## Classes
class | pixel_2d_locator_base
| base class for models of PixelLocatorConcept Pixel 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
| Memory-based pixel locator. Models: PixelLocatorConcept,HasDynamicXStepTypeConcept,HasDynamicYStepTypeConcept,HasTransposedTypeConcept The 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...
