 java.awt.image.Kernel
| Kernel | | public class Kernel implements Cloneable(Code) | | 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 Summary | |
| public | Kernel(int width, int height, float data)
Constructs a Kernel object from an array of floats. |
| Method Summary | |
| public Object | clone()
Clones this object. | | final public int | getHeight()
Returns the height of this Kernel. | | final public float[] | getKernelData(float[] data)
Returns the kernel data in row major order. | | final public int | getWidth()
Returns the width of this Kernel. | | final public int | getXOrigin()
Returns the X origin of this Kernel. | | final public int | getYOrigin()
Returns the Y origin of this Kernel. |
| Kernel | | public Kernel(int width, int height, float data)(Code) | | 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
Parameters:
height - height of the kernel
Parameters:
data - kernel data in row major order
throws:
IllegalArgumentException - if the length of datais less than the product of width and height |
| clone | | public Object clone()(Code) | | Clones this object.
a clone of this object. |
| getHeight | | final public int getHeight()(Code) | | Returns the height of this Kernel.
the height of this Kernel. |
| getKernelData | | final public float[] getKernelData(float[] data)(Code) | | 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 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 lessthan the size of this Kernel |
| getWidth | | final public int getWidth()(Code) | | Returns the width of this Kernel.
the width of this Kernel. |
| getXOrigin | | final public int getXOrigin()(Code) | | Returns the X origin of this Kernel.
the X origin. |
| getYOrigin | | final public int getYOrigin()(Code) | | Returns the Y origin of this Kernel.
the Y origin. |
