FloodFiller (ImageJ2 Javadocs 0-SNAPSHOT API)

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.

Modifier and Type	Method and Description
`boolean`	`fill4(long u0, long v0, long[] position)` Does a 4-connected flood fill using the current fill/draw value.
`boolean`	`fill8(long u0, long v0, long[] position)` Does an 8-connected flood fill using the current fill/draw value.

```
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.

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.
