Description
- Contain functions to compare color by some criteria.
List
-
- Name
- equal
- Declaration
-
template < typename category_name >
bool equal( color::_internal::model< category_name > const& left, color::_internal::model< category_name > const& right );
- Description
- Compare tow color using equality test.
- Example
-
::color::rgb<double> a{ ::color::constant::orange{} };
::color::rgb<double> b{ ::color::constant::lime{} };
std::cout<< ::color::compare::equal( a, b ) << std::endl;
- Name
- different
- Declaration
-
template < typename category_name >
bool different( color::_internal::model< category_name > const& left, color::_internal::model< category_name > const& right );
- Description
- Compare tow color using different test. If at least one componetn is different tha other function will return true.
- Example
-
::color::rgb<double> a{ ::color::constant::orange{} };
::color::rgb<double> b{ ::color::constant::lime{} };
std::cout<< ::color::compare::different( a, b ) << std::endl;
- Name
- less_strict
- Declaration
-
template < typename category_name >
bool less_strict( color::_internal::model< category_name > const& left, color::_internal::model< category_name > const& right );
- Description
- Lexicografical compare by components if left side is strictly less that right.
- Example
-
::color::rgb<double> a{ ::color::constant::orange{} };
::color::rgb<double> b{ ::color::constant::lime{} };
std::cout<< ::color::compare::less_strict( a, b ) << std::endl;
- Name
- great_strict
- Declaration
-
template < typename category_name >
bool great_strict( color::_internal::model< category_name > const& left, color::_internal::model< category_name > const& right );
- Description
- Lexicografical compare by components if left side is strictly great that right.
- Example
-
::color::rgb<double> a{ ::color::constant::orange{} };
::color::rgb<double> b{ ::color::constant::lime{} };
std::cout<< ::color::compare::great_strict( a, b ) << std::endl;
- Name
- less_or_equal
- Declaration
-
template < typename category_name >
bool less_or_equal( color::_internal::model< category_name > const& left, color::_internal::model< category_name > const& right );
- Description
- Lexicografical compare by components if left side is less or equal that right.
- Example
-
::color::rgb<double> a{ ::color::constant::orange{} };
::color::rgb<double> b{ ::color::constant::lime{} };
std::cout<< ::color::compare::less_or_equal( a, b ) << std::endl;
- Name
- great_or_equal
- Declaration
-
template < typename category_name >
bool great_or_equal( color::_internal::model< category_name > const& left, color::_internal::model< category_name > const& right );
- Description
- Lexicografical compare by components if left side is great or equal that right.
- Example
-
::color::rgb<double> a{ ::color::constant::orange{} };
::color::rgb<double> b{ ::color::constant::lime{} };
std::cout<< ::color::compare::great_or_equal( a, b ) << std::endl;
- Name
- darker
- Declaration
-
template < typename category_name >
bool darker( color::_internal::model< category_name > const& left, color::_internal::model< category_name > const& right );
- Description
- Equvalent with
typedef typename ::color::trait::scalar< category_name > ::instance_type scalar_type;
::color::gray< scalar_type > ( left ) < ::color::gray< scalar_type >( right );
- Example
-
::color::rgb<double> a{ ::color::constant::orange{} };
::color::rgb<double> b{ ::color::constant::lime{} };
std::cout<< ::color::compare::darker( a, b ) << std::endl;
- Name
- brighter
- Declaration
-
template < typename category_name >
bool brighter( color::_internal::model< category_name > const& left, color::_internal::model< category_name > const& right );
- Description
- Equvalent with:
typedef typename ::color::trait::scalar< category_name > ::instance_type scalar_type;
::color::gray< scalar_type > ( left ) > ::color::gray< scalar_type >( right );
- Example
-
::color::rgb<double> a{ ::color::constant::orange{} };
::color::rgb<double> b{ ::color::constant::lime{} };
std::cout<< ::color::compare::brighter( a, b ) << std::endl;
