java.lang.Objectjava.awt.image.Kernel
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 X origin and Y origin indicate the kernel matrix element
that corresponds to the pixel position for which an output value is
being computed.

public Kernel(int width,
int height,
float[] data)
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 kernelheight - height of the kerneldata - kernel data in row major order
IllegalArgumentException - if the length of data
is less than the product of width and
height| Method Detail |
