public class Kernel extends Object implements Cloneable
Kernel class defines a matrix that describes how a specified pixel and its surrounding pixels affect the value computed for the pixel's position in the output image of a filtering operation. The X origin and Y origin indicate the kernel matrix element that corresponds to the pixel position for which an output value is being computed.
public Kernel(int width, int height, float data)
Kernel object from an array of floats. The first
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.
width- width of the kernel
height- height of the kernel
data- kernel data in row major order
IllegalArgumentException- if the length of
datais less than the product of
public final int getXOrigin()
Returns the X origin of this
public final int getYOrigin()
Returns the Y origin of this
public final int getWidth()
Returns the width of this
public final int getHeight()
Returns the height of this
public final float getKernelData(float data)
Returns the kernel data in row major order. The
data array is returned. If
null, a new array is allocated.
data- if non-null, contains the returned kernel data
dataarray containing the kernel data in row major order or, if
null, a newly allocated array containing the kernel data in row major order
datais less than the size of this
