修改位图后，如何修改“修改后的”位图等？

Question

假设我捕获了一个名为_originalBitmap的图像

1. 然后我修改通过_originalBitmap将某种类型的Brightness Increase滤镜应用到

   filteredBitmap = _BrightnessIncrease.filterImage(_originalBitmap);

2. 然后，我单击Apply按钮，将filteredBitmap保存到内存位置。

3. 我想再次在“ filteredBitmap上应用“ Brightness Increase ”。 有谁知道我该怎么做?????????

到目前为止的代码-BrightnessIncrease按钮：

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]);
        }
    });

为什么不将过滤后的位图保存在另一个列表中？

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]);
        }
    });
