Rotate an object by variable degree value(Clockwise)
By Shaswati Saha
Use below code snippet to rotate an object around its center point by a changeable degree value in clockwise direction.
@param[in] object_to_rotate The object you want to rotate
@param[in] degree The degree you want to rotate
@param[in] cx The rotation's center horizontal position
@param[in] cy The rotation's center vertical position
void view_rotate_object(Evas_Object *object_to_rotate, double degree, Evas_Coord cx, Evas_Coord cy)
{
Evas_Map *m = NULL;
if (object_to_rotate == NULL) {
dlog_print(DLOG_ERROR, LOG_TAG, "object is NULL");
return;
}
m = evas_map_new(4);
evas_map_util_points_populate_from_object(m, object_to_rotate);
evas_map_util_rotate(m, degree, cx, cy);
evas_object_map_set(object_to_rotate, m);
evas_object_map_enable_set(object_to_rotate, EINA_TRUE);
evas_map_free(m);
}
