Abstract: An object optimized printing system and method comprises a page description language decomposing system, a command instruction and data generating system and an image output terminal controller. The PDL decomposition system inputs a print file defining a plurality of pages in the page description language and locates the plurality of objects forming each page and their object types. Based on the determine object types and any explicit rendering commands in the PDL file, the PDL decomposition system automatically generates rendering tags for each of the objects. The rendering tags are used to control the command instruction and data generating system, the IOT controller and/or the image output terminal to optimize the printing by the IOT on an object-by-object basis. Based on the objects and the generated rendering tags, the command instruction and data generating system generates the differing types of data and the command instructions on a scanline-by-scanline basis.

Abstract: An imaging system for effecting electrostatic printing of an image, wherein the imaging system includes at least one contact electrostatic printing engine operable in a novel fashion upon a copy substrate, for imaging and development of a latent image representative of the image, and subsequent transfer of the developed image to the copy substrate. The developed image is created by separating and selectively transferring portions of a high solids content toner cake layer in correspondence with the image and non-image regions of the latent image. A toner cake layer delivery apparatus draws from a supply of low solids content liquid developing material to apply a layer of the liquid developing material onto a carrier fluid separation (CFS) surface of a coating member. Rapid migration of the carrier fluid into the CFS surface causes a substantial reduction of the ratio of carrier fluid to toner solids, thus providing the desired high solids content toner cake layer.

Complex animations that successively illustrate multiple constraint graph paths are possible.

Abstract: A method detects if an image is compressed. The method determines a block grid within the image and establishes blocks from the determined grid. The method then computes differences between samples inside the established blocks and differences between samples across the established blocks. The method determines that the image is compressed based on characteristics derived from statistics of the computed differences.
