Detailed Description

template<typename TImage>
class itk::ImageRegionRange< TImage >

Modern C++11 range to iterate over the pixels of an image region. Designed to conform to Standard C++ Iterator requirements, so that it can be used in range-based for loop, and passed to Standard C++ algorithms.

The following example adds 42 to each pixel, using a range-based for loop:

ImageRegionRange<ImageType> range{ *image, imageRegion };
 
for (auto&& pixel : range)
{
  pixel = pixel + 42;
}

The following example prints the values of the pixels:

for (const auto pixel : range)
{
  std::cout << pixel << std::endl;
}
