修改位圖后，如何修改“修改后的”位圖等？

Question

假設我捕獲了一個名為_originalBitmap的圖像

1. 然后我修改通過_originalBitmap將某種類型的Brightness Increase濾鏡應用到

   filteredBitmap = _BrightnessIncrease.filterImage(_originalBitmap);

2. 然后，我單擊Apply按鈕，將filteredBitmap保存到內存位置。

3. 我想再次在“ filteredBitmap上應用“ Brightness Increase ”。 有誰知道我該怎么做?????????

到目前為止的代碼-BrightnessIncrease按鈕：

Button filter6Button = (Button) findViewById(R.id.filter6_button);
    filter6Button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {


            for (int i = MainActivity.LEFT_IMAGE; i <= MainActivity.RIGHT_IMAGE; i++) {

                _filteredBitmaps[i] = _BrightnessIncrease
                        .filterImage(_originalBitmaps[i]);
                // */
            }
            _filterImageView
                    .setImageBitmap(_filteredBitmaps[MainActivity.LEFT_IMAGE]);
        }
    });

為什么不將過濾后的位圖保存在另一個列表中？

for (int i = MainActivity.LEFT_IMAGE; i <= MainActivity.RIGHT_IMAGE; i++) {
    _filterImageView[i] = _originalBitmaps[i].copy(_originalBitmaps[i].getConfig(), true);
} 
    Button filter6Button = (Button) findViewById(R.id.filter6_button);
    filter6Button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {


            for (int i = MainActivity.LEFT_IMAGE; i <= MainActivity.RIGHT_IMAGE; i++) {

                _filterImageView[i] = _BrightnessIncrease
                        .filterImage(_filterImageView[i]);
                // */
            }
            _filterImageView
                    .setImageBitmap(_filterImageView[MainActivity.LEFT_IMAGE]);
        }
    });
