Fields

Name	Description
ApproxNone	CHAIN_APPROX_NONE - translate all the points from the chain code into points;
ApproxSimple	CHAIN_APPROX_SIMPLE - compress horizontal, vertical, and diagonal segments, that is, the function leaves only their ending points;
ApproxTC89KCOS	CHAIN_APPROX_TC89_KCOS - apply one of the flavors of Teh-Chin chain approximation algorithm.
ApproxTC89L1	CHAIN_APPROX_TC89_L1 - apply one of the flavors of Teh-Chin chain approximation algorithm.
