User Commands 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) suit-
able 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 back-
ground transparent, set the image's pixel density, or per-
form other useful transformations.
This program uses geqn(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 geqn(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). Oth-
erwise, temporary files will be created in /tmp.
