# Models
[Pixel Dereference Adaptor]

## Classes

class | color_convert_deref_fn
| Function object that given a source pixel, returns it converted to a given color space and channel depth. Models: PixelDereferenceAdaptorConcept. More...
struct | nth_channel_deref_fn
| Function object that returns a grayscale reference of the N-th channel of a given reference. Models: PixelDereferenceAdaptorConcept. If the input is a pixel value or constant reference, the function object is immutable. Otherwise it is mutable (and returns non-const reference to the n-th channel). More...
struct | kth_channel_deref_fn
| Function object that returns a grayscale reference of the K-th channel (specified as a template parameter) of a given reference. Models: PixelDereferenceAdaptorConcept. If the input is a pixel value or constant reference, the function object is immutable. Otherwise it is mutable (and returns non-const reference to the k-th channel). More...
struct | deref_base
| Helper base class for pixel dereference adaptors. More...
class | deref_compose
| Composes two dereference function objects. Similar to std::unary_compose but needs to pull some typedefs from the component types. Models: PixelDereferenceAdaptorConcept. More...
