    } 
 
    // 指定大小載入圖片 
    public static Bitmap getBitmap(String path, int size) {

    // 按寬高壓縮載入圖片 
    public static Bitmap getBitmap(String path, int width, int heigh) { 
        Options op = new Options(); 
        op.inJustDecodeBounds = true; 
        Bitmap bt = BitmapFactory.decodeFile(path, op); 
        int xScale = op.outWidth / width; 
        int yScale = op.outHeight / heigh; 
        op.inSampleSize = xScale > yScale ? xScale : yScale; 
        op.inJustDecodeBounds = false; 
        bt = BitmapFactory.decodeFile(path, op); 
        return bt;
