Constructs a Kernel object from an array of floats. The first width*height elements of the data array are copied. If the length of the data array is less than width*height, an IllegalArgumentException is thrown. The X origin is (width-1)/2 and the Y origin is (height-1)/2.

Parameters:

width - width of the kernel

height - height of the kernel

data - kernel data in row major order

Throws:

IllegalArgumentException - if the length of data is less than the product of width and height

            // this shouldn't happen, since we are Cloneable
            throw new InternalError();
        }
}

Clones this object.

 public final int getHeight() 
{
        return height;
}

Returns the height of this Kernel.

        System.arraycopy(this.data, 0, data, 0, this.data.length);
        return data;
}

Returns the kernel data in row major order. The data array is returned. If data is null, a new array is allocated.

 public final int getWidth() 
{
        return width;
}

Returns the width of this Kernel.

 public final int getXOrigin() 
{
        return xOrigin;
}

Returns the X origin of this Kernel.

 public final int getYOrigin() 
{
        return yOrigin;
}

Returns the Y origin of this Kernel.
