## Detailed Description

### template<class PIXELTYPE>
class vigra::ImageIterator< PIXELTYPE >

Standard 2D random access iterator for images that store the data in a linear array.

Most functions and local types are inherited from ImageIteratorBase.

See the paper: U. Koethe: Reusable Algorithms in Image Processing for a discussion of the concepts behind ImageIterators.

## Member Typedef Documentation

typedef Base::difference_type difference_type

| the iterator's difference type (argument type of `iter[diff]`) Reimplemented from ImageIteratorBase< ImageIterator< PIXELTYPE >, PIXELTYPE, PIXELTYPE &, PIXELTYPE * >.

typedef Base::pointer pointer

| the iterator's pointer type (return type of `iter.operator->()`) Reimplemented from ImageIteratorBase< ImageIterator< PIXELTYPE >, PIXELTYPE, PIXELTYPE &, PIXELTYPE * >.

## Constructor & Destructor Documentation

ImageIterator | ( | pointer | base,
|  | int | ystride
| ) | `[inline]`

| Construct from raw memory with a vertical stride of `ystride`. `ystride` must equal the physical image width (row length), even if the iterator will only be used for a sub image. If the raw memory is encapsulated in an image object this object should have a factory function that constructs the iterator.
