Abstract

Described is electronic ink maintained as a software object, thereby associating ink functionality with electronic ink data. The ink may be separated into words or characters, with one object per word or character. By the associated functionality, applications that deal with embedded objects in general can automatically benefit from electronic ink, including having the object'"'"'s functionality render the ink data as part the application'"'"'s document. Further, because the ink data is maintained as an object, the data is automatically persisted in association with the document into which it is embedded. Ink-aware applications may call on methods of the electronic ink object to adjust formatting, search recognized ink along with text, and perform other functions. Via the electronic ink object, electronic ink substantially approaches much of the behavior normally available with text data, without requiring applications to interpret the ink data.

Claims

1. A method for providing electronic ink to an application program for display thereof, comprising:

receiving electronic ink data;

creating an electronic ink object for maintaining information that corresponds to the electronic ink data, the object having ink-related functionality associated therewith including a function that when called interprets the electronic ink data and renders an image of the ink data therefrom;

embedding the object into a document that has data therein arranged in a format used by the application program; and

providing an interface to the application program to call the function, the application program calling the function via the interface to render the image of the ink data.

2. The method of claim 1 further comprising, normalizing the received electronic ink data into the information that corresponds to the electronic ink data.

3. The method of claim 13 further comprising, maintaining normalizing information with the electronic ink object.

4. The method of claim 1 further comprising, providing the electronic ink data to a recognizer, and receiving a recognition result therefrom.

5. The method of claim 1 wherein the recognition result includes at least one text word alternate, and further comprising, maintaining the at least one text word alternate with the electronic ink object.

6. The method of claim 1 wherein the recognition result includes baseline information, and further comprising, maintaining the baseline information with the electronic ink object.

7. The method of claim 6 wherein the image is rendered based on the baseline information.

8. The method of claim 1 wherein the image is rendered at a location that is relative to text in the document.

9. The method of claim 8 wherein the electronic ink has a baseline associated therewith that is maintained in the object, and wherein the image is rendered at the location that is relative to the text in the document by aligning the image with the text via the baseline.

10. The method of claim 1 wherein the image is rendered with a size that is relative to text in the document.

11. The method of claim 10 wherein the electronic ink has a baseline and a midline associated therewith, and wherein the size is determined based on the baseline and midline.

12. The method of claim 10 wherein the electronic ink has a ceiling associated therewith, and further comprising, determining whether the electronic ink data includes an ascender that ascends above the ceiling, and if so, scaling the ascender to not ascend above the ceiling.

13. The method of claim 10 wherein the electronic ink has a floor associated therewith, and further comprising, determining whether the electronic ink data includes a descender that descends below the floor, and if so, scaling the descender to not descend below the floor.

14. The method of claim 1 wherein embedding the object comprises, pasting the object into the document.

15. The method of claim 1 further comprising, exposing an interface to the application program including a function to enable the application program to format the ink data, receiving a call to that method including formatting parameter data, and modifying the image based on the formatting parameter data.

16. The method of claim 1 further comprising, providing the electronic ink data to a recognizer, receiving a recognition result from the recognizer including a text word alternate, maintaining the text word alternate with the electronic ink object, and exposing an interface to the application program, the interface having an associated function that enables the application program to obtain information about the text word alternate.

17. A computer-readable medium having computer-executable instructions, which when executed perform steps, comprising:

receiving electronic ink data;

creating an electronic ink object for maintaining information that corresponds to the electronic ink data, the object having associated ink-related functionality including a function that when called interprets the electronic ink data to render an image of the ink data from the electronic ink data;

embedding the object into a document that contains data in a format used by an application program; and

providing an interface to the application program to call the function to render the image of the ink data.

18. In a computing environment, a system comprising:

means for providing electronic ink data;

means for creating an electronic ink object for maintaining information that corresponds to the electronic ink data, the object having associated ink-related functionality including a function that when called interprets the electronic ink data to render an image of the ink data from the electronic ink data;

means for embedding the object into an application program file; and

interface means for receiving a call from the application program to render the image of the ink data.
