Имя (Name)
eqn2graph - convert an eqn equation into a cropped image
Синопсис (Synopsis)
eqn2graph [-format output-format] [convert-arguments]
eqn2graph --help
eqn2graph -v
eqn2graph --version
Описание (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.
Параметры (Options)
--help displays a usage message, while -v and --version show
version information; all exit afterward.
-format output-format
Write the image in output-format, which must be understood
by convert; the default is PNG.
