Changelog | Android Document Scanner

Version 5.0.1 (13 Mar 2024)

🐞 Bug fixes:
- Fixed a bug in the Generic Document Scanner which prevented the extraction of the given names as well as the valid from date from a residence permit card.

Version 5.0.0 (1 Mar 2024)

🎉 New:
- Added new freshly designed RTU-UI version 2 for Barcode scanning with advanced agile configuration. Use io.scanbot:rtu-ui-v2-bundle module dependency to access the new screen.
- Added new ParametricFilters in ImageProcessor API (ScanbotBinarizationFilter, CustomBinarizationFilter, ColorDocumentFilter, BrightnessFilter, ContrastFilter, GrayscaleFilter, WhiteBlackPointFilter and LegacyFilter).
- Added support for German residence permits (2011 and 2019 formats) in GenericDocumentRecognizer.
- PdfConfig in the PDFWriter now allows setting the jpegQuality for images encoding. The parameter is only used when transcoding images (adding an image from a bitmap, or resample is true). The parameter is ignored when directly embedding JPEG files.
- Added resample parameter in PdfConfig and extended the meaning of the dpi setting.
- Added new constructor parameters dpi: Int and pageFit: PageFit in PageConfig class for PDFWriter.
- Added setParametricFilter(parametricFilter: ParametricFilter) method in DocumentScannerConfiguration for DocumentScanner RTU UI screen.
- Added support of minEstimatedNumberOfSymbolsForNoDocument config parameter in DocumentQualityAnalyzer API.
🚀 Improvements:
- Optimized speed of the camera preview frames handling for all scanners.
- Optimized memory consumption for PDF rendering with encryption enabled.
- Text detection is faster and more accurate.
- Improved MRZ parser for a stronger rejection of outliers.
- Improved speed and quality of scanning for GenericDocumentRecognizer.
- Changed touch to focus square in ScanbotCameraXView to a circle.
🐞 Bug fixes:
- For BarcodeFormat.PDF_417, a single case to generate clusters was not covered, which led to a crash.
- Fixed potential crash when trying to embed invalid images in a PDF.
- Fixed issue with misaligned document polygon and barcode polygons on some devices with horizontal orientation.
- Fixed drawing of the detected document contour polygon in landscape orientation.
- Fixed NPE in MRZ scanning with optional fields.
⚠️ Breaking changes:
- Changes in ImageProcessor API:
  - ImageProcessor is not a singleton anymore.
  - Removed scanbotSDK.imageProcessor() getter. Call one of ImageProcessor constructors to create a new instance.
  - Removed old process*(List<Operation>) methods and Operation classes. They are replaced with applyFilter(), rotate(), crop(), resize() methods in ImageProcessor. Call ImageProcessor#processedBitmap(), ImageProcessor#encodedProcessedImage(), or ImageProcessor#saveProcessedImage(path: String) to get the image result or to write it to a file.
  - ImageFilterType enum is deprecated. Use ParametricFilter API with new filters. Usage of old filters is still available with LegacyFilter wrapper.
  - ImageFilterTuneTypes are no longer supported. The class was deleted.
- Changes in PageProcessor API:
  - PageProcessor methods are also migrated to the ParametricFilter API.
  - Added parametricFilters: List<ParametricFilter> field in Page class. It will be used in page processing by default. If it's empty, old legacy filter in filter: ImageFilterType deprecated field will be used.
  - Removed tunes and filterOrder fields in Page class.
- Deprecated setImageFilterType(imageFilterType: ImageFilterType) method in DocumentScannerConfiguration for the DocumentScanner RTU UI screen.
- Removed imageProcessorType(type: ImageProcessor.Type) in ScanbotSDKInitializer.
- In TIFFImageWriterParameters constructor replaced binarizationFilter: ImageFilterType? parameter with binarizationFilter: ParametricFilter?.
- In TIFFImageWriterParameters.defaultParametersForBinaryImages() parameters changed the default filter to ScanbotBinarizationFilter parametric filter.
- Renamed RSS_14 barcode format to DATABAR and RSS_EXPANDED to DATABAR_EXPANDED.
- BatchBarcodeScannerActivity class from RTU UI v1 is now marked as 'Deprecated'.
- Removed BarcodeFormat.CODE_25 from BarcodeFormat.COMMON_CODES list.
- ZoomRange can be created with any input values but will be limited under the hood by internal MIN_ZOOM (x0.2) and MAX_ZOOM (x100) values.
🚙 Under the hood:
- Added 3rd-party library "libzueci" to dependencies.
- Class SoundController was renamed to SoundControllerImpl and interface SoundController was extracted.

Version 4.2.0 (9 Jan 2024)

🎉 New:
- Added support for new barcode type BarcodeFormat.GS1_COMPOSITE.
- Added analyzer image size limit property for Document Quality Analyzer. By default, the image will be resized to 2500 px.
- Added support for the Israelian Check standard.
🚀 Improvements:
- Added more control over how to handle GS1 messages in barcodes. See BarcodeScannerAdditionalConfig.setGs1HandlingMode.
🐞 Bug fixes:
- Fixed the Camera Preview blinking after capturing a picture.
⚠️ Breaking Changes:
- The property enableGS1Decoding has been replaced by the enum Gs1HandlingMode in BarcodeScannerAdditionalConfig.
- GS1 codes are now handled differently for various barcode types. Using the default option PARSE will give the same result as before for all barcode types, except of RSS_EXPANDED. Previously, for RSS_EXPANDED, the result was inconsistently returned with parentheses. Now, to get results with parentheses for all barcode types, it is needed to choose the option DECODE.

Version 4.1.1 (1 Dec 2023)

🎉 New:
- Added support for Kuwait ID cards in the MRZ scanner.
🐞 Bug fixes:
- Fixed an issue with acceptedSizeScore config parameter for DocumentScannerActivity and FinderDocumentScannerActivity RTU screens.
⚠️ Breaking changes:
- Moved setIgnoreBadAspectRatio() logic from DocumentAutoSnappingController to ContourDetectorFrameHandler.

Version 4.1.0 (23 Nov 2023)

🎉 New:
- Added new feature - Document Quality Analyzer. It analyzes the text quality (legibility) on images.
- Added new supported barcode formats - BarcodeFormat.USPS_INTELLIGENT_MAIL, BarcodeFormat.ROYAL_MAIL, BarcodeFormat.JAPAN_POST, BarcodeFormat.ROYAL_TNT_POST, BarcodeFormat.AUSTRALIA_POST and DATABAR_LIMITED.
🚀 Improvements:
- Improved quality and speed of the Document Contour detector.
- Decreased size of Document Contour detector ML model.
- Removed parameter forceCpu: Boolean from ImageProcessor methods.
- Optimized default and custom preview/picture size selection in the ScanbotCameraXView.
- Optimized setForceMaxSnappingSize(enabled: Boolean) behavior in the ScanbotCameraXView.
- Improved pinch-to-zoom gesture in ScanbotCameraXView.
- Added setLifecycleOwner(lifecycleOwner: LifecycleOwner) method for view controller in DocumentScannerView and BarcodeScannerView to improve compatibility with Compose UI.
🐞 Bug fixes:
- Added setBarcodeFormatsFilter(barcodeFormat: List<BarcodeFormat>) method in BatchBarcodeScannerConfiguration class.
⚠️ Breaking changes:
- Renamed OpticalCharacterRecognizer.EngineMode.TLDR to OpticalCharacterRecognizer.EngineMode.SCANBOT_OCR.
- If you are using setPictureSize(pictureSize: Size), setCameraFrameSize(frameSize: Size) or setPreviewFrameSize(frameSize: Size), make sure input Size has the correct orientation (fits the view or display size).
- All scanner components have been switched to zoom ratio (values 1x, 2x, etc.) instead of linear zoom (from 0 to 1). Methods renamed: setOpticalZoomRange() -> setPhysicalZoomRange(); setOpticalZoomLevel() -> setPhysicalZoomRatio() in ScanbotCameraXView, DocumentScannerView, BarcodeScanAndCountView and BarcodeScannerView. setPhysicalZoomRange() and setPhysicalZoomRatio() accept possible zoom values from 0.5x up to 100x. NOTE: if the value sent to the camera is out of range for a specific device's capabilities, then the camera will try to set the max or min possible for that specific device. eg. Zoom 100x will only work on some high-end Samsung devices, whereas other devices will only have 12x-30x max. The same goes for minimum supported values, 0.5x is a wide-format camera module that does not exist on many Android devices.
- IMPORTANT! Removed deprecated BlurEstimator feature. Use DocumentQualityAnalyzer instead.
🚙 Under the hood:
- Updated version of Nameof C++ library to v0.10.3.
- Disabled GPU acceleration for Redmi 9 models, Samsung Galaxy Grand Prime and devices with Android older than 6.

- Fixed colors not being applied to fields in RTU UI of Generic Document recognizer.
- Fixed bug for BarcodePolygonsStaticView where it crashed if barcodeItemViewFactory returned null instead of view.
- Before, for certain invalid decodings of QR and MicroQR codes, an exception was thrown from ZXing. Now we rigorously treat this as a format error.
- Before, we have returned CODE_25 results when INDUSTRIAL_2_OF_5 was enabled and CODE_25 was disabled. Now, we do not return the CODE_25 result for such decoding options.
- Fixed the topBarButtonsColor option for the MrzScannerActivity and HealthInsuranceCardScannerActivity screens.
- Potential fix for rare crash in ScanbotCameraXView during binding it to lifecycle.
⚠️ Breaking changes:
- Text Data Scanner no longer requires Tesseract OCR blobs.
- Text Data Scanner (both RTU UI component and classic) no longer accepts TextFilterStrategy and a set of Language parameters. The code that sets these needs no replacement and can be removed.
- Changed the structure of MRZGenericDocument. Now it contains a document object for MRZ fields, the same as GenericDocument from GenericDocumentRecogniser. Use MRZGenericDocument.document.wrap() as MRZ to get exact fields instead of a list of generic fields.
- Removed methods from BarcodePolygonsView and BarcodeScannerView.selectionOverlayController related to polygon and text view appearance. E.g. setStrokeColor etc. Please use BarcodeAppearanceDelegate instead!

  - Removed fields: List<MRZField> list and MRZField class. All detected fields are now stored in the document: GenericDocument field in MRZGenericDocument instance as fields: List<Field> list.
  - Added mrzGenericDocument.document.wrap() utility method, which returns a structured object (io.scanbot.genericdocument.entity.MRZ) with MRZ-specific fields for easier access to the detected fields.
  - Removed validCheckDigitsCount: Int, checkDigitsCount: Int, rawMrz: String, and checkDigits: List<MRZCheckDigit> from the resulting model. All this data can be extracted from the GenericDocument.
  - The travelDocType: MRZDocumentType is now represented by the documentType: MRZDocumentType field in the MRZGenericDocument instance.

- Improved cross-platform parameter handling from the refactored configurations structure.
- Added an OPTIONAL 3rd-party open-source dependency: the Pdfium library (licensed under the Apache License Version 2.0). By default, the Pdfium library is NOT added to the Scanbot SDK dependencies.

Version 2.2.0 (27 Apr 2023)

🎉 New:
- Added type BarcodeFormat.CODE_25 that was previously considered as type INDUSTRIAL_2OF5 without checksum. The INDUSTRIAL_2OF5 checksum option is now removed and thus, depending on a valid checksum, we either return INDUSTRIAL_2OF5 or CODE_25.
- Added new field settings in DocumentScannerActivity.Result. It contains the state of the screen options (e.g. autoSnapping, flashEnabled, etc). Since this class implements Parcelable, its instance can be saved and restored for the next scanning session.
- A new machine-learning based machine-readable zone recognizer has been introduced.
- Portuguese ID cards (old and new format) can now be recognized by the MRZ scanners.
🚀 Improvements:
- Added BarcodeItemViewPositionHandler that helps to adjust the position of the barcode description view in relation to the polygon contour.

  - MedicalCertificateInfoBox.patientInfoFields property now available as MedicalCertificateInfoBox.patientInfoBox.patientInfoFields.
  - DateRecord.validationConfidenceValue removed.
- Removed method ScanbotSDKInitializer.prepareMRZBlobs(). MRZ blobs must now be added as a separate module dependency in Gradle: implementation("io.scanbot:sdk-mrz-assets:<SDK_VERSION>").
- Removed MRZRecognitionResult.recognizedMRZLines as it was replaced with MRZRecognitionResult.rawMrz.
- Removed parameter decodeStacks1D. The decoding of stacked barcodes is now handled automatically.
- FrameHandler interface was converted to an abstract class. If you have custom FrameHandlers, please add constructor invocation to your FrameHandler implementation.
- Some of the Scanbot SDK artifact IDs have been changed and need to be updated in your build.gradle's dependencies block:
  - for users of io.scanbot:sdk-package-1, -2, -3 or -4 that use barcode scanning, the dependency of io.scanbot:sdk-barcode-assets should be updated to io.scanbot:bundle-sdk-barcode-assets (NOTE: barcode standalone SDK users do not need to adjust anything in this case: io.scanbot:scanbot-barcode-scanner-sdk and -sdk-ui dependencies are to stay as is!)
  - all users of io.scanbot:sdk-crypto-persistence should change this dependency to io.scanbot:bundle-sdk-crypto-persistence (or to io.scanbot:barcode-sdk-crypto-persistence if you are using Scanbot Barcode standalone SDK)
🚙 Under the hood:
- Enabled -fstack-protector-all on Android
- Removed usage of backward-cpp library.
- Removed outdated assets for MRZ detection.
- FrameHandlers won't return the result if FrameHandler.isEnabled is set to false after actual frame detection.
- We now append the bundle- or barcode- prefix to almost all of our SDK dependencies' names. The modules that have not been changed are those used by customers: rtu-ui-bundle, scanbot-barcode-scanner-sdk, scanbot-barcode-scanner-sdk-ui, io.scanbot:sdk-package-1, -2, -3 and -4 modules, all *-assets modules. The exception to this are modules scanbot-barcode-assets and scanbot-sdk-crypto-persistence: these will have corresponding prefixes from now on, depending on what SDK they are being used for.

Version 2.1.0 (5 Apr 2023)

🎉 New:
- Added method setRequiredAspectRatios() to the DocumentScannerConfiguration that allows you to specify the aspect ratios of the documents that will be automatically captured.
🚀 Improvements:
- Fixed a bug for RTU-UI screens, when using JSON configuration with iOS string formatting patterns.
- Improved performance and accuracy of machine-readable-zone recognition.
- Improved FinderOverlayView behavior, when UI container is dynamically resized, e.g. on keyboard events, etc.
- Added setForceMaxSnappingQuality(enabled: Boolean) in IScanbotCameraView interface (implemented only on ScanbotCameraXView implementation): controls whether the camera should force the maximum possible quality of the snapped picture. As a result, the snapping speed could be significantly slower and the resulting image could be bigger. The default is false.
- Added setSnappingAutoAdjustment(enabled: Boolean) in IScanbotCameraView (implemented only on ScanbotCameraXView implementation): controls whether the camera should apply the final image post-processing (e.g., switching to a low-light mode or HDR, applying face retouch, etc.). Implementation of post-processing depends on the vendor's implementation of Camera API. The default is false.
🐞 Bug fixes:
- Fixed EditPolygonImageView bug with the coloring of lines on the polygon change.

⚠️ Breaking changes:
- Changed the default Camera View to ScanbotCameraXView based on CameraX API in all RTU UI screens
- Removed EngineMode.Legacy support for Barcode Scanner
- ContourDetector's detect methods are now synchronized and return a new DetectionResult entity. It incorporates all data related to contour recognition. Fields that were previously used to obtain this data have been deleted (polygon, polygonF, detectionScore, verticalLines, horizontalLines)
- DetectionResult class name changed to DetectionStatus
- setFinderOffset deleted. Use finderInset values instead
🚙 Under the hood:
- Updated compileSdk version to 31

  - Added returnImageOnSuccess: Boolean parameter for recognize(...) and recognizeWithFinderOverlay(...) methods in CheckRecognizer. By default - false.
- With the new BarcodeScannerView and DocumentScannerView Classical components, the integration of barcode scanning and document scanning with Custom UIs is now even easier!
🚀 Improvements:
- Added a cancellation interface for PdfPagesExtractor calls. Now you can cancel extracting pages from large PDFs and thus don't need to wait until the end of the process. Look for property cancelCallback: LongOperationCancelCallback inside fun pagesFromPdf(pdfFile, cancelCallback).
- Beta: An improved Check Recognizer that now supports further bank layouts from different countries (e.g Kuwait, India, Australia). The recognizer is available as Classic and RTU UI components. Please note that this feature is still in beta. Furthermore, due to the renaming of the feature from "Cheque" to "Check", some classes and API methods have been renamed as well as new classes have been introduced.

- Added new methods DocumentScannerConfiguration.setForceMaxSnappingSize() and ScanbotCameraXView.setForceMaxSnappingSize() that force the maximum available snapping size and apply the same aspect ratio to the preview. Works only with ScanbotCameraXView or with CameraX enabled in the RTU UI. Disabled by default, thus ScanbotCameraXView shows a preview and makes snaps with an aspect ratio closest to the display's dimensions.
- Added support for the GS1 barcode document format, see Gs1Document.
- Added a class BarcodeDocumentParser to parse a string into a supported barcode document type.
- Added a new method GenericDocumentScannerConfiguration.setExcludedFieldTypes() that can be used to set fields that should be excluded from the scanning process altogether, e.g. for security reasons.
🚀 Improvements:
- Improved the UX of the DocumentScannerActivity screen. Now the SnapFlashView animation and the pausing of the preview happens only after the image was captured. Previously it could result in blurry images.
- All the date fields returned by GenericDocumentRecognizer now have a ValidationStatus. Fields with ValidationStatus = Invalid will not be shown in the list of fields for GenericDocumentRecognizerActivity.
