|
|
Vg is an OCaml module for declarative 2D vector graphics. In Vg, images
|
|
are values that denote functions mapping points of the cartesian plane
|
|
to colors. The module provides combinators to define and compose these
|
|
values.
|
|
|
|
Renderers for PDF, SVG and the HTML canvas are distributed with the
|
|
module. An API allows to implement new renderers.
