       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 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

       The output image will be a black-on-white graphic clipped to the smallest possible  bound-
       ing  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 pro-
       grams 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 for-
	      mat that convert(1) can emit is supported.

       Command-line switches and arguments not listed above are passed to convert(1).

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

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