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.


ImageIterator   [inline]
