Im loading a picture search from the web using Pgraphic this is working fine but when i go to search the next picture, it doesn't get rid of the old picture data

So i guess what i am asking, is there a way to clear all the data in my Pgraphic after i have saved?



  String url = pic_search;
  online = loadImage(pic_search, "png");
  rc.beginDraw();
  rc.image(online, 0,0,500,500);
  rc.endDraw();
  rc.save("picture_search.jpg");



thanks again :)
