Detailed Description

Represent a 2D path as a sequence of connected image index offsets.

This class is intended to represent sequences of connected indices in a 2D image plane. It does so by storing the offset of each index from its immediately preceding, connected, index using a standard Freeman code (1=up, 2=up to the right, and so on proceeding clockwise to 8=up to the left). The only image index stored directly is that of the first index. ChainCodePath2D maps a 1D integer input (step number) to a 2D integer output (either an offset or an image index, depending on whether Evaluate or EvaluateToIndex is called).
