PIC2GRAPH(1)                           General Commands Manual                          PIC2GRAPH(1)



NAME
       pic2graph - convert a PIC diagram into a cropped image

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

       pic2graph --help

       pic2graph -v
       pic2graph --version

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.

OPTIONS
       -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
       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.
