      public boolean shouldAllowInvalidCardNumber()
      Whether invalid card number is accepted. By default, this is set to 'false'

    • setHandScaleThreshold

      public void setHandScaleThreshold(@FloatRange(from=0.0,to=1.0) float handScaleThreshold)
      Hand scale is calculated as a ratio between area of hand mask and document mask. `handScaleThreshold` is the minimal value for hand to be accepted as significant. By default, this is set to '0.15'.

    • getHandScaleThreshold

      @FloatRange(from=0.0, to=1.0) public float getHandScaleThreshold()
      Hand scale is calculated as a ratio between area of hand mask and document mask. `handScaleThreshold` is the minimal value for hand to be accepted as significant. By default, this is set to '0.15'.

    • setEncodeFullDocumentImage

      public void setEncodeFullDocumentImage(boolean encodeFullDocumentImage)
      Description copied from interface: EncodeFullDocumentImagesOptions
