java.lang.Object | +--java.awt.image.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 orderdata
is less than the product of width
and
height
