       pic2graph - convert a PIC diagram into a cropped image

       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

       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

       -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.

              Run groff in unsafe mode, enabling the PIC command sh  to  execute  arbitrary  Unix
              shell commands.  The groff default is to forbid this.

              Display version information and exit.


       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.
