Constructor Detail

GaussianBlurFilter

public GaussianBlurFilter()

Creates a new blur filter with a default radius of 3.

GaussianBlurFilter

public GaussianBlurFilter(int radius)

Creates a new blur filter with the specified radius. If the radius is lower than 0, a radius of 0.1 will be used automatically.

Parameters:

radius - the radius, in pixels, of the blur

Method Detail

getRadius

public int getRadius()

Returns the radius used by this filter, in pixels.

Returns:

the radius of the blur

filter

public BufferedImage filter(BufferedImage src,
                            BufferedImage dst)

Performs a single-input/single-output operation on a BufferedImage. If the color models for the two images do not match, a color conversion into the destination color model is performed. If the destination image is null, a BufferedImage with an appropriate ColorModel is created.

An IllegalArgumentException may be thrown if the source and/or destination image is incompatible with the types of images $ allowed by the class implementing this filter.

Specified by:

filter in interface BufferedImageOp

Specified by:

filter in class AbstractFilter

Parameters:

src - The BufferedImage to be filtered

dst - The BufferedImage in which to store the results$

Returns:

The filtered BufferedImage.
