GRAP2GRAPH(1)                          General Commands Manual                         GRAP2GRAPH(1)



NAME
       grap2graph - convert a GRAP diagram into a cropped image

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

       grap2graph --help

       grap2graph -v
       grap2graph --version

DESCRIPTION
       grap2graph  reads  a grap(1) program from the standard input and writes an image file, by de‐
       fault 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 pro‐
       gram 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
       -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.
