EQN2GRAPH(1)                         General Commands Manual                         EQN2GRAPH(1)

NAME
       eqn2graph - convert an EQN equation into a cropped image

SYNOPSIS
       eqn2graph [-format output-format] [convert-arguments]

       eqn2graph --help

       eqn2graph -v
       eqn2graph --version

DESCRIPTION
       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 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.

       -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 direc-
              tory where temporary files will be created.  If none are set, /tmp is used.

AUTHORS
       eqn2graph  was  written  by  Eric  S.  Raymond  <esr AT thyrsus.com>,  based  on a recipe for
