Abstract: Sets of pixel data defining parts of rasterized portions of an image are received. At least one of the parts of one of the rasterized portions of the image overlaps another part of that portion of the image. The pixel data that defines the overlapping part includes mask data that identifies pixels of the overlapping part that are to be included in the image. The sets of pixel data are decompressed. The decompressed data are used to generate a series of the rasterized portions of the image including the pixels identified in the mask data. While each of the rasterized portions of the image is being used by a print engine, another of the rasterized portions of the series is being generated.

Abstract: Cable tester and methods of operating the same for subjecting cable such as mining cable to simulated conditions substantially corresponding to actual field conditions as normally encountered by the cable for determining cable longevity, comprisinga surface having first and second spaced apart reference points and defining a test drag surface area therebetween,a source adjacent the second point for feed and return of a test span of the cable,first and second moving mechanisms, the first mechanism being connectable to the cable for moving the forward end of the test span from the second to the first point and the second mechanism being connectable to the cable for moving the rearward end of the test span from the second point to the source, anda control system for controlling the first and second mechanisms,for operation in a first test mode for simultaneous reciprocal movement of both mechanisms to drag the test span back and forth along the drag surface area to simulate corresponding field condition dragging
