Classes
struct	planar_pixel_iterator< ChannelPtr, ColorSpace >
	An iterator over planar pixels. Models HomogeneousColorBaseConcept, PixelIteratorConcept, HomogeneousPixelBasedConcept, MemoryBasedIteratorConcept, HasDynamicXStepTypeConcept. More...
class	memory_based_step_iterator< Iterator >
	MEMORY-BASED STEP ITERATOR. More...
class	memory_based_2d_locator< StepIterator >
	Memory-based pixel locator. Models: PixelLocatorConcept,HasDynamicXStepTypeConcept,HasDynamicYStepTypeConcept,HasTransposedTypeConceptThe class takes a step iterator as a parameter. The step iterator provides navigation along the vertical axis while its base iterator provides horizontal navigation. More...
struct	binary_operation_obj< Derived, Result >
	A generic binary operation on viewsUse this class as a convenience superclass when defining an operation for any image views. Many operations have different behavior when the two views are compatible. This class checks for compatibility and invokes apply_compatible(V1,V2) or apply_incompatible(V1,V2) of the subclass. You must provide apply_compatible(V1,V2) method in your subclass, but apply_incompatible(V1,V2) is not required and the default throws std::bad_cast. More...
