ABSTRACT:
A method for determining whether a particular cell of an array of display cells, either of full pixels or subpixel portions, is interior or exterior to a circular feature of non-zero radius, uses a line segment length L measured from the vertical feature diameter to the feature periphery, along a point of each row of cells to be considered. For that cell row, all cells within L cells of the vertical diameter line are within the feature; the number of cells on each row changes as the row position changes with respect to the centroid.
