摘要： An embodiment generally relates to systems and methods for determining a conversion location based on the content of a document and an intended quality level of the document. More particularly, processing logic can be configured to analyze a document submitted for rendering to determine a content level of the document. Further the processing logic can compare the content level to an intended quality level specified by a user of the document to determine whether to convert the document on local resources or in a cloud-based network. An associated conversion application in the appropriate location can convert the document into a printable format, and a print engine can render the converted document.

摘要： Systems and methods are described that facilitate dominant point detection for text in a scanned document. The dominant points are classified as “major” (e.g., structural) and “minor” (e.g., serif). A set of rules or parameters for each character is determined off-line. During the text vectorization, OCR is performed and the rules (parameters) associated with the recognized character are selected. Both major and minor dominant points are detected as a maximization process with the parameter set. For minor dominant points, additional processes are optionally employed.

摘要： A method of printing comprising setting a pixel black value of K for an ink limit and identifying each of black dots of a first subset of black dots having pixel black value K greater than the ink limit, and pixel color value of cyan, magenta, and yellow equal to zero. The method further comprises rendering only K for a pixel value for the first subset of black dots and replacing each of black dots of a second subset of black dots of a halftoned bit map for a predetermined area with a process black dot. The method still further comprises adding a non-black dot to each of black dots of a third subset of black dots of the bit-mapped data, wherein the halftoned bit map is generated by halftoning continuous tone data; wherein the black dots of the third subset comprises a percentage of all the black dots that tends to generally increase as a ratio of black coverage to total coverage in the predetermined area increases; wherein the first, second, and third subset comprises black dots that are mutually exclusive; and, printing the bit map.

摘要： A system and method manages a file storage system by defining an arbitration policy, the arbitration policy defining a pre-defined usage level threshold and defining implementation priorities for a plurality of storage management mitigation actions, each storage management mitigation action defining a distinct action to be taken to reduce the usage level of the file storage system and a parameter for selecting which file or files stored in the file storage system qualify for the storage management mitigation action. If a usage level of the file storage system is greater than the pre-defined usage level threshold, a storage management mitigation action is selected from the plurality of storage management mitigation actions. Which files that qualify for the selected storage management mitigation action is determined and the selected storage management mitigation action is applied to the files determined to qualify for the selected storage management mitigation action to reduce the usage level of the file storage system.

摘要： A system electronically registers an image on an input document. The system includes a scanner for generating an image data stream representing an electronic image of the image on the input document and an edge detecting circuit for detecting edge data within the image data stream. A circuit detects a first corner of a leading edge of the input document based on the detected edge data and for establishing a first coordinate value therefrom and a second corner of a leading edge of the input document based on the detected edge data and for establishing a second coordinate value therefrom. The system further determines a minimum and maximum location for a leading edge of the scanned document and determines a minimum and maximum location for a trailing edge of the scanned document. An image window is generated representing valid image data to processed and rendered based on the minimum and maximum location for a leading edge of the scanned document, the minimum and maximum location for a trailing edge of the scanned document, the first coordinate value, and the second coordinate value.

摘要： A method and apparatus for controlling the execution of image processing operations carried out on an array of image signals, the specific operations having been identified by a plurality of predefined windows. The windows are divided into a plurality of non-overlapping tiles, the boundaries of which correspond to transitions from one window region to another. Each tile therefore defines an exclusive region within the array of image signals, and the image processing operations to be applied to the signals within the boundaries of that region. Tile data is stored in one of two memory banks, thereby enabling bank switching and reprogramming of the device in real-time to permit management of complex window shapes. The apparatus is designed to efficiently manage the identification of tile regions while minimizing the required decoding hardware. The apparatus also provides flexibility of programming resulting in greater efficiency of memory usage.
