Cloneable
The 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.
Constructors
Kernel(int width, int height, float[] data)
Constructs a Kernel object from an array of floats.
final int
Returns the height of this Kernel.
final float[]
Returns the kernel data in row major order.
final int
Returns the width of this Kernel.
final int
Returns the X origin of this Kernel.
final int
Returns the Y origin of this Kernel.
public Kernel(int width, int height, float[] data)
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.
width - width of the kernel
height - height of the kernel
data - kernel data in row major order
IllegalArgumentException - if the length of data is less than the product of width and height
public final int getXOrigin()
Returns the X origin of this Kernel.
public final int getYOrigin()
Returns the Y origin of this Kernel.
public final int getWidth()
Returns the width of this Kernel.
Kernel.
public final int getHeight()
Returns the height of this Kernel.
Kernel.
public final float[] getKernelData(float[] data)
Returns the kernel data in row major order. The data array is returned. If data is null, a new array is allocated.
data - if non-null, contains the returned kernel data
data array containing the kernel data in row major order or, if data is null, a newly allocated array containing the kernel data in row major order
IllegalArgumentException - if data is less than the size of this Kernel
Clones this object.
