摘要： A Hybrid Compressor (304) and method (500) of compressing a tile (2200) of pixels within an image are disclosed. An Edge Processor (404) of the Hybrid Compressor (304) analyses pixel runs (403) of the tile (2200) and generates boundary data defining one or more regions comprising pixels of substantially identical colour. A Palette Processor (411) of the Hybrid Compressor (304) generates data defining a colour value for each region. An Image Processor (416) of the Hybrid Compressor (304) generates a representation of pixels not included in the one or more regions.

摘要： A method of storing an image is disclosed. A frequency-domain representation of the image is received, the frequency-domain representation having a plurality of bit-planes. The frequency-domain representation is divided into a first set of bit-planes and a second set of bit-planes, the first set of bit-planes being a higher set of bit-planes than the second set of bit-planes. The first set of bit-planes and the second set of bit-planes is partitioned into a plurality of partitions. At least one partition from the second set of bit-planes is inserted into the plurality of partitions of the first set of bit-planes to produce a plurality of arranged partitions of the image. The arranged partitions of the image are stored.

摘要： A method of processing received objects in a rendering system determines whether a detection scheme which already has grouped objects exits. The rendering system has a plurality of detection schemes, with each detection schemes having an associated object group type. If such a detection scheme does not exist and a previously received object has been stored, then the method determines in descending priority order whether one of the detection schemes is operative to group the received object with the previously received object. If it is determined that none of the detection schemes is operative to group the received object with the previously received object, then the previously received object is output for rendering the received object is stored. If it is determined that one of the detection schemes is operative to group the received object with the previously received object, then the received object is grouped with the previously received object.
