       eqn2graph - convert an EQN equation into a cropped image

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

       -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.

              Display version information and exit.

Environment         top

       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.
