Abstract
The present invention relates to obtaining vector data for a hand-drawn curve having coordinate values input from a pointing device and a thickness and/or density in accordance with pen pressure values. In order to reduce the amount of data input from the pointing device and obtain vector data therefor in real time, the coordinate data and pen pressure data are extracted independently of each other so as to reduce the amount of data stored in a memory and used for plotting or display.
