Abstract
An electronic graphic system comprises an image store for storing data defining an image, a stylus and touch tablet device for generating position data representing a sequence of positions including a first position, a brush store for storing data defining a drawing implement, and processor for processing data in the image store. Data is processed by reading patches of initial image data from the store at locations related to the position represented by the position data. An image value is determined as the value of a predetermined pixel in a patch of data at a location corresponding to the first position. Patches of image data are modified with the determined image value depending on the brush data.
