Class ContourJoiner

java.lang.Object

net.algart.contours.ContourJoiner

public final class ContourJoiner
extends Object

Joiner of contours.

Note that this class guarantees full 100% joining of only 4-connected contours (external and internal). Contours of 8-connected objects, in some situations, are not joined completely. It allows to use more simple and efficient algorithm with a guarantee that it will not require a lot of memory (more than necessary for storing results and the largest matrix, necessary for "drawing" any source contour).
