# binary_operation_obj Struct Template Reference
[STL-like Algorithms]

`#include <algorithm.hpp>`

Inherited by copy_and_convert_pixels_fn, copy_pixels_fn, and equal_pixels_fn.

List of all members.

## Detailed Description

### template<typename Derived, typename Result = void>
struct boost::gil::binary_operation_obj< Derived, Result >

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.

## Public Types

typedef Result | result_type
