A method and system for altering an attribute of a graphic object in a computer system is provided. An attribute, such as a line style or fill pattern, has a plurality of formats. The computer system includes a handwriting instrument and an electronic tablet. Each attribute of a graphic object has an associated input area on the electronic tablet. The user draws a gesture with the handwriting instrument over a selected one of the input areas. The gesture drawn is indicative of a desired format selected for the attribute and associated with the selected input area. The system recognizes the gesture drawn over the selected input area and then determines the desired format represented by the gesture drawn. The system then changes the format of the attribute associated with the selected input area to the desired format. If the system is not able to recognize the gesture drawn, the user can define the gesture as a custom attribute which will be recognized by the system the next time the gesture is drawn.

Method and system of altering an attribute of a graphic object in a pen

A method and system for recognizing a graphic object's shape, line style, and fill pattern in a pen environment are provided. In a preferred embodiment, a user draws a graphic object on an electronic tablet of a computer system. The graphic object comprises a shape attribute, a line style attribute, and a fill pattern attribute. A Recognizer, recognizes the graphic object. The graphic object is made up of a plurality of data points, each data point having an x-coordinate and a y-coordinate. The Recognizer subdivides the plurality of data points into one or more strokes, each stroke representative of a path travelled by the handwriting instrument after the handwriting instrument touches the tablet and before the handwriting instrument is lifted off of the tablet. For each data point in each stroke, the recognizer maps the data point to a normalized data point, then transforms the normalized data point into a transformed data point, and then determines whether the transformed data point is a shape-defining data point or an interior-defining data point. Shape-defining data points are representative of the shape attribute and the line style attribute, while the interior-defining data points are representative of the fill pattern attribute. Based on the coordinates of the transformed data points and the coordinates of the data points, the recognizer determines the attributes. After determining the attributes of the graphic object, the recognizer selects a representation of the graphic object that corresponds to the determined attributes and displays the representation on the electronic tablet.

A method and system for recognizing a graphic object's shape, line style, and fill pattern in a pen environment are provided. In a preferred embodiment, a user draws a graphic object on an electronic tablet of a computer system. The graphic object comprises a shape attribute, a line style attribute, and a fill pattern attribute. A Recognizer, provided by the present invention, recognizes the graphic object drawn by the user. The graphic object drawn by the user is made up of a plurality of data points, each data point having an x-coordinate and a y-coordinate. The Recognizer subdivides the plurality of data points into one or more strokes, each stroke representative of a path travelled by the handwriting instrument after the handwriting instrument touches the electronic tablet and before the handwriting instrument is lifted off of the electronic tablet. For each data point in each stroke, the recognizer maps the data point to a normalized data point, then transforms the normalized data point into a transformed data point, and then determines whether the transformed data point is a shape-defining data point or an interior-defining data point. Shape-defining data points are representative of the shape attribute and the line style attribute, while the interior-defining data points are representative of the fill pattern attribute. Based on the coordinates of the transformed data points and the coordinates of the data points input by the user, the recognizer determines the attributes. After determining what the attributes of the graphic object are, the recognizer selects a representation of the graphic object that corresponds to the determined attributes and displays the selected representation on the electronic tablet.
