recognized by pic2graph 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.
-eqn delimiters
Use delimiters as the opening and closing characters that
delimit eqn directives; the default is “$$”. The option
argument delimiters should be a two-character string, but an
empty string ("") is accepted as a directive to disable eqn
processing.
-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.
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.
