Abstract

Ink is stored in a data structure that permits later retrieval by applications. The ink includes stroke information and property information. Properties may be associated globally with the ink strokes and/or with each stroke individually. Aspects include a data structure that supports ink for multiple applications. Using the storage system, method, and data structure, various applications may expand on ink to include additional attributes while permitting the ink to be used in applications not supporting the additional attributes. When encountering an unknown tag, the applications will skip past the end of the tag and its associated data to start reading the next tag.

Claims

1. A computer readable medium having a data structure thereon for storing an ink object, said data structure comprising:

a first portion having an ink object identifier;

a second portion identifying a size or count of tag data;

and a third portion having the tag data.

2. The computer readable medium according to claim 1, wherein said data structure further comprises a fourth portion relating to a version of the ink object.

3. The computer readable medium according to claim 1, wherein said data structure further comprises a fourth portion describing global properties.

4. The computer readable medium according to claim 1, wherein said data structure further comprises a fourth portion describing a global unique identifier.

5. The computer readable medium according to claim 1, wherein said data structure further comprises a fourth portion describing an ink space rectangle.

6. The computer readable medium according to claim 1, wherein said data structure further comprises a fourth portion describing drawing attributes.

7. The computer readable medium according to claim 1, wherein said data structure further comprises a fourth portion describing stroke descriptors.

8. The computer readable medium according to claim 1, wherein said data structure further comprises a fourth portion describing metrics.

9. The computer readable medium according to claim 1, wherein said data structure further comprises a fourth portion describing the compression used.

10. The computer readable medium according to claim 1, wherein said data structure further comprises a fourth portion describing local properties.

11. The computer readable medium according to claim 1, wherein said data structure further comprises a fourth portion describing a drawing attribute index.

12. The computer readable medium according to claim 1, wherein said data structure is encoded.

13. The computer readable medium according to claim 1, wherein said data structure further comprises a fourth portion describing predefined and custom GUIDs.
