  • 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 Detail

  • getXOrigin

    public final int getXOrigin()

    Returns the X origin of this Kernel.

    Returns:

    the X origin.

  • getYOrigin

    public final int getYOrigin()

    Returns the Y origin of this Kernel.

    Returns:

    the Y origin.

  • getWidth

    public final int getWidth()

    Returns the width of this Kernel.

    Returns:

    the width of this Kernel.

  • getHeight

    public final int getHeight()

    Returns the height of this Kernel.

    Returns:

    the height of this Kernel.

  • 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

  • clone

    public Object clone()

    Clones this object.

    Overrides:

    clone in class Object

    Returns:

    a clone of this object.
