Calculate a minimal rectangle enclosing a set of points.


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

Function Parameters

points an array of SDL_Point structures representing points to be enclosed
count the number of structures in the points array
clip an SDL_Rect used for clipping or NULL to enclose all points
result an SDL_Rect structure filled in with the minimal enclosing rectangle

Return Value

Returns SDL_TRUE if any points were enclosed or SDL_FALSE if all the points were outside of the clipping rectangle.


If clip is not NULL then only points inside of the clipping rectangle are considered.


This function is available since SDL 2.0.0.
