A method of rendering a graphical object (e.g.,) on a page (), is disclosed. A region of the page containing the graphical object () is marked as output incompatible based on the graphical object () being output incompatible. A bounding box comprising the marked region is determined. A proportion of a number of the regions marked as output incompatible are determined to a total number of regions in the bounding box. A further region within the bounding box is marked as output incompatible to increase the determined proportion above a threshold. The graphical object in the marked region and the further marked region is converted into an output compatible graphical object if the determined proportion is above the threshold. The output compatible graphical object is rendered.

Method, apparatus and system for rendering an object on a page

Disclosed is a method of band rendering an image. The method comprises receiving () object data of the image in the page description language. From this the method determines a plurality of buckets (bucket #-#, FIG.) by which the object data is to be divided. The method then assigns (FIG.) 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 (), the method identifies (-) object data visible within a band from a subset of the buckets active for the band. Then, the method analysis (FIGS.()-();-) 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 () the identified object data into the band from the object data using the selected at least one rendering method.
