Abstract
An electronic graphic system comprises an image store for storing data defining an image, a brush store for storing data defining a drawing implement and a stylus and touch tablet for inputting position data and other data. A spatial filter is arranged to respond to the data from the stylus and touch tablet device to filter the brush data to produce brush data defining a drawing implement of a size depending on the data from the stylus and touch tablet device. The filtered brush data is used by a drawing processor to process data in the image store.
