Expand description
A 2D graphics abstraction.
This crate contains types and interfaces that represent a traditional 2D
graphics API, in the tradition of PostScript. It is built on top of
kurbo, a 2D geometry library.
The main interface is the RenderContext trait.
This API can be implemented on various platforms, allowing drawing code
to be reused in an approximately consistent way. Various such implementations
exist, such as piet-cairo, piet-coregraphics, and piet-direct2d.
If you are interested in using piet to target multiple platforms,
piet-common is a utility crate that re-exports an appropriate
backend based on the compile target, and provides convenience
types and methods for setting up a RenderContext.
