Class DilateFilter

Implemented Interfaces:
BufferedImageOp, Cloneable
public class DilateFilter
extends BinaryFilter
Given a binary image, this filter performs binary dilation, setting all added pixels to the given 'new' color.

public DilateFilter()
Construct a WholeImageFilter.

Method Details

filterPixels

protected int[] filterPixels(int width,
                             int height,
                             int[] inPixels,
                             Rectangle transformedSpace)
Actually filter the pixels.
Overrides:
filterPixels in interface WholeImageFilter
Parameters:
width - the image width
height - the image height
inPixels - the image pixels
transformedSpace - the output bounds
Returns:
the output pixels

getThreshold

public int getThreshold()
Return the threshold - the number of neighbouring pixels for dilation to occur.
Returns:
the current threshold
See Also:
setThreshold(int)

setThreshold

public void setThreshold(int threshold)
Set the threshold - the number of neighbouring pixels for dilation to occur.
Parameters:
threshold - the new threshold
See Also:
getThreshold()

toString
