public class GaussianFilter
extends ConvolveFilter

A filter which applies Gaussian blur to an image. This is a subclass of ConvolveFilter which simply creates a kernel with a Gaussian distribution for blurring.

Constructor Detail

GaussianFilter

public GaussianFilter()

Construct a Gaussian filter

GaussianFilter

public GaussianFilter(int radius)

Construct a Gaussian filter

Parameters:

radius - blur radius in pixels

Method Detail

setRadius

public void setRadius(int radius)

Set the radius of the kernel, and hence the amount of blur. The bigger the radius, the longer this filter will take.

Parameters:

radius - the radius of the blur in pixels.

getRadius

public int getRadius()

Get the radius of the kernel.

Returns:

the radius

imageComplete

public void imageComplete(int status)

DOCUMENT ME!

Specified by:

imageComplete in interface java.awt.image.ImageConsumer

Overrides:

imageComplete in class ConvolveFilter

Parameters:

status - DOCUMENT ME!

makeKernel
