EQN2GRAPH(1)                                                      EQN2GRAPH(1)

       eqn2graph - convert an EQN equation into a cropped image

       eqn2graph [ -unsafe ] [ -format fmt ]

       Reads an EQN equation (one line) as input; produces an image file (by default in Portable Network Graphics for-
       mat) 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.

              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).
