Remarks

On iOS 7.0, the following are the built-in filters:

Compositing Filters:

Affine Filters (CIAffineFilter):

Blend Filters (CIBlendFilter):

Compositing Filters (CICompositingFilter):

Convolution Filters (CIConvolutionCore):

Distortion Filters (CIDistortionFilter):

Photo Effects (CIPhotoEffect):

Transition Filters (CITransitionFilter):

Specialized Filters:

To create a filter of the specified type, instantiate an instance of one of the above types, assign values to their properties and extract the result by using the OutputImage property.


    var sepiaFilter = new CISepiaTone () {
    Image = mySourceImage,
    Intensity = 0.8f
    };

You can chain your filters as well:


    var sepiaFilter = new CISepiaTone () {
    Image = mySourceImage,
    Intensity = .8f
    };
    var invert = new CIColorInvert () {
    Image = sepia.OutputImage
    };

Constructors

CIFilter()

Creates a new CIFilter with default values.

CIFilter(IntPtr)

A constructor used when creating managed representations of unmanaged objects; Called by the runtime.

CIFilter(NSCoder)

A constructor that initializes the object from the data stored in the unarchiver object.
