       grap2graph - convert a grap diagram into a cropped image

Synopsis         top

                  argument ...]

Description         top

       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

Options         top

       --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.

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

Environment         top

       TEMP   These environment variables are searched in the order
              shown to determine the directory where temporary files
              will be created.  If none are set, /tmp is used.

Authors         top

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