◆ Rect32f() [4/5]

icl::utils::Rect32f::Rect32f ( const Rect32f & r )

inline

create a deep copy of a rect

◆ Rect32f() [5/5]

icl::utils::Rect32f::Rect32f ( const Rect & rect )

inline

create a floating point rect from given int-valued rect

Member Function Documentation

◆ bottom()

inline

returns the position of the bottom border

◆ center()

Point32f icl::utils::Rect32f::center ( ) const
