EQN2GRAPH(1)                                                                                    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  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.

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 convert(1).

FILES
       /usr/share/groff/1.19.2/tmac/eqnrc  The eqn(1) initialization file.

ENVIRONMENT
       GROFF_TMPDIR
              The directory in which temporary files will be created.  If this is not set eqn2graph searches
              the environment variables TMPDIR, TMP, and TEMP (in that order).  Otherwise,  temporary  files
              will be created in /tmp.
