EQN2GRAPH(1) EQN2GRAPH(1)

NAME
       eqn2graph - convert an EQN equation into a cropped image

SYNOPSIS
       eeqqnn22ggrraapphh [ -uunnssaaffee ] [ -ffoorrmmaatt 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 ggrrooffff(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 ccoonnvveerrtt(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 eeqqnn(1), ggrrooffff(1), and the ImageMagick ccoonnvveerrtt(1) pro-
       gram.  These programs must be installed on your system  and  accessible
       on your $PATH for eeqqnn22ggrraapphh to work.

OOPPTTIIOONNSS
       -uunnssaaffee
              Run  ggrrooffff(1)  in the `unsafe' mode enabling the PIC macro sshh to
              execute arbitrary commands.  The default is to forbid this.

       -ffoorrmmaatt fmt
              Specify an output format; the default is PNG  (Portable  Network
              Graphics).  Any format that ccoonnvveerrtt(1) can emit is supported.

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

FILES       //uussrr//sshhaarree//ggrrooffff//11..1199..11//ttmmaacc//eeqqnnrrcc
              The eeqqnn(1) initialization file.

ENVIRONMENT       GGRROOFFFFTTMMPPDDIIRR
              The directory in which temporary files will be created.  If this
              is  not set eeqqnn22ggrraapphh searches the environment variables TTMMPPDDIIRR,
              TTMMPP, and TTEEMMPP (in that order).  Otherwise, temporary files  will
              be created in //ttmmpp.
