struct  iterator_add_deref< Iterator, D >
 Returns the type (and creates an instance) of an iterator that invokes the given dereference adaptor upon dereferencing. More...
class  point2< T >
 2D point both axes of which have the same dimension typeModels: Point2DConcept More...
struct  num_channels< T >
 Returns the number of channels of a pixel-based GIL construct. More...
class  pixel_2d_locator_base< Loc, XIterator, YIterator >
 base class for models of PixelLocatorConceptPixel locator is similar to a pixel iterator, but allows for 2D navigation of pixels within an image view. It has a 2D difference_type and supports random access operations like: 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...
