PIC2GRAPH(1)               General Commands Manual              PIC2GRAPH(1)

NAME         top

       pic2graph - convert a PIC diagram into a cropped image

SYNOPSIS         top

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

       pic2graph --help

       pic2graph -v
       pic2graph --version

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

       -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.

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.
