EQN2GRAPH(1)						      General Commands Manual						      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/1.18.1/tmac/eqnrc  The eqn(1) initialization file.

SEE ALSO

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

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.
