Methods


void set_obj(lg_object *obj);
Sets the object for this video handler.

virtual int render ();
This function is called by lg_object::render and it's defined as virtual so you may create different rendering methods for different kinds of objects. For instance, you may objects that are animated (sprites) or static (surfaces).

void get_size(int *w, int *h);
This function is called by lg_object::get_size, or by you, to check the size of the object.
