Method Detail

findPointType

public PixelTypeCalculator findPointType(int pixelIndex,
                                         PixelTypeCalculator reusedPixelTypeCalculator)

From the current point find direction. A problem with finding maximum is that the neighbor might not be known. Should the maximum only be calculated among unused? I think that if you have a V point and a junction If I already know a pixel should I do the calculation again?
