This can be used to facilitate further detection, e.g., by zooming in the camera to get a clearer image of any barcode in the returned bounding box. #### public [BarcodeScannerOptions.Builder](https://developers.google.com/android/reference/com/google/mlkit/vision/barcode/BarcodeScannerOptions.Builder) **setBarcodeFormats** (int format, int... moreFormats) Sets the interested barcode formats defined in `https://developers.google.com/android/reference/com/google/mlkit/vision/barcode/common/Barcode.BarcodeFormat`. e.g. `setBarcodeFormats(Barcode.FORMAT_QR_CODE, Barcode.FORMAT_UPC_A)`. Reducing the number of supported formats will make the barcode scanner faster. Only the last call will be respected if calling this method multiple times Default: all formats are supported. ##### Parameters | format | supported barcode format | | moreFormats | more supported barcode formats | |---|---| #### public [BarcodeScannerOptions.Builder](https://developers.google.com/android/reference/com/google/mlkit/vision/barcode/BarcodeScannerOptions.Builder) **setExecutor** ([Executor](https://developer.android.com/reference/java/util/concurrent/Executor.html) executor) Sets the custom `https://developer.android.com/reference/java/util/concurrent/Executor.html` to use. If no `https://developer.android.com/reference/java/util/concurrent/Executor.html` is set, an internal background thread pool will be used. Most clients should not need to call this method. ##### Parameters | executor | the `https://developer.android.com/reference/java/util/concurrent/Executor.html` to use | |---|---| ##### Returns - this object, for chaining method calls #### public [BarcodeScannerOptions.Builder](https://developers.google.com/android/reference/com/google/mlkit/vision/barcode/BarcodeScannerOptions.Builder) **setZoomSuggestionOptions** ([ZoomSuggestionOptions](https://developers.google.com/android/reference/com/google/mlkit/vision/barcode/ZoomSuggestionOptions) zoomSuggestionOptions) Sets the `https://developers.google.com/android/reference/com/google/mlkit/vision/barcode/ZoomSuggestionOptions` to use. If this is specified, then the library will suggest zooming the camera if the barcode is too far away or too small to be detected. ##### Parameters | zoomSuggestionOptions | the `https://developers.google.com/android/reference/com/google/mlkit/vision/barcode/ZoomSuggestionOptions` to use | |---|---| ##### Returns - this object, for chaining method calls.
