An abstract class that is the base for convolution filters.
public abstract class CIConvolutionCore : CoreImage.CIFiltertype CIConvolutionCore = class
inherit CIFilter- Inheritance
- Derived
Remarks
Convolution filters generate a pixel value by summing the pixel values in a neighborhood (the size of the neighborhood may be 3x3, 5x5, or 9 pixels horizontally or vertically) and then by adding a bias. To maintain brightness, the sum of values in the convolution kernel must sum to 1.0.
Constructors
| Name | Description |
|---|---|
| CIConvolutionCore(NativeHandle) |
A constructor used when creating managed representations of unmanaged objects. Called by the runtime. |
| CIConvolutionCore(NSCoder) |
A constructor that initializes the object from the data stored in the unarchiver object. |
| CIConvolutionCore(NSObjectFlag) |
Constructor to call on derived classes to skip initialization and merely allocate the object. |
| CIConvolutionCore(String) |
Creates a new CIConvolutionCore with the specified name. |
