o getWidth 
public final int getWidth()
Returns the width

o getHeight 
public final int getHeight()
Returns the height

o getKernelData 
public final float[] getKernelData(float[] data)
Returns the kernel data in row major order.

Parameters:
data - If non-null, will contain the returned kernel data.
