Detailed Description

template<typename T>
struct ev::Circ_< T >

This class defines a circle given its center and radius.

Analogously to OpenCV library, the following aliases are defined for convenience:

using Circi = Circ_<int>;
using Circl = Circ_<long>;
using Circf = Circ_<float>;
using Circd = Circ_<double>;
using Circ = Circi;

Member Function Documentation

contains()

template<typename T>

template<typename Te>

bool ev::Circ_< T >::contains ( const Event_< Te > & e ) const

inlinenodiscard

Check if the circle contains an event.

Parameters

e	Event to check

Returns

True if the event is inside

Warning

This function assumes that the boundary of the circle is inclusive.

empty()

template<typename T>

bool ev::Circ_< T >::empty ( ) const

inlinenodiscard

Check if empty.

Returns

True if empty
