ABSTRACT:
In various embodiments, methods and systems for brush composition are described. In one particular application of brush composition, opacity issues are addressed by focusing on the composition of objects having opacity effects in terms of the brushes that are used to render the objects. By focusing on the brushes that are used in the rendering process, instead of the individual objects and their particular colors, processing economies and efficiencies can be experienced. Specifically, in some instances, because of the particular way that overlapping objects interact, focusing on the brushes that are used with the individual objects and creatively attempting to combine or compose the brushes for operating on the areas of overlap, some processing steps that might otherwise have been required at the object/color level can be eliminated, thus providing a streamlined and efficient process.
