Abstract

Typically, the user specifies an area or window on which image processing functions are to be performed by entering coordinants of a rectangular area. These coordinants identify the corner pixels of the rectangle wherein the coordinant represents a scanline and a pixel (SL, PX). A window control function then decodes the coordinants by counting scanlines and pixels and turning ON the desired functions when the image processing operations encounters the initial pixel at the upper-most left corner of the rectangular window. Moreover, the window control function turns OFF the desired functions when the image processing operations depart the rectangular window.
