The memory includes means for spacing ink stroke representations, means for recognizing outline elements, means for performing deferred recognition, means for highlighting drawing areas and means for storing and displaying ink stroke representations. These means operate together to provide a pen-based or graphics oriented computer system with improved performance and added functionality for manipulating the space between ink stroke representations. The preferred embodiment of the present invention comprises several novel methods that provide this functionality including: a method for managing space between ink stroke representations, a method for displaying drawing elements in a visually distinct manner, a method for recognizing bullets and dashes, a method for storing ink stroke representations, a method for displaying and printing ink stroke representations, and a method for performing deferred character or word recognition.Field of SearchEDITING, ERROR CHECKING, OR CORRECTION (E.G., POSTRECOGNITION PROCESSING)Including operator interaction Separating document regions using preprinted guides or markings Segmenting individual characters or words Segmenting hand-printed characters On-line recognition of handwritten characters IMAGE TRANSFORMATION OR PREPROCESSING Where the object is a character, word, or text Changing the image coordinates Stylus | |
