       eqn2graph - convert an eqn equation into a cropped image

Synopsis         top

Description         top

       eqn2graph reads a one-line eqn(1) equation from the standard
       input and writes an image file, by default in Portable Network
       Graphics (PNG) format, to the standard output.

       The input EQN code should not be preceded by the .EQ macro that
       normally precedes it within groff(1) macros; nor do you need to
       have dollar-sign or other delimiters around the equation.

       Arguments not recognized by eqn2graph 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         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.

Environment         top

       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.

Authors         top

       eqn2graph was written by Eric S. Raymond ⟨esr@thyrsus.com⟩, based
       on a recipe for pic2graph(1), by W. Richard Stevens.
