eqn2graph - convert an EQN equation into a cropped image
eqn2graph [-format output-format] [convert-arguments]
eqn2graph --help
eqn2graph -v
eqn2graph --version
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.
-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
--version
Display version information and exit.
