Class FloodFiller

java.lang.Object

net.imagej.FloodFiller

public class FloodFiller
extends Object

This class, which does flood filling, is used by the FloodFillTool. It was adapted from legacy ImageJ's FloodFiller class. That class implements the flood filling code used by legacy ImageJ's macro language and legacy ImageJ's particle analyzer. The Wikipedia article at "http://en.wikipedia.org/wiki/Flood_fill" has a good description of the algorithm used here as well as examples in C and Java.

Constructor Detail

FloodFiller

public FloodFiller(DrawingTool tool)

Constructs a FloodFiller from a given DrawingTool. The FloodFiller uses the DrawingTool to fill a region of contiguous pixels in a plane of a Dataset.

Method Detail

fill4

public boolean fill4(long u0,
                     long v0,
                     long[] position)

Does a 4-connected flood fill using the current fill/draw value. Returns true if any pixels actually changed and false otherwise.

fill8

public boolean fill8(long u0,
                     long v0,
                     long[] position)

Does an 8-connected flood fill using the current fill/draw value. Returns true if any pixels actually changed and false otherwise.

particleAnalyzerFill

public void particleAnalyzerFill(long u0,
                                 long v0,
                                 long[] position,
                                 double level1,
                                 double level2,
                                 DrawingTool maskTool,
                                 RealRect bounds)

In IJ1 this method is used by the particle analyzer to remove interior holes from particle masks.
