Abstract:
1. A method of improving edge rendering of objects at a common edge of two different object types in which a hint for one object disables rendering that would be pleasing at the boundary of the other object, comprising: providing a first object which has a portion of a common edge with a second object; wherein the first object has associated with it a first region of a tag plane for defining rendering hints for rendering the first object, wherein each pixel in the first object has a corresponding pixel hint in the first region of the tag plane; wherein the second object has associated with it a second region of the tag plane for defining rendering hints for rendering the second object, wherein each pixel in the second object has a corresponding pixel hint in second region of the tag plane; specifying a number of pixels located on the portion of the common edge between the first object and the second object to be modified, wherein modification may include increasing or decreasing the number of pixels on one of the first object or the second object; and modifying the first region of the tag plane corresponding to the first object by the specified number of pixels at the boundary of the first and second objects without modifying the corresponding pixels in the first object, wherein the specified number of pixel hints in the first region of the tag plane are modified without modifying the corresponding pixels in the first object.
