Classes
class	point2< T >
	2D point both axes of which have the same dimension typeModels: Point2DConcept More...
struct	deref_base< ConstT, Value, Reference, ConstReference, ArgType, ResultType, IsMutable >
	Helper base class for pixel dereference adaptors. More...
class	deref_compose< D1, D2 >

	identity taken from SGI STL. More...
struct	plus_asymmetric< T1, T2 >
	plus function object whose arguments may be of different type. More...
struct	inc< T >
	operator++ wrapped in a function object More...
struct	dec< T >
	operator– wrapped in a function object More...
struct	type_to_index< Types, T >
	Returns the index corresponding to the first occurrance of a given given type in. More...
struct	layout< ColorSpace, ChannelMapping >
	Represents a color space and ordering of channels in memory. More...
