Package Summary  Overview Summary

class:Kernel [NONE]
All Implemented Interfaces:
Cloneable 
public class Kernel
extends Object
implements 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.

constructor:Kernel(int,int,float[]) [NONE]

  • 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.
    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

method:getXOrigin() [NONE]

  • getXOrigin

    public final  int getXOrigin()
    Returns the X origin of this Kernel.
    Returns:
    the X origin.

    • method:getYOrigin() [NONE]

    getYOrigin

    public final  int getYOrigin()
    Returns the Y origin of this Kernel.
    Returns:
    the Y origin.

    method:getWidth() [NONE]

    getWidth

    public final  int getWidth()
    Returns the width of this Kernel.
    Returns:
    the width of this Kernel.

    method:getHeight() [NONE]

    getHeight

    public final  int getHeight()
    Returns the height of this Kernel.
    Returns:
    the height of this Kernel.

    method:getKernelData(float[]) [NONE]

    getKernelData

    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.
    Parameters:
    data - if non-null, contains the returned kernel data
    Returns:
    the 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
    Throws:
    IllegalArgumentException - if data is less than the size of this Kernel

    method:clone() [NONE]

    clone

    public Object clone()
    Clones this object.
    Overrides:
    clone in class Object
    Returns:
    a clone of this object.
