# Models
[Pixel Iterator]

## Detailed Description

Pixel iterator models.

## Modules

| bit_aligned_pixel_iterator
| An iterator over non-byte-aligned pixels. Models PixelIteratorConcept, PixelBasedConcept, MemoryBasedIteratorConcept, HasDynamicXStepTypeConcept.

| iterator_from_2d
| An iterator over two-dimensional locator. Useful for iterating over the pixels of an image view. Models PixelIteratorConcept, PixelBasedConcept, HasDynamicXStepTypeConcept.

| Pointer to packed_pixel<P,CR,Layout>
| Iterators over interleaved pixels. The pointer packed_pixel<P,CR,Layout>* is used as an iterator over interleaved pixels of packed format. Models PixelIteratorConcept, HasDynamicXStepTypeConcept, MemoryBasedIteratorConcept.

| C pointer to a pixel
| Iterators over interleaved pixels. A C pointer to a model of PixelValueConcept is used as an iterator over interleaved pixels. Models PixelIteratorConcept, HomogeneousPixelBasedConcept, HasDynamicXStepTypeConcept, MemoryBasedIteratorConcept.

| dereference_iterator_adaptor
| An iterator that invokes a provided function object upon dereference. Models: IteratorAdaptorConcept, PixelIteratorConcept.

| planar_pixel_iterator
| An iterator over planar pixels. Models PixelIteratorConcept, HomogeneousPixelBasedConcept, MemoryBasedIteratorConcept, HasDynamicXStepTypeConcept.

| position_iterator
| An iterator that remembers its current X,Y position and invokes a function object with it upon dereferencing. Models PixelIteratorConcept, PixelBasedConcept, HasDynamicXStepTypeConcept. Used to create virtual image views.

| step iterators
| Iterators that allow for specifying the step between two adjacent values.
