EQN2GRAPH(1)                General Commands Manual               EQN2GRAPH(1)



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
       normally precedes it within groff(1) macros; nor do you need to have
       dollar-sign or other delimiters around the equation.

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

       This program uses eqn(1), groff(1), and the ImageMagick convert(1)
       program.  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/1.18.1.1/tmac/eqnrc
              The eqn(1) initialization file.
