ShadowFilter

public ShadowFilter()

ShadowFilter

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

Method Detail

setXOffset

public void setXOffset(int xOffset)

getXOffset

public int getXOffset()

setYOffset

public void setYOffset(int yOffset)

getYOffset

public int getYOffset()

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

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)
