          if (result.success()) {
            // Note: in most cases, we will return data all in one asset,
            // except that we return multiple assets for multi-page
images.
            for (Asset asset1 : result.getOutputDoc().getAssets()) {
              doSomethingWithAsset(asset1.getData());
            }
