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.

Constructor & Destructor Documentation
| ImageIterator | ( | pointer | base, |
| std::ptrdiff_t | ystride | ||
| ) |
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.
