A multi-dimensional iterator templated over image type that walks a region of pixels.
The itk::ImageRegionIterator is optimized for iteration speed and is the first choice for iterative, pixel-wise operations on an image. ImageRegionIterator is the least specialized of the ITK image iterator classes. ImageRegionIterator is templated over the image type, and is constrained to walk only within the specified region and along a line parallel to one of the coordinate axes, "wrapping" to the next line as it reaches the boundary of the image. To walk the entire image, specify the region to be image->GetRequestedRegion()
.
Most of the functionality is inherited from the ImageRegionConstIterator. The current class only adds write access to image pixels.

typedef Superclass::PixelContainer itk::ImageRegionIterator< TImage >::PixelContainer |
PixelContainer typedef support. Used to refer to the container for the pixel data. While this was already typdef'ed in the superclass it needs to be redone here for this subclass to compile properly with gcc.

itk::ImageRegionIterator< TImage >::ImageRegionIterator | ( | ) |
Default constructor. Needed since we provide a cast constructor.
itk::ImageRegionIterator< TImage >::ImageRegionIterator | ( | ImageType * | ptr, |
const RegionType & | region | ||
) |
Constructor establishes an iterator to walk a particular image and a particular region of that image.
itk::ImageRegionIterator< TImage >::ImageRegionIterator | ( | const ImageIterator< TImage > & | it | ) |
Constructor that can be used to cast from an ImageIterator to an ImageRegionIterator. Many routines return an ImageIterator but for a particular task, you may want an ImageRegionIterator. Rather than provide overloaded APIs that return different types of Iterators, itk returns ImageIterators and uses constructors to cast from an ImageIterator to a ImageRegionIterator.
itk::ImageRegionIterator< TImage >::ImageRegionIterator | ( | const ImageRegionConstIterator< TImage > & | it | ) | [protected] |
the construction from a const iterator is declared protected in order to enforce const correctness.
Self itk::ImageRegionIterator< TImage >::Begin | ( | void | ) | const |
Return an iterator for the beginning of the region. "Begin" is defined as the first pixel in the region.
Reimplemented from itk::ImageRegionConstIterator< TImage >.
Self itk::ImageRegionIterator< TImage >::End | ( | void | ) | const |
Return an iterator for the end of the region. "End" is defined as one pixel past the last pixel of the region.
Reimplemented from itk::ImageRegionConstIterator< TImage >.
Self& itk::ImageRegionIterator< TImage >::operator= | ( | const ImageRegionConstIterator< TImage > & | it | ) | [protected] |
the construction from a const iterator is declared protected in order to enforce const correctness.
void itk::ImageRegionIterator< TImage >::Set | ( | const PixelType & | value | ) | const [inline] |
Set the pixel value
Definition at line 113 of file itkImageRegionIterator.h.
PixelType& itk::ImageRegionIterator< TImage >::Value | ( | void | ) | [inline] |
Return a reference to the pixel This method will provide the fastest access to pixel data, but it will NOT support ImageAdaptors.
