摘要：
A method generates a two-dimensional distance field from a pen stroke. A pen state is sampled during the pen stroke to generate an ordered list of pen states along the pen stroke. The pen state includes a location of the pen stroke. A set of boundary descriptors is generated from the ordered list of pen states. The two-dimensional distance field is generated from the set of boundary descriptors.
