Abstract: Rapid throughput of still image compressed data (e.g. JPEG) is achieved for presentation of images in rapid succession for browsing or browsing by panning within large images by using a hardware decoder adapted for presentation of moving images to reduce the processing load which must be performed in accordance with software although the still image data is incompatible with still image data in many respects; some of which necessarily lead to a loss of image fidelity. The still image data is partially decoded (e.g. entropy decoded) in software processing and re-encoded and reformatted to a form which can at least be accepted by the hardware decoder even though not compliant with any particular moving picture data standard (e.g. MPEG). Storage in the hardware decoder is reallocated to provide, in combination with a reduction of slower software processing, a throughput increase of four-fold or more. Software processing of the still image data is also allowed to proceed and the result substituted for the result of the hardware decoding if a given image is viewed for a time sufficient for the software image processing to be completed.

Abstract translation: 实现静止图像压缩数据（例如JPEG）的快速吞吐量，用于通过使用适于呈现运动图像的硬件解码器来快速连续地呈现图像以浏览或浏览大图像中的平移，以减少必须执行的处理负载 根据软件虽然静止图像数据在许多方面与静止图像数据不兼容; 其中一些必然导致图像保真度的丧失。 静止图像数据在软件处理中被部分解码（例如熵解码），并被重新编码并重新格式化为至少可被硬件解码器接受的形式，即使不符合任何特定的运动图像数据标准（例如MPEG）。 重新分配硬件解码器中的存储，结合减少较慢的软件处理，吞吐量增加四倍或更多。 静止图像数据的软件处理也被允许进行，并且如果给定图像被观看足以使软件图像处理完成的时间，则结果代替硬件解码的结果。

Abstract: The present invention allows data objects to be tagged with secondary resources that specify rendering attributes, such as color profiles. A method, data structure and apparatus provides object level management using tagged secondary resources. Rendering control (color space selection, in this case) of the primary datastream (AFP, in this case) is provided to heterogeneous objects (PostScript Level 1 color images, in this case). The present invention provides a method for the primary datastream to include the source calibration parameters, i.e., the rendering control, without modifying the heterogeneous object. For example, if the threshold matrix for the halftoning is tagged as a resource to the image object, the rendering process can use this specific matrix when the image is halftoned and presented.

Abstract: In summary, the present invention provides a method, apparatus and program product for calculating an estimate of the amount of toner coverage required for printing print data defined in a compressed data stream. The estimate is obtained with reduced processing by obtaining coverage data from a partially decompressed formed of the data stream and using this to obtain the coverage estimate, thus removing the need to do a full de-compression of the data stream. For example the coverage data is a count of toned pixels for at least one intensity level.

Abstract: Method and system aspects for mapping tasks to iteratively improve task assignment in a heterogeneous computing (HC) system include identifying a current machine that defines a makespan in the HC system. Further included is the reassigning of at least one task from the current machine to at least one alternate machine in the HC system according to a predefined reassignment constraint. Reassigning also includes reassigning the at least one task when the at least one alternate machine can perform the at least one task in addition to previously assigned work while finishing in less time than the time of the makespan reduced by time required for the task being reassigned.

Abstract: A method, system, and data structure for the scaling down of data is provided. At least two blocks of transformed data samples representing at least two blocks of original data samples are received. One of at least two tables of constants is selected wherein each table of constants is capable of reducing the number of transformed data samples by a different factor. The constants taken from the selected table are applied to the at least two blocks of transformed data samples to produce one block of transformed data samples representing one block of final data samples. The data is processed one dimension at a time by multiplying the data in one dimension with selected constants taken from previously developed tables corresponding to the desired scale down factor. Scaling down by different factors in each dimension as well as scaling down in one dimension and scaling up in the other dimension may be achieved. In addition, the de-quantization of the quantized transform coefficients may be accomplished by pre-multiplication of the selected constants when the quantization values are known. In a similar way the re-quantization may be accomplished by a pre-division of the selected constants. Both de-quantization and re-quantization may be combined when the input quantized transform coefficients and output quantized transform coefficients are desired.

Abstract: Image rotations of 90°, 180° and 270° and horizontal and vertical mirroring image transformations are performed losslessly and with greatly enhanced speed by processing orthogonal transform coefficients in a zig-zag order with direct storage of S (size) values, reassociated R (run of zero valued coefficients) from an adjacent coded orthogonal transform value and a non-zero valued transformation coefficient in reverse zig-zag order. Cache misses are avoided by processing values which are not widely separated in the coded data and other features of the technique and memory accesses are reduced to accelerate processing while extremely little computation is required. These effects are substantially augmented when intermediate codes having certain attributes including coding of zero valued coefficients and flagging certain code features are employed.
