Actionscript Class to trace bitmap lines to vector lines

Summary I require a Class for a prototype application (Flex, Air) to dynamically trace a 1 pixel bitmap line and produce a vector string output (see below). More Detail I have a bitmap image with various dynamically drawn closed shapes. You can always assume the following :- The background is always transparent (or white if needed) The lines are always 1 pixel and black The shapes are always closed (it's originally created by the glow filter) Output The output will be sent to a plotter. The output lines must be smooth but accurate and the various shapes must be closed. Using only 'lineTo' and not 'curveTo' will NOT work as it creates a jagged edge. Using illustrators 'livetrace' on a 1 pixel size creates a very good smooth line on the shapes. I'm looking to replicate this as much as possible. Output Example.
