Abstract: Disclosed is a method (2500) of determining, for a rendering job (2402) comprising one or more page building jobs, a start time for a print engine (195) to print the rendering job (2402), the method including determining (2502) for the rendering job a current start time for printing based on at least a predicted finishing time of a page building job, determining (2503) a difference between the predicted finishing time and an actual finishing time of the page building job, determining (2504) if, based on the difference, a predetermined condition is satisfied, and if the predetermined criterion is satisfied, determining (2505) an updated start time for printing the rendering job based on information relating to the actual finishing time of the page building job, and starting (2509) the print engine to print the rendering job at the updated start time.

Abstract: Disclosed is a method of rasterizing a page comprising a plurality of graphic objects. The method obtains a plurality of pixel-aligned object edges (302,303) of the graphic objects (203), and determining a pixel generation path (402) for the plurality of graphic objects. The method determines a plurality of crossing locations (420-424) based on the pixel aligned object edges and the pixel generation path, at least one of the crossing locations being a vertical crossing location and at least one other crossing location being a horizontal crossing location, rasterizes the page according to the pixel generation path by updating a fill sequence (620-623) upon encountering said determined crossing locations.

Abstract: A method (700) of storing a bitmap is disclosed. The method (700) examines a transform matrix of a representation of the bitmap to determine a scaling factor required for rendering the bitmap. A range of spectral coefficients is determined based on the scaling factor. Each range of spectral coefficients is entropy encoded into separate bitstreams representing the bitmap. The bitstreams are stored in a computer memory (106).

Abstract: Disclosed is a variable-length image compression arrangement which represents successive distinct image data values (220, 221) of an image using corresponding non-decreasing Palette values (215, 222), and which incorporates (915, 1025) into the encoded data stream information recording the position in the encoded data stream at which each Palette value bit representation length increase occurs.

Abstract: Disclosed is method of encoding a set of data values (205-245). Each data value corresponds to a pixel position (205,210, 220,225) within an image (100). The method operates on a current (230) said data value at a current pixel position. The method creates (605) a context set (215,225) for the data value (230), the context set including a data value at a pixel position (225) in the set immediately preceding the current pixel position in an encoding order, wherein the immediately preceding pixel position is not adjacent said current pixel position within said image. The method then encodes (500) the data value (230) using the created context set (215,225). A corresponding decoding method is also provided.

Abstract: 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.

Abstract: The cap assembly of a turbine combustor includes a plurality of burner tubes sealed against fuel nozzles extending in the tubes. These piston seals are coated with a high velocity oxygen fuel coating to extend their service life. The outer cap body assembly includes concentric seal rings each with cantilevered convex fingers circumferentially offset from one another to seal between the cap assembly casing and the inner liner. The cap assembly casing is provided with a plurality of holes at predetermined locations about the casing to minimize or eliminate response to combustion dynamics.

Abstract: A fuel nozzle assembly for a gas turbine includes a plurality of circumferentially spaced vanes with holes for flowing fuel from plenums within the vanes through holes in the vane walls for premixing with air. To tune the nozzle assembly, the holes are resized by reforming the existing holes to a predetermined hole size, securing plugs into the holes, and forming holes through at least certain of the plugs to diameters less than the diameter of the existing holes.
