摘要： A system and method for generating a lattice of points that respects features in a digital image. The method comprises a process for initializing the lattice, and a process for optimizing the configuration of that lattice with respect to the image features. The optimization process operates by adjusting points of the lattice to extremize a composite function of the spatial coordinates of the lattice points. The lattice points are interpreted as atoms. Each lattice point contributes a potential function to an atomic potential field. The image represents another potential field. The composite function is a weighted sum of the atomic and image potential fields evaluated at the lattice points.

摘要： A print engine controller for a pagewidth printhead includes contone and bi-level decompression circuitry for decompressing a contone layer of compressed page data and a bi-level layer of compressed page data, respectively; halftoner and compositor circuitry for halftoning the decompressed contone layer to associated bi-level versions and compositing the decompressed bi-level layer over the halftoned contone layers; printhead interface circuitry for receiving the halftoned and composited data, and to generate therefrom print data suitable for printing by the printhead; and line loader and formatter circuitry for receiving dot data from the halftoner and compositor circuitry, loading dot data for a given print line into buffer storages, and formatting the dots of the given print line into an order required by the printhead interface circuitry. The line loader and formatter circuitry loads the dot data into a combination of on integrated circuit and external storage buffers.

摘要： An embodiment of the present invention is an apparatus to filter two-dimensional (2-D) data. A first filter processes two-dimensional (2-D) data in a block of pixels in a first dimension for a plurality of filter sizes. The block has a swath. A register file stores the 2-D data based on programmable information. A second filter filters the stored 2-D data in a second dimension to generate filter outputs in one of static and dynamic modes based on the programmable information. The static mode leaves the filter outputs fixed for the swath and the dynamic mode selects the filter outputs on a pixel basis. The filter outputs include first and second filter outputs.
