    Command:

    eqn2graph

    
    
    

    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/share/groff/1.18.1.4/tmac/eqnrc
                  The eqn(1) initialization file.
