Abstract

A system and process for ensuring the smooth flow of electronic ink is described. Dynamic rendering is give priority over other event handlers. Priority may be the use of one or more queues to order when events occur and may be performing dynamic rendering prior to other steps.

Claims

1. A renderer object for rendering ink comprising:

an interface for plugging in said object to a component that coordinates how ink is processed by objects.

2. The renderer object according to claim 1, wherein said component includes synchronous and asynchronous interfaces.

3. The renderer object according to claim 2, wherein said renderer object is connected to said synchronous interface of said component.

4. The renderer object according to claim 1, wherein said component is one of two components,

wherein said renderer object is on a synchronous interface of said first of said two components, and

said second component has at least one additional object associated with it.

5. The renderer object according to claim 1, further comprising:

a cache for temporarily storing data that has been rendered.

6. The renderer object according to claim 1, wherein said component includes input and output queues.

7. The renderer object according to claim 6, wherein said component has been additional queue associated with a synchronous interface.

8. The renderer object according to claim 1, wherein said renderer object is part of a synchronous plug-in collection.

9. The renderer object according to claim 1, wherein said renderer object is part of a synchronous plug-in chain.

10. The renderer object according to claim 1, wherein said data originated with a tablet.

11. The renderer object according to claim 1, said renderer object including an interface that allows said renderer object to be chained with other objects.

12. A method for dynamically rendering ink using a rendering object, said rendering object having an interface, said method comprising the steps of:

receiving ink from a component that orders how data is handled, said ink being received over said interface which is attached to a synchronous interface on the component; and

rendering said ink.

13. The method of according to claim 12, further comprising the steps of:

temporarily caching said rendered ink.

14. The method of according to claim 13, further comprising the steps of:

receiving a notification; and

clearing said cash of said rendered ink in response to said notification.

15. The method of according to claim 12, wherein said rendering step provides a user with the appearance of uninterrupted ink flowing from a stylus.

16. The method of according to claim 12, wherein said rendering object is part of 80 synchronous plug-in collection attached to said component.

17. The method of according to claim 12, further comprising the step of:

passing data to another object connected to said rendering object.

18. A computer-readable medium having a program stored thereon, said program for dynamically rendering ink using a rendering object, said rendering object having an interface, said program comprising the steps of:

receiving ink from a component that orders how data is handled, said ink being received over said interface which is attached to a synchronous interface on the component; and

rendering said ink.

19. The computer-readable medium of according to claim 18, said program further comprising the steps of:

temporarily caching said rendered ink.

20. The computer-readable medium of according to claim 19, said program further comprising the steps of:

receiving a notification; and

clearing said cash of said rendered ink in response to said notification.

21. The computer-readable medium of according to claim 18, wherein said rendering step provides a user with the appearance of uninterrupted ink flowing from a stylus.

22. The computer-readable medium of according to claim 18, wherein said rendering object is part of 80 synchronous plug-in collection attached to said component.

23. The computer-readable medium of according to claim 18, said program further comprising the step of:

passing data to another object connected to said rendering object.

24. A computer-readable medium having a program relating to a renderer object, said renderer object comprising:

functional code for rendering received data;

and interface for connecting said renderer object to a component that organizes the processing of said data;

wherein said renderer object is selected from two or more renderer objects and attached to said component the at a synchronous interface.

25. The computer-readable medium according to claim 24, wherein said renderer object renders ink such that said ink appears as translucent, water-based paint.

26. The computer-readable medium according to claim 24, wherein said renderer object renders ink such that said ink appears as created by a charcoal stylus.

27. The computer-readable medium according to claim 24, wherein said renderer object renders ink such that said ink appears as moving ink.

28. A method of attaching a custom renderer to a component, said component having at least two interfaces for attaching plug-in objects, said method comprising the steps of:

providing a custom renderer;

attaching said custom renderer to a synchronous interface of said component, said component ordering the processing of data related to ink.

29. The method according to claim 28, further comprising the step of:

attaching another object to said component in a collection including said custom renderer.

30. The method according to claim 28, further comprising the step of:

chaining another object to said custom renderer so that data handled by said custom renderer is next passed to said another object.
