Name
       grap2graph - convert a grap diagram into a cropped image

Synopsis
       grap2graph [-unsafe] [-format output-format] [convert-argument ...]

       grap2graph --help

       grap2graph -v
       grap2graph --version

Description
       grap2graph reads a grap(1) program from the standard input and writes an image file, by default in Portable Network Graph‐
       ics (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.

Options
       --help displays a usage message, while -v and --version show version information; all exit afterward.

       -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.
