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

the iterator's pointer type (return type of iter.operator->())

Reimplemented from ImageIteratorBase< ImageIterator< PIXELTYPE >, PIXELTYPE, PIXELTYPE &, PIXELTYPE * >.

the iterator's difference type (argument type of iter[diff])

Reimplemented from ImageIteratorBase< ImageIterator< PIXELTYPE >, PIXELTYPE, PIXELTYPE &, PIXELTYPE * >.


Constructor & Destructor Documentation

ImageIterator ( pointer  base,
int  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.
