Constructor Detail

ShadowFilter

public ShadowFilter()

ShadowFilter

public ShadowFilter(float radius,
                    float xOffset,
                    float yOffset,
                    float opacity)

Method Detail

setAngle

public void setAngle(float angle)

getAngle

public float getAngle()

setDistance

public void setDistance(float distance)

getDistance

public float getDistance()

setRadius

public void setRadius(float 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 float getRadius()

Get the radius of the kernel.

Returns:

the radius

setOpacity

public void setOpacity(float opacity)

getOpacity

public float getOpacity()

setShadowColor

public void setShadowColor(int shadowColor)

getShadowColor

public int getShadowColor()

setAddMargins

public void setAddMargins(boolean addMargins)

getAddMargins

public boolean getAddMargins()

setShadowOnly

public void setShadowOnly(boolean shadowOnly)

getShadowOnly

public boolean getShadowOnly()

transformSpace

protected void transformSpace(java.awt.Rectangle r)

filter

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