Abstract

A note taking system that integrates word-processing functionality and computerized drawing functionality for processing ink strokes comprises novel methods that provide this functionality such as: a method for modeless operation of the note taking system that automatically switches between providing word-processing functionality and drawing functionality; a novel method for processing ink strokes as drawings, a unique method for processing ink strokes as writing, and other methods for parsing the ink strokes into words, lines, and paragraphs. The present invention also includes additional methods for manipulating figures such as a division between line and shape type figures, and a special handle performing either rotation or re-sizing.
