Android

🎉 New:
- General:
  - ImageRef: optimize flag added to SaveImage and EncodeImage. When set to true, the encoder spends additional time to improve JPEG output quality.
  - Added support for custom accessibility state strings for scanner screens that use ActionBarConfiguration.
  - Added support for navigation on polygon corners with keyboard for EditPolygonImageView.
  - Added parameter CameraConfiguration.CameraPreviewAspectRatio to support different preview aspect ratios in FitIn mode in RTU UI screens.
- Document Scanner:
  - Added DocumentEnhancer with a Straighten method that removes crinkles, creases, folds, and curl from document photos. It is enabled by default in the RTU UI and automatically applied in auto-cropping flows. See the Document Enhancer documentation for details.
  - Document API: Added new field StraighteningParameters to the Page object.
  - Document API: Added new parameter NewStraighteningParameters to the Page#apply() function.
  - Support for recognizing cropped documents. DocumentScannerParameters now includes AlreadyCroppedScoreThreshold, and DocumentDetectionScores now includes alreadyCroppedScore. In single-shot mode, if no document is detected and the score exceeds this threshold, a new DocumentDetectionStatus value OK_BUT_ALREADY_CROPPED is returned, along with a quad (points) corresponding to the image corners. This feature is supported by all downstream components of the Document Scanner (Check Scanner, Credit Card Scanner, Document Classifier, Document Data Extractor, and Medical Certificate Scanner).
  - Added a parameter to set the background color for the PreviewButton button in the bottom bar on the RTU UI Camera Screen.
- Image Processing:
  - New ColorDocumentShadowRemovalFilter capable of removing shadows from documents without damaging text, barcodes, or images.
- Document Quality Analyzer:
  - A new Document Quality Analyzer algorithm was introduced. The result object's Quality property can now be Acceptable, Unacceptable, or Uncertain, indicating whether a user-provided document image meets the required quality standard. Advanced configuration is available using the QualityAnalysisModel parameter, which allows the Document Quality Analyzer to be fine-tuned for specific use cases using an external script. This capability is currently in closed beta. To request access and obtain the script, sign up here.
  - Added a threshold parameter for categorizing documents into three classes: Acceptable, Unacceptable, and Uncertain.
  - Added the InputScales option to run the model at multiple resolutions and automatically select the best result.
  - Added the InputScaleThresholdToProcessEntireImage option to run the Document Quality Analyzer on the entire image, even when MinProcessedFraction and MaxProcessedFraction are not equal to 1 for small input scales.
  - The resulting BestInputScale is now included in the output.
  - Added CompatibilityMode property to DocumentQualityAnalyzerConfiguration to allow running the legacy (v8) document quality analysis engine.
- Document Data Extractor:
  - Added support for Romanian, Italian, Turkish, and Polish ID cards.
- Check Scanner:
  - Added support for more USA check formats. Newly supported formats: (TT)xxx(TT)xxxx(UU)xxx(UU), and the ones enumerated in the MICR line identification documentation.
  - Added support for xxx-xxx-x account number format for Canadian checks.
- Barcode Scanner:
  - Added a TwoDDecodingMode to the barcode configuration. It defaults to HighEffort and can be set to LowEffort for very low-power devices requiring higher frame rates.
🚀 Improvements:
- General:
  - Improved behavior of accessibility descriptions for the action bar's zoom button in RTU UI scanners.
- Document Scanner:
  - Updated document detector models with improved accuracy.
  - Partially visible documents are now supported in all processing modes. Auto and single-shot modes now return the ErrorPartiallyVisible document status when only 1–3 document corners are visible in the input image and the scanner is configured with AllowPartiallyVisibleDocuments = true.
  - Improved the behavior when the page limit was reached in the RTU UI single-page mode.
  - Improved the behavior of the Acknowledge Screen for more precise error hints control.
  - Document Scanner RTU UI and Document Cropping RTU UI now use Document Enhancer under the hood.
    - In Document Scanner RTU UI, the enhancer is controlled using the DocumentStraighteningParameters configuration.
    - In Document Cropping RTU UI there were no configuration changes. Instead, the enhancer uses the same configuration that is stored in the Page's metadata. For more information, see the Document Enhancer documentation.
  - Added a check for document detection status after the image is snapped or imported to determine whether cropping is required.
- PDF & TIFF Generation:
  - PdfImagesExtractor and PdfPagesExtractor now use the Result API for consistent error handling.
  - Enhanced PdfImagesExtractor with new extract methods supporting ImageRef processing and callback-based page control.
  - Added PdfImageProcessingCallback support to PdfPagesExtractor for image processing before page storage.
- Document Quality Analyzer:
  - Increased the default threshold for MinRequiredOrientationConfidence to 0.9, reducing false positives in orientation estimation.
  - Orientation detection now considers text at any angle, not just within ±10° of 0°, 90°, 180°, or 270°. For orientation estimation, text at any angle is rounded to the nearest multiple of 90° — for example, a 30° angle yields a predicted orientation of 0°.
  - Improved performance on very bright or very dark images.
- OCR Engine:
  - New model with better performance for German diacritics and ß/ẞ recognition.
  - Added support for Turkish, Polish, Italian, and Romanian alphabets.
  - Increased accuracy without increasing inference time.
- VIN Scanner:
  - Live or single-shot mode, derived from the input image, is now propagated to the internal barcode scanner.
- Document Data Extractor:
  - Reduced the likelihood of reading incorrect values for eye color on German ID cards (e.g., GRUN instead of GRÜN).
  - Document types are now classified using an ML model, resulting in higher quality and faster recognition.
- Check Scanner:
  - For Canadian checks, the scanner now allows more whitespace characters in the MICR line.
- Credit Card Scanner:
  - Various improvements to check digit validation and aspect ratio handling.
- Barcode Scanner:
  - Clean barcodes (QR Code, DataMatrix, and all 1D formats) are detected faster in single-shot mode and can be detected without a quiet zone.
  - Significantly improved decoding performance for truncated PDF417 barcodes.
  - Reduced the false positive rate for barcode formats EAN-8, EAN-13, and UPC-A when EnableOneDBlurScanner is enabled (now the default).
  - Improved recall and precision for barcode formats EAN-8, EAN-13, UPC-A, and UPC-E when ink spread is present.
  - Data Matrix codes can now be scanned under harsher conditions. With HighEffort enabled, scanning works even on curved surfaces or when the code is partially occluded.
  - Reduced the number of false-positive Codabar barcodes when scanning in live mode and the barcode is only partially visible.
🐞 Bug fixes:
- General:
  - Fixed a crash with ImageRef.SaveImage when default Android encryption was enabled.
  - Fixed RTU UI top bars behavior with hidden back buttons.
  - Fixed incorrect viewfinder aspect ratio calculations when CameraPreviewMode was set to FitIn.

  - Fixed an issue where documents containing Cyrillic text were sometimes classified incorrectly.
- Check Scanner:
  - Fixed missing support for longer check number fields on Canadian checks.
- Barcode Scanner:
  - Fixed an arithmetic exception occurring when processing images with very small heights (lower than 5 px) in single-shot mode.
  - Fixed the orientation of quads for barcode formats DataBar and DataBar Expanded with multiple stacks.
  - Fixed a rare issue with the DataBar barcode format, which could lead to a crash.
⚠️ Breaking changes:
- General:
  - All APIs that receive or return normalized coordinates of points assume that normalization is performed by dividing image coordinates by (width - 1, height - 1) instead of (width, height). This ensures that rotation operations that are performed on the normalized coordinates are mathematically correct. Callers that call functions that receive normalized coordinates or process results with normalized points and perform conversion on their own should adjust their implementations.
  - The Scanbot SDK now requires Android Gradle plugin 8.9.1 or higher. Update your AGP version to prevent build errors.
  - Changed the behavior of BarcodeScannerView and DocumentCameraView in onCameraOpen() callbacks to allow disabling detection on the frame from within these callbacks.
  - Removed Tesseract features to decrease the Scanbot SDK size.
- Document Scanner:
  - Removed AcknowledgementScreenConfiguration.MinimumQuality parameter. Use DoQA configuration to change document acceptance levels.
  - Updated the Acknowledge Screen logic in the RTU UI Document Scanner to properly handle document quality scenarios. The unacceptableQuality acknowledgment mode now shows the Acknowledge Screen for "document not found" cases when documentNotFoundWarning.visible is configured to true. This may change the behavior for applications relying on the previous logic where "document not found" cases were always bypassed in unacceptableQuality mode.
  - Improved the button visibility logic on the Acknowledge Screen. The proceed anyway button visibility now correctly considers both the specific button configuration and the global proceedAnywayButton.visible setting. This may affect existing configurations that rely on the previous behavior. By default, when the image is unacceptable, the proceed anyway button is no longer shown unless explicitly configured to be visible (see screens.camera.acknowledgement.bottomBar.proceedAnywayButton.unacceptableQuality).
  - Fixed a bug in PolygonHelper:
    - the implementation of the method GetFullPolygon had the incorrect order of vertices — a potentially breaking change, check the usages of this helper method in your code;
    - the method GetFullPolygonCCW was renamed to GetFullPolygonCcw, and its implementation was adjusted to fix a bug with the incorrect order of vertices.
  - Renamed the Style field to Title in TextWithBadgeButtonMode and the Text field to Title in TextButtonMode.
  - Removed AcknowledgementScreenConfiguration.BadImageHint. Use DocumentNotFoundWarning, UncertainQualityWarning, and UnacceptableQualityWarning parameters to control the hints shown in the Acknowledge Screen.
  - Strings were introduced for the Acknowledge Screen in the RTU UI Document Scanner to support the new document quality scenarios. Update custom translations for the Acknowledge Screen to include these strings: proceedAnywayButtonDocumentNotFound, proceedAnywayButtonUnacceptableQuality, proceedAnywayButtonUncertainQuality, acknowledgementWarningDocumentNotFound, acknowledgementWarningUnacceptableQuality, and acknowledgementWarningUncertainQuality.
  - Passing null to the polygon parameter in Page.apply() no longer resets the page polygon — the value is silently ignored.
- PDF & TIFF Generation:
  - When adding a PNG file to a PDF, the image is now always re-encoded as JPEG. Previously, this occurred only in specific situations.
  - ImageUrlsFromPdf() method in PdfImagesExtractor was renamed to Extract().
  - PdfImagesExtractor methods now return Result types instead of throwing IOException or OperationCancelledException.
  - PagesFromPdf() method in PdfPagesExtractor was renamed to Extract().
  - PdfPagesExtractor.Extract() now returns Result<List<String>> instead of throwing exceptions.
- Document Quality Analyzer:
  - The configuration properties QualityThresholds and QualityIndices have been renamed to QualityLevelThresholds and QualityLevelIndices. The renamed properties are now deprecated; use the new QualityAnalysisModel property instead.
  - The DetectOrientation option has been removed. Orientation detection now always runs.
  - The InspectSmallText option has been removed.
- Document Data Extractor:
  - When initialized with no accepted document types, or only invalid ones, and with MRZ fallback disabled, an InvalidArgument error is now thrown.
- Check Scanner:
  - Leading and trailing whitespace for all USA check fields is now trimmed.
  - A group of numbers in the Canadian check account number section preceding the first dash is now treated as a designation number only if its length is 4. Previously, a sequence of any length was treated as a designation number. Dashes present in the MICR line are preserved in the Account Number parsed field.
⚠️ Deprecations:
- General:
  - AESEncryptedFileIOProcessor is deprecated and will be removed in future versions. Use AesGcmEncryptedFileIoProcessor instead.
- Document Quality Analyzer:
  - The DocumentQuality enum and result object property are deprecated; use DocumentQualityAssessment instead.
  - The DocumentQualityAnalyzerResult.DocumentFound property is now deprecated. This deprecated property indicates if too few characters are detected. The new DocumentQualityAssessment will be reported as Uncertain in this situation. If this is not suitable for your use case, consider using the Document Scanner instead to determine if an image contains a document. In the RTU UI Document Scanner, the DocumentNotFoundWarning case is now based on the Document Scanner output.
  - QualityLevelThresholds and QualityLevelIndices are deprecated (see Breaking changes).

  - Introduced a new algorithm for recognizing 1D symbologies, enhancing performance with blurred and distant barcodes. This feature is enabled by default but can be turned off using the EnableOneDBlurScanner property in barcode format configurations on low-power devices if necessary.
  - Added a new BarcodeScannerEngineMode: NextGenMaxDistance, which is optimized for scanning from far distances on very high-power devices with a 4K video stream.
  - All 1D barcode formats can be configured with a new OneDConfirmationMode which is Thorough by default. Setting it to Minimal or None could lead to higher recall in difficult scenarios, but could also cause more false positives.
🚀 Improvements:
- General:
  - All OCR-based features now benefit from new OCR models that are optimized for speed and accuracy.
  - The "Created TensorFlow Lite XNNPACK delegate for CPU." log is no longer an output in production builds.
  - If a global or custom encrypter is set when an image is created from a file, it will be automatically detected if the image is encrypted or not. Note that now EncryptionMode is NOT ignored if a custom encrypter/decrypter is used.
  - When creating an ImageRef from Android Bitmap or from a .png file containing an alpha channel, they are blended with a user specified canvas color instead of simply discarding the alpha channel. It is possible to select whether to use a White or Black background in BasicImageLoadOptions, RawImageLoadOptions, PathImageLoadOptions, and BufferImageLoadOptions.
  - All configurations for scanners can now be set directly on scanner creation, e.g. IO.Scanbot.Sdk.ScanbotSDK#.CreateBarcodeScanner(BarcodeScannerConfiguration).
  - OCR engine, PDF, and TIFF generators no longer create content URIs content copies in the cache directory for processing.
  - Optimized memory usage of Scanbot Camera components.

⚠️ Breaking changes:
- Android:
  - 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.
