Kernel JDK 1.6)

Description

public class Kernel

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 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

public Kernel (int width, int height, float[] data)

Constructs a Kernel object from an array of floats.

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

Methods

Hide/Show inherited methods

public Object clone ()

Clones this object.

publicfinal int getHeight ()

Returns the height of this Kernel.

Returns the height of this Kernel.
Returns: the height of this Kernel.

publicfinal float getKernelData (float[] data)

Returns the kernel data in row major order.

Returns the kernel data in row major order.
The data array is returned. If data
is null, a new array is allocated.
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
Parameters:
- data - if non-null, contains the returned kernel data
Throws:
- IllegalArgumentException - if data is less than the size of this Kernel

publicfinal int getWidth ()

Returns the width of this Kernel.

Returns the width of this Kernel.
Returns: the width of this Kernel.

publicfinal int getXOrigin ()

Returns the X origin of this Kernel.

Returns the X origin of this Kernel.
Returns: the X origin.

publicfinal int getYOrigin ()

Returns the Y origin of this Kernel.

Returns the Y origin of this Kernel.
Returns: the Y origin.
