Function Documentation

◆ SDL_EnclosePoints()

DECLSPEC SDL_bool SDLCALL SDL_EnclosePoints	(	const SDL_Point *	points,
		int	count,
		const SDL_Rect *	clip,
		SDL_Rect *	result
	)

Calculate a minimal rectangle enclosing a set of points.

Returns: SDL_TRUE if any points were within the clipping rect

◆ SDL_HasIntersection()

DECLSPEC SDL_bool SDLCALL SDL_HasIntersection	(	const SDL_Rect *	A,
		const SDL_Rect *	B
	)

Determine whether two rectangles intersect.

Returns: SDL_TRUE if there is an intersection, SDL_FALSE otherwise.

◆ SDL_IntersectRect()

DECLSPEC SDL_bool SDLCALL SDL_IntersectRect	(	const SDL_Rect *	A,
		const SDL_Rect *	B,
		SDL_Rect *	result
	)

Calculate the intersection of two rectangles.

Returns: SDL_TRUE if there is an intersection, SDL_FALSE otherwise.

◆ SDL_IntersectRectAndLine()

DECLSPEC SDL_bool SDLCALL SDL_IntersectRectAndLine	(	const SDL_Rect *	rect,
		int *	X1,
		int *	Y1,
		int *	X2,
		int *	Y2
	)

Calculate the intersection of a rectangle and line segment.

Returns: SDL_TRUE if there is an intersection, SDL_FALSE otherwise.
