Added VinRecognizer for scanning VIN (Vehicle Identification Number) barcodes
Added unified BarcodeRecognizer for scanning various tipes of barcodes
ZXingRecognizer and BarDecoderRecognizer are deprecated, BarcodeRecognizer should be used for all barcode types that are supported by these recognizers
added support for reading mirrored QR codes:
affects all recognizers that perform QR code scanning
introduced GlareDetector which is by default used in all recognizers whose settings implement GlareDetectorOptions:
when glare is detected, OCR will not be performed on the affected document position to prevent errors in the extracted data
if the glare detector is used and obtaining of glare metadata is enabled in MetadataSettings, glare status will be reported to MetadataListener
glare detector can be disabled by using setDetectGlare(boolean) method on the recognizer settings
added QuadDetectorWithSizeResult which inherits existing QuadDetectorResult:
it's subclasses are DocumentDetectorResult and MRTDDetectorResult
returns information about physical size (height) in inches of the detected location when physical size is known
added support for characters { and } in OCR_FONT_VERDANA to OCR engine
Minor API changes:
Date fields in recognition results are returned as com.microblink.results.date.Date class which represents immutable dates that are consisted of day, month and year
OcrLine.getChars() method returns CharWithVariants array. OCR char is defined by all its parameters (value, font, position, quality, etc.) and for each resulting char it is possible to have multiple variants. For example it is possible to have same char value with different font.
RegexParserSettings and RawParserSettings now work with AbstractOCREngineOptions, which is a base class of BlinkOCREngineOptions
default engine options returned by method getOcrEngineOptions for both parser settings return instance of BlinkOCREngineOptions
BlinkOCRRecognizerSettings is now deprecated and will be removed in v4.0.0
use DetectorRecognizerSettings to perform scanning of templated documents
use BlinkInputRecognizerSettings for segment scan or for full-screen OCR
until v4.0.0, BlinkOCRRecognizerSettings will behave as before, however you are encouraged to update your code not to use it anymore
DocumentClassifier interface is moved from com.microblink.recognizers.blinkocr to com.microblink.recognizers.detector package and DocumentClassifier.classifyDocument() now accepts DetectorRecognitionResult as parameter for document classification
Improvements for existing features:
improved TopUpParser:
added option to return USSD code without prefix
improved IbanParser:
improved extraction of IBANs without prefix and introduced setAlwaysReturnPrefix option to always return prefix (country code)
added support for french IBANs
enabled reading of Pdf417 barcodes having width/height bar aspect ratio less than 2:1
improved date parsing:
affects date parser and all recognizers which perform date parsing
Bug fixes:
fixed returning of images inside TemplatingAPI for frames when document was not correctly detected
