protected void filter(CoreImage input, CoreImage output)
Filter
This method is called from Filter.getOutput()
if Filter.isDirty()
returns true.
The output image will be the same dimensions as
(Filter.getWidth()
x Filter.getHeight()
. Implementors must ensure
that every pixel in output
is drawn.

public Filter copy()
Filter
This method is used by the Sprite class. Most apps will not need to call this method.
Subclasses should bind all properties of the cloned object using bindWithInverse(). For example, for the HSBAdjust filter:
public Filter copy() { HSBAdjust copy = new HSBAdjust(); copy.hue.bindWithInverse(hue); copy.brightness.bindWithInverse(brightness); copy.saturation.bindWithInverse(saturation); return copy; }
