Method Detail

• scanBitmap

  @Synchronized() final GenericDocumentScanResult scanBitmap(Bitmap bitmap, Boolean shouldRecognize, Integer orientation)

  Scan image to detect ID card and data on it

  Parameters:

  bitmap - image

  shouldRecognize - whether to recognize field and their data on ID card.

  orientation - image orientation.

• scanJpeg

  @Synchronized() final GenericDocumentScanResult scanJpeg(ByteArray jpeg, Boolean shouldRecognize, Integer orientation)

  Scan image to detect ID card and data on it

  Parameters:

  jpeg - image in form of jpeg-encoded byte array

  shouldRecognize - whether to recognize field and their data on ID card.

  orientation - image orientation.

• scanNv21

  @Synchronized() final GenericDocumentScanResult scanNv21(ByteArray nv21, Integer width, Integer height, Integer orientation, Rect finderRect, Boolean shouldRecognize)

  Scan image to detect ID card and data on it

  Parameters:

  nv21 - image in form of nv21-encoded byte array

  width - image width, pixels

  height - image height, pixels

  orientation - image orientation.

  finderRect - if non-null - perform scanning only in given area.

  shouldRecognize - whether to recognize field and their data on ID card.

• setAcceptedSharpnessScore

  @Synchronized() final Unit setAcceptedSharpnessScore(Float acceptedSharpnessScore)

  Accepted minimal sharpness score. Images with a score less than that will be rejected with RecognitionStatus::ErrorTooBlurry.

  Default is 0

  0 - any image will be accepted. 80 - a good compromise; the recommended setting. 100 - only very sharp images will be accepted.

• setAcceptedDocumentTypes

  @Synchronized() final Unit setAcceptedDocumentTypes(List<GenericDocumentScanResult.DocumentType> acceptedDocumentTypes)

  Accepted document types. All other document types will be ignored.

  By default - all document types are accepted.

• setExcludedFieldTypes

  @Synchronized() final Unit setExcludedFieldTypes(Set<String> excludedFieldTypes)

  Set of secure fields which should be excluded from scanning process. All other fields will be scanned as usual.

  By default - empty, and all fields are scanned.

• clear

  @Synchronized() final Unit clear()

  Clears the result accumulation cache (see accumulateFrames).
