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 system to convert an image described in a page description language to a contone image. The contone image is halftoned and encoded to generate image data including edge tag data and image data. A tagged state value of each pixel of image data within a predefined neighborhood of pixels is determined. The image data is filtered using a predetermined set of filter weighting values wherein each pixel of image data within the predefined neighborhood of pixels has an associated filter weighting value. A predetermined filtered image value is assigned to each pixel having a tagged state indicating an edge pixel. A summation of all filtered image values for the predefined neighborhood of pixels is assigned when the tagged state of the pixel is a non-edge pixel.
