Class Kernel
- Cloneable
Kernel represents an image processing kernel. It gets used to hold
convolution filters among other purposes. It stores an array of float
values representing a 2-dimensional array in row-major order.
Kernel(int width, int height, float[] data)- Creates a new
Kernel instance with the specified dimensions
and values.
|
Object | clone()- Returns a clone of this kernel.
|
int | getHeight()- Returns the kernel height (as supplied to the constructor).
|
float[] | getKernelData(float[] data)- Returns an array containing a copy of the kernel data.
|
int | getWidth()- Returns the kernel width (as supplied to the constructor).
|
int | getXOrigin()- Returns the x-origin for the kernel, which is calculated as
(width - 1) / 2.
|
int | getYOrigin()- Returns the y-origin for the kernel, which is calculated as
(height - 1) / 2.

Kernel
public Kernel(int width,
int height,
float[] data)
throws IllegalArgumentException Creates a new Kernel instance with the specified dimensions
and values. The first width * height values in the specified
data array are copied to internal storage.
width - the kernel width.height - the kernel height.data - the source data array (null not permitted).
getHeight
public final int getHeight()
Returns the kernel height (as supplied to the constructor).
getKernelData
public final float[] getKernelData(float[] data)
throws IllegalArgumentException Returns an array containing a copy of the kernel data. If the
data argument is non-null, the kernel values
are copied into it and then data is returned as the result.
If the data argument is null, this method
allocates a new array then populates and returns it.
data - an array to copy the return values into (if
null, a new array is allocated).
- The array with copied values.
getWidth
public final int getWidth()
Returns the kernel width (as supplied to the constructor).
getXOrigin
public final int getXOrigin()
Returns the x-origin for the kernel, which is calculated as
(width - 1) / 2.
- The x-origin for the kernel.
getYOrigin
public final int getYOrigin()
Returns the y-origin for the kernel, which is calculated as
(height - 1) / 2.
- The y-origin for the kernel.
