Class CIFilter

  • All Implemented Interfaces:
    NSCoding, NSCopying, NSSecureCoding, NSObject
    public class CIFilter
extends NSObject
implements NSSecureCoding, NSCopying
    CIFilter are filter objects for Core Image that encapsulate the filter with its attributes The CIFilter class produces a CIImage object as output. Typically, a filter takes one or more images as input. Some filters, however, generate an image based on other types of input parameters. The parameters of a CIFilter object are set and retrieved through the use of key-value pairs. You use the CIFilter object in conjunction with the CIImage, CIContext, CIVector, CIImageAccumulator, and CIColor objects to take advantage of the built-in Core Image filters when processing images. CIFilter objects are also used along with CIKernel, CISampler, and CIFilterShape objects to create custom filters.

The parameters of other filter classes will not be serialized. The return value will be null if none of the filters can be serialized.
