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 accessi-
       ble 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.

SEE ALSO
