Detailed Description

template<class IMAGE_ITERATOR>
class vigra::LineIterator< IMAGE_ITERATOR >

Iterator adapter to iterate along an arbitrary line on the image.

This iterator may be initialized from a standard ImageIterator, a MultibandImageIterator and so on. It gives you STL-compatible (forward iterator) access to an arbitrary line on the image. The iterator gets associated with the accessor of the base iterator.

#include <vigra/imageiteratoradapter.hxx>
Namespace: vigra

Examples:

profile.cxx.
