Abstract
Methods, and apparatus, including computer programs, implement techniques for generating a polygon from a bitmap object. Boundary pixels of the bitmap object are identified. A boundary pixel is an object pixel that shares an edge with a non-object pixel or a non-object pixel that shares an edge with an object pixel. All perimeter edge line segments are identified for each identified boundary pixel. A perimeter edge line segment is an edge line segment that separates an object pixel from a non-object pixel. The identified perimeter edge line segments are accumulated to define a polygon.
