Abstract

The present invention relates to interfacing with electronic ink. Ink is stored in a data structure that permits later retrieval by applications. The ink includes stroke information and may include property information. Through various programming interfaces, one may interact with the ink through methods and setting or retrieving properties. Other objects and collections may be used as well in conjunction with the ink objects.

Claims

1. A method of communicating between an application and an ink object, said ink object storing electronic ink, comprising the steps of:

receiving, from said application, a request to said ink object for a nearest point to a submitted point;

processing said request by said ink object; and

returning, by said ink object, information in response to said request, the information including an identity of a stroke containing the nearest point.

2. The method according to claim 1, further including:

receiving, from said application, a clone request to said ink object;

processing, by said ink object, said clone request; and

returning, by said ink object, information in response to said clone request.

3. The method according to claim 1, further including:

receiving, from said application, a hit test request to said ink object;

processing, by said ink object, said hit test request; and

returning, by said ink object, information in response to said clone request.

4. The method according to claim 1, further including:

receiving, from said application, a request to obtain a bounding box;

processing, by said ink object, said request to obtain the bounding box; and

returning, by said ink object, information in response to said request to obtain a bounding box.

5. The method according to claim 1, further including:

receiving, from said application, a request to extract strokes of said electronic ink for placement into another ink object;

processing, by said ink object, said request to extract strokes; and

returning, by said ink object, information in response to said request to extract strokes.

6. The method according to claim 1, further including:

receiving, from said application, a request to determine whether said ink object can paste ink information to a clipboard;

processing, by said ink object, said request to determine; and

returning, by said ink object, information in response to said request to determine.

7. The method of claim 1 wherein the ink object exists prior to the issuing step.

8. The method of claim 1, wherein the information further includes a distance between the submitted point and the nearest point.

9. A method of communicating between an application and an ink object, said ink object storing electronic ink, comprising the steps of:

issuing, by said application, a request for a nearest point to a submitted point;

receiving, from said ink object, information in response to said request, the information including an identity of a stroke containing the nearest point.

10. The method of claim 9, wherein the information further includes a distance between the submitted point and the nearest point.
