1. In a system that captures handwriting on a digitizer tablet, a method performed by a processor for generating and storing data representing the handwriting comprising:

  • said processor processing the captured handwriting to identify strokes of the handwriting;

    said processor partitioning each stroke into a plurality of segments;

    said processor generating a plurality of parameters for each segment;

    said processor generating a compressed representation for each given segment by transforming the parameters for the given segment;

    said processor generating data representing the handwriting based upon the compressed representation for each given segment; and

    said processor storing the data representing the handwriting.
