UnsharpFilter

public UnsharpFilter()

Method Detail

setRadius

public void setRadius(float radius)

Description copied from class: GaussianFilter

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

Overrides:

setRadius in class GaussianFilter

Parameters:

radius - the radius of the blur in pixels.

setThreshold

public void setThreshold(int threshold)

getThreshold

public int getThreshold()

setAmount

public void setAmount(float amount)

getAmount

public float getAmount()

filter

public java.awt.image.BufferedImage filter(java.awt.image.BufferedImage src,
                                           java.awt.image.BufferedImage dst)

Specified by:

filter in interface java.awt.image.BufferedImageOp

Overrides:

toString

public java.lang.String toString()

Overrides:
