Method and system using variable line width adjustment with reduced scan buffering that is compatible with antialiasing

摘要

A method and system compensates for the line width growth or shrinkage in an image rendering system that supports high-addressability. The amount of width adjustment can be a function of the line width. The method is applied after rendering, to the sub-pixel, bit patterns and is compatible with antialiasing and other sub-pixel rendering techniques such as half-bitting. The method and system also require less scan buffering for marker line width compensation than conventional methods. More specifically, the method and system require N+3 scans to detect and adjust widths up to N pixels for leading edges or trailing edges rather than the 2N+3 necessary conventionally. Moreover, the detection and adjustment of widths up to N pixels may be performed for both leading edges and trailing edges using a buffer that can handle 2N+3 scans.
