Method, apparatus and system for associating an intermediate fill with a plurality of objects

摘要

A method of associating a shared fill with a plurality of objects, is disclosed. Each of the objects is associated with a fill. A bounding region of the shared fill is determined based on a fill of a first of the plurality of objects. The first object is associated with the shared fill. A second object is received and the shared fill is updated based on a fill of the second object if: (a) the fill of the second object is contained within the bounding region; and (b) the fill of the second object is non-overlapping with the fill of the first object. The second object is associated with the updated intermediate fill. The updated shared fill is shared by the first object and the second object.

1. A method of rendering a plurality of objects, the method comprising:
receiving a display list representation comprising a first display list object associated with a first fill and a first path, and a second display list object associated with a second fill and a second path; determining a bounding region of a shared fill based on the first fill, wherein a size of the bounding region is affected by a complexity measure of at least one of the first object and the first fill; associating the first display list object with the shared fill by setting the first fill of the first display list object to the shared fill; updating the shared fill using the second fill in response to determining if the second fill is compatible with the first fill and the second fill is: (a) contained within the bounding region, and (b) non-overlapping with the first fill; associating the second display list object with the updated shared fill, the updated shared fill being shared, in the display list representation, by the first display list object and the second display list object; and rendering the first object and the second object using the first path and the second path associated with the updated shared fill.
