class CISamplerOverview
The CISampler class retrieves samples of images for processing by a CIKernel object. A CISampler object defines a coordinate transform, and modes for interpolation and wrapping. You use CISampler objects in conjunction with other Core Image classes, such as CIFilter, CIKernel, and CIFilterShape, to create custom filters.
