Abstract
The invention provides a vector graphics system. In one embodiment, the vector graphics system comprises a path rendering manager module and a rendering module. The path rendering manager module receives path data, calculates a changing rate of the path data, and selects a filling method from a tessellation filling method and a Stencil filling method according to the changing rate. The rendering module fills the path data according to the tessellation filling method when the filling method is the tessellation filling method, and fills the path data according to the Stencil filling method when the filling method is the Stencil filling method.
