  • Apparatus and method for defining the form and attributes of an object in an image
    Patent number: 5611036
    Abstract: Apparatus and method for defining the form and attributes of an object in an image. The form and attributes of the object are defined in such a way that the attribute data can be modified without changing the form. Attribute data may include opacity, color, and object width. In detail, a path which represents the underlying skeletal form of an object in an image is generated from path control data, which may comprise data defining path control points. Values of an attribute of the object are specified at attribute points which have a position relative to the path. The attribute points may be varied without changing the form. The apparatus and method may be used for computer painting and to generate a matte or transparency image.
