NAME
eqn2graph - convert an EQN equation into a cropped image
SYNOPSIS
[ -format output-format ]
[convert-arguments]
--help
-v
--version
DESCRIPTION
eqn2graph
reads a one-line
eqn(1)
equation from the standard input and writes an image file,
by default in Portable Network Graphics (PNG) format,
to the standard output.
The input EQN code should
not
be preceded by the
.EQ
macro that normally precedes it within
groff(1)
macros;
nor do you need to have dollar-sign or other delimiters around the
equation.
Arguments not recognized by
eqn2graph
are passed to the ImageMagick or GraphicsMagick program
convert(1).
By specifying these, you can give your image a border,
set the image's pixel density,
or perform other useful transformations.
The output image is clipped using
convert's
-trim
option to the smallest possible bounding box that contains all the black
pixels.
OPTIONS
- -format output-format
-
Write the image in
output-format,
which must be understood by
convert;
the default is PNG.
- --help
-
Display a usage message and exit.
- -v
