template<class R1, class R2> class pair_raster_view;

The pair_raster_view class presents a form of zip-iteration for two same-sized rasters, each comforming to the RasterView concept. The value_type of the tuple_raster_view is a std::pair of the value_type’s of the two rasters. The reference type is a std::pair of the reference types of the two rasters.

Both R1 and R2 are required to conform to the RasterView concept. The pair_raster_view is Subbable if R1 and R2 are Subbable. The pair_raster_view is RecursivelySubbable if all of R1 and R2 are RecursivelySubbable.

The iterator and const_iterator types associated with the pair_raster_view class are conforming to the RasterIterator and RandomAccessible concepts.

The pair_raster_view has the following public interface (along with default constructors, and assignment operators).

   pair_raster_view(const R1& r1, const R2& r2);

The following member functions implement the RasterView and Subbable concepts.

iterator begin(); 
iterator end(); 
const_iterator begin() const;
const_iterator end() const;
int rows() const;
int cols() const;
int size() const;
   
pair_raster_view::sub_raster_type sub_raster(int start_row, int start_col, int rows, int cols);
