Kernel.
Library: ilvbmpflt
This class lets you manipulate kernels. A kernel is an m x n matrix. It is mainly used by the IlvConvolutionFilter
.
For the Arithmetic operator each pixel is computed as follows:
result = k1 * c1 * c2 + k2 * c1 + k3 * c2 + k4
k1, k2, k3, and k4 can be specified.
IlvBitmapDataKernel::IlvBitmapDataKernel | ( | ) |
Constructor.
Initializes a new instance of the class IlvBitmapDataKernel
.
Constructor.
Initializes a new instance of the class IlvBitmapDataKernel
using an array of floating point values.
width | The width (columns) of the kernel. |
height | The height (rows) of the kernel. |
values | An array of width x height values. |
Constructor.
Initializes a new instance of the class IlvBitmapDataKernel
using a string representing the values, separated by 'space' or ','. For example: "1 1 1 1 2 1 1 1 1" is a simple blurring kernel.
width | The width (columns) of the kernel. |
height | The height (rows) of the kernel. |
values | A string representing the values. |
|
virtual |
Destructor.
The destructor releases all the memory used by the instance.
