Описание (Description)
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.
Параметры (Options)
--help
displays a usage message, while -v
and --version
show
version information; all exit afterward.
-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.
-unsafe
Run groff in unsafe mode, enabling the PIC command sh
to
execute arbitrary Unix shell commands. The groff default
is to forbid this.
Окружение (Environment)
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.
