A system and method providing a cursor tool framework and tool server with support for multiple cursors on any given system, and supporting the selection of a cursor tool using a cursor. The framework and server facilitate the association of cursor tools to a cursor in a process-independent space such that tools can be used cross-process and cross-document. The framework also provides default functionality for communication among cursor tools and the canvas on which they are used. This high degree of interaction allows any cursor tool and any document to function together such that the cursor tool can be written without the participation of the document developer.

Computer software, process, and object-oriented objects that decouple the details of accessing graphical data from the details of processing and iterating through the graphical data. The invention first receives a filter routine and a funnel routine, and passes an iterator, that enumerates over the graphical data, to the funnel routine. Then the invention repetitively calls both the filter and funnel routines to enumerate over the graphical data. The filter routine selects, orders and returns graphical data. The funnel routine processes the graphical data and also can pre-terminate enumeration. Developers have the capability extend the invention by providing their own versions of the filter and funnel routines and by modifying the enumeration.

Image rendering system with extensible mechanism for providing visual

A computer based system for rendering a plurality of graphical environments includes a plurality of painter maker objects, and a painter maker chain comprising at least one of the painter maker objects. A task, which is coupled to the painter maker chain, passes to the painter maker chain a request to render a particular graphical primitive in a particular graphical environment. In response to the request, the painter maker objects create a painter chain comprising a plurality of painter objects each optimized to perform, in the particular graphical environment, a predetermined graphical operation in order to render the particular graphical primitive. The task uses painter objects to perform rendering operations in the particular graphical environment.
