ABSTRACT:
Methods and apparatus, including computer program products, implementing and using techniques for performing computer graphics operations on an image represented by digital data. A representation of a digital image is received. The image includes vector objects, each specified by control points. An editing brush is provided for interactive editing of the image by a user. The editing brush has a region of influence and applies a displacement function to control points in the region of influence, whereby when the editing brush is applied by the user to the image, a local distortion of the image is generated.
