CIVector

The Core Image class that defines a vector object.

Declaration

class CIVector

Overview

A CIVector can store one or more CGFloat in one object. They can store a group of float values for a variety of different uses such as coordinate points, direction vectors, geometric rectangles, transform matrices, convolution weights, or just a list a parameter values.

You use CIVector objects in conjunction with other Core Image classes, such as CIFilter and CIKernel. Many of the built-in Core Image filters have one or more CIVector inputs that you can set to affect the filter’s behavior.
