Abstract
The invention provides a method and apparatus for customizing and substituting strokes provided by a standard API. In a preferred embodiment, a stroke interface that encapsulates stroking algorithms and interfaces for stroke calculation is provided by an API. The stroke interface is provided in the form of a class. The use of the stroke interface permits additional algorithms and interfaces to be provided as new classes. This allows developers to customize stroke characteristics and attributes. In a preferred embodiment, a basic stroke class contains standard stroke characteristics of a logical pen. These characteristics include line width, end cap shape, line join style, and dash attributes.
