摘要： Systems, methods, and software for halftoning. In an embodiment, a halftone system is configured to store a threshold array comprising an array of threshold elements. The halftone system is further configured to receive a source image comprising an array of pixels with pixel values, and perform a multi-level halftoning process on the source image by partitioning the source image into a sequence of image segments, partitioning the threshold array into a plurality of threshold segments, identifying image segment groups each comprising a set of the image segments that are noncontiguous in the sequence and correspond with a mutual threshold segment of the threshold array, and schedule processing of the image segments in an image segment group as a batch based on the mutual threshold segment.
