Member Function Documentation

void SURectf::Normalize

(

)

[inline]

Arranges the rectangle to ensure x1 <= x2 and y1 <= y2.

double SURectf::Width

(

)

const [inline]

Returns the width of this rectangle.

Returns:

The width of this rectangle which might be negative if not normalized.

double SURectf::Height

(

)

const [inline]

Returns the height of this rectangle.

Returns:

The height of this rectangle which might be negative if not normalized.

void SURectf::Inflate

(

const SUSizef &

s

)

[inline]

Increases the size of the rectangle with two times s (each side once).

Postcondition:

The rectangle is normalized.

bool SURectf::Contains

(

const SUPointf &

p

)

[inline]

Returns true if the point p is contained within the rectangle, otherwise false.

bool SURectf::Contains	(	double	x,
		double	y
	)			const [inline]

Returns true if the point at coordinate (x, y) is contained within the rectangle, otherwise false.

bool SURectf::Intersects

(

const SURectf &

r

)

const [inline]

Returns true if the rectangle intersects the rectangle r, otherwise false.
