Abstract:
1. A method of edge-smoothing in raster images, the method comprising the steps of: (a) selecting an object in a raster image, said object including an edge having a plurality of edge pixels; (b) finding all of said edge pixels of said object and generating a polygon having a plurality of vertices, each of which is located at the center of a corresponding one of said edge pixels; (c) smoothing said polygon of said object to generate a smoothed polygon by comparing a first number of polygon vertices in a first position to a second number of polygon vertices in a second position, wherein said first and second numbers of vertices are in a substantially horizontal or vertical linear arrangement, and changing the positions of said vertices in the smaller of said first and second numbers of vertices to the positions of the larger of said first and second numbers of vertices; and (d) smoothing said object according to said smoothed polygon.
