Gets the area of the rectangle.

Since:
3.0, DALi version 1.0.0
Returns:
The area of the rectangle
template<typename T = float>
T Dali::Rect< T >::Bottom ( ) const

Gets the bottom of the rectangle.

Since:
3.0, DALi version 1.0.0
Returns:
The bottom of the rectangle
template<typename T = float>
bool Dali::Rect< T >::Contains ( const Rect< T > &  other) const

Determines whether or not this Rectangle contains the specified rectangle.

Since:
3.0, DALi version 1.0.0
Parameters:
