Calculate the intersection of a rectangle and line segment.
const SDL_Rect * SDL_bool SDL_IntersectRectAndLine(int *X1, rect, int *Y1, int *X2, int *Y2);
|rect||an SDL_Rect structure representing the rectangle to intersect|
|X1||a pointer to the starting X-coordinate of the line|
|Y1||a pointer to the starting Y-coordinate of the line|
|X2||a pointer to the ending X-coordinate of the line|
|Y2||a pointer to the ending Y-coordinate of the line|
Returns SDL_TRUE if there is an intersection, SDL_FALSE otherwise.
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
Y2 as necessary.
This function is available since SDL 2.0.0.
