Serial storage of ink and its properties
First Claim
1. A method for using a data structure for storing ink, said data structure being read and processed by a computer, said data structure relating to storing at least a first ink stroke and a second ink stroke of handwritten ink information, comprising the steps of:
- identifying a tag in the data structure, said tag delimiting data associated with the tag and including a reference to index data associated with a first property of the first ink stroke and a second property of the second ink stroke of the handwritten ink information;
retrieving a size of the data associated with the tag; and
if an application recognizes the tag, then reading the data associated with the tag, otherwise skipping the tag by skipping past the data based on the size of the data,wherein the first property of the handwritten ink information associated with the index data is applied to the tag data and the first ink stroke based on the reference and the second property of the handwritten ink information associated with the index data is applied to the tag data and the second ink stroke based on the reference, and wherein the properties include at least one of a specific color, line width, drawing attribute, count of points, stroke size, a shape of pen tip, a type of pen tip, a point at which a stylus starts a stroke, stroke coordinates, pressure, angle of pen, and interval of time between coordinates.

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.
