       pic2graph - convert a PIC diagram into a cropped image

Synopsis         top

       pic2graph [-unsafe] [-format output-format] [-eqn delimiters]

Description         top

       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.

Options         top

       --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.

Environment         top

       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.

       on a recipe by W. Richard Stevens.
