       grap2graph - convert a GRAP diagram into a cropped image


       grap2graph [-unsafe] [-format output-format] [convert-arguments]

       grap2graph --help

       grap2graph -v
       grap2graph --version


       grap2graph  reads  a  grap(1) program from the standard input and writes an image file, by
       default in Portable Network Graphics (PNG) format, to the standard output.

       The input GRAP code should not be wrapped with the .G1 and .G2 macros that normally  guard
       it within groff(1) documents.

       Arguments  not  recognized  by  grap2graph 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.


       -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.


       grap2graph  was  written  by  Eric  S.  Raymond  ⟨⟩,  based on a recipe for
       pic2graph(1), by W. Richard Stevens.
