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 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 con-
       vert(1).

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

SEE ALSO
       eqn(1), groff(1), gs(1),	convert(1).
