Function Documentation

operator==()

template< typename T > bool operator==	(	const Rectangle< T > &	r1,
		const Rectangle< T > &	r2
	)

Compares two rectangles by all four sides.

left, top, right and bottom are compared independently. Two rectangles of equal width and height compare equal only when they also share the same origin.

Parameters

[in]	r1	- a first rectangle.
[in]	r2	- a second rectangle.

Returns

true when all four sides are equal.

operator!=()

template< typename T > bool operator!=	(	const Rectangle< T > &	r1,
		const Rectangle< T > &	r2
	)

Compares two rectangles by any differing side.

The result is true when left, top, right or bottom differs.

Parameters

[in]	r1	- a first rectangle.
[in]	r2	- a second rectangle.

Returns

true when any side differs.

operator/()

template< class T1, class T2 > Rectangle< T1 > operator/	(	const Rectangle< T1 > &	rect,
		const T2 &	value
	)

Divides every side by a scalar.

The result is Rectangle<T1>(left / value, top / value, right / value, bottom / value). Construction converts each quotient back to T1, so Rectangle<ptrdiff_t> divided by a floating value is rounded to the nearest integer. Integer division truncates toward zero. TestResize builds the chroma rectangle as the luma rectangle / 2.

Parameters

[in]	rect	- a rectangle.
[in]	value	- a non-zero scalar.

Returns

the rectangle with divided sides.

operator*() [1/2]

template< class T1, class T2 > Rectangle< T1 > operator*	(	const Rectangle< T1 > &	rect,
		const T2 &	value
	)

Multiplies every side by a scalar.

The result is Rectangle<T1>(left * value, top * value, right * value, bottom * value). A floating factor applied to Rectangle<ptrdiff_t> is rounded by the constructor. Motion debug drawing paints object.rect * scale on the full-resolution frame.

Parameters

[in]	rect	- a rectangle.
[in]	value	- a scalar factor.

Returns

the rectangle with multiplied sides.

operator*() [2/2]

template< class T1, class T2 > Rectangle< T1 > operator*	(	const T2 &	value,
		const Rectangle< T1 > &	rect
	)

Multiplies a scalar by every side of a rectangle.

The result is the same as rect * value. A floating factor applied to Rectangle<ptrdiff_t> is rounded by the constructor.

Parameters

[in]	value	- a scalar factor.
[in]	rect	- a rectangle.

Returns

the rectangle with multiplied sides.

operator+()

template< typename T > Rectangle< T > operator+	(	const Rectangle< T > &	r1,
		const Rectangle< T > &	r2
	)

Adds the corresponding sides of two rectangles.

The result is (r1.left + r2.left, r1.top + r2.top, r1.right + r2.right, r1.bottom + r2.bottom). This is the same sum as operator +=. The bounding union is operator |=. Motion accumulates this sum and then divides by the number of rectangles to average a box.

Parameters

[in]	r1	- a first rectangle.
[in]	r2	- a second rectangle.

Returns

the rectangle with summed sides.
