Declaration
enum MPSImageFeatureChannelFormat : UInt
Overview
A pixel in an MPSImage object may have many channels in it, sometimes many more than 4, that exceed the limit of what a MTLPixel value can encode. The storage format for a single channel within a pixel can be given by the MPSImage type. The number of channels is defined by the feature property of an MPSImage object. The size of the pixel is the size of the channel format multiplied by the number of feature channels. No padding is allowed, except to round out to a full byte.
