Efficient banded hybrid rendering
摘要:
Disclosed is a method of band rendering an image. The method comprises receiving (201) object data of the image in the page description language. From this the method determines a plurality of buckets (bucket #1-#3, FIG. 14) by which the object data is to be divided. The method then assigns (FIG. 3, 350) object data of each object in the image to one of the buckets based on an initial visibility of the object in the image. Then, for each band of the image, in a band sequential fashion (900, 920), the method identifies (1016-1024) object data visible within a band from a subset of the buckets active for the band. Then, the method analysis (FIGS. 10(i)-(iii); 1028-1052) the identified object data within the band and selects at least one rendering method (RCCR, PCR) from a plurality of rendering methods by which the band is to be rendered. Then the method renders (960,970) the identified object data into the band from the object data using the selected at least one rendering method.
