Function sdl2_sys::SDL_IntersectRectAndLine

pub unsafe extern "C" fn SDL_IntersectRectAndLine(
    rect: *const SDL_Rect,
    X1: *mut c_int,
    Y1: *mut c_int,
    X2: *mut c_int,
    Y2: *mut c_int
) -> SDL_bool

Calculate the intersection of a rectangle and line segment.

This function is used to clip a line segment to a rectangle. A line segment contained entirely within the rectangle or that does not intersect will remain unchanged. A line segment that crosses the rectangle at either or both ends will be clipped to the boundary of the rectangle and the new coordinates saved in X1, Y1, X2, and/or Y2 as necessary.

\param rect an SDL_Rect structure representing the rectangle to intersect \param X1 a pointer to the starting X-coordinate of the line \param Y1 a pointer to the starting Y-coordinate of the line \param X2 a pointer to the ending X-coordinate of the line \param Y2 a pointer to the ending Y-coordinate of the line \returns SDL_TRUE if there is an intersection, SDL_FALSE otherwise.

\since This function is available since SDL 2.0.0.
