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
};
