## Classes
struct | nth_channel_view_type
| Given a source image view type View, returns the type of an image view over a single channel of View If the channels in the source view are adjacent in memory (such as planar non-step view or single-channel view) then the return view is a single-channel non-step view. If the channels are non-adjacent (interleaved and/or step view) then the return view is a single-channel step view. More...
struct | nth_channel_view_type< any_image_view< ViewTypes > >
| Given a runtime source image view, returns the type of a runtime image view over a single channel of the source view. More...
