private void settingbitmaptodraw() {     // todo auto-generated method stub      resultbitmap=bitmap.createscaledbitmap(resultbitmap, width, height, true);     matrix matrix=new matrix();     matrix.setrotate(to_degree);     tempbitmap=bitmap.createbitmap                             (resultbitmap, 0, 0, width, height, matrix, true);     if(bitmap!=null)     {         bitmap.recycle();         bitmap=null;     }        bitmap=bitmap.createbitmap(width, height, tempbitmap.getconfig());     canvas=new canvas(bitmap);     invalidate();  }
