NAME
    eqn2graph - convert an EQN equation into a cropped image

SYNOPSIS
    eqn2graph [ -unsafe ] [ -format fmt ]

DESCRIPTION
    Reads an EQN equation (one line) as input; produces an image file (by
    default in Portable Network Graphics format) suitable for the Web as
    output.

    Your input EQN code should not have the .EQ/.EN preamble that that nor-
    mally precedes it within groff(1) macros; nor do you need to have dol-
    lar-sign or other delimiters around the equation.

    The output image will be a black-on-white graphic clipped to the small-
    est possible bounding box that contains all the black pixels. By spec-
    ifying command-line options to be passed to convert(1) you can give it
    a border, set the background transparent, set the image's pixel den-
    sity, or perform other useful transformations.

    This program uses eqn(1), groff(1), and the ImageMagick convert(1) pro-
    gram. These programs must be installed on your system and accessible
    on your $PATH for eqn2graph to work.

OPTIONS
    -unsafe
    Run groff(1) in the `unsafe' mode enabling the PIC macro sh to
    execute arbitrary commands. The default is to forbid this.

    -format fmt
    Specify an output format; the default is PNG (Portable Network
    Graphics). Any format that convert(1) can emit is supported.

    Command-line switches and arguments not listed above are passed to convert(1)
    .

FILES
    /usr/share/groff/1.18.1/tmac/eqnrc
    The eqn(1) initialization file.
