Method Detail

componentsMerged

public void componentsMerged(Component c1,
                             Component c2)

Called when component c2 is merged into component c1. This will be called before the merge occurs, so component c1 will not contain the pixels of c2.

Specified by:

componentsMerged in interface ComponentStackMergeListener

Parameters:

c1 - The component that is receiving the merge

c2 - The component that is providing the merge.

componentPromoted

public void componentPromoted(Component c1)

Called when the given component c1 is upwardly promoted to a higher intensity value. The component will contain all the pixels at the higher level.

Specified by:

componentPromoted in interface ComponentStackMergeListener

Parameters:

c1 - The component being promoted.

getTree

public TreeNode<Component> getTree()

Return the tree that has been built.

Returns:

the tree
