zext.plantuml.com.google.zxing.DecodeHintType
public final class DecodeHintType extends Object
Encapsulates a type of hint that a caller may pass to a barcode reader to help it more quickly or accurately decode it. It is up to implementations to decide what, if anything, to do with the information that is supplied.

  • Field Details

    • OTHER

    • POSSIBLE_FORMATS

      public static final DecodeHintType POSSIBLE_FORMATS
      Image is known to be of one of a few possible formats. Maps to a Vector of BarcodeFormats.

    • TRY_HARDER

      public static final DecodeHintType TRY_HARDER
      Spend more time to try to find a barcode; optimize for accuracy, not speed. Doesn't matter what it maps to; use Boolean.TRUE.
