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
