Classes

struct  binary_operation_obj
 A generic binary operation on views

Use this class as a convenience superclass when defining an operation for any image views. Many operations have different behavior when the two views are compatible. This class checks for compatibility and invokes apply_compatible(V1,V2) or apply_incompatible(V1,V2) of the subclass. You must provide apply_compatible(V1,V2) method in your subclass, but apply_incompatible(V1,V2) is not required and the default throws std::bad_cast. More...
