20 * Represents some type of metadata about the result of the decoding that the decoder
21 * wishes to communicate back to the caller.
25 public enum ResultMetadataType {
28 * Unspecified, application-specific metadata. Maps to an unspecified {@link Object}.
33 * Denotes the likely approximate orientation of the barcode in the image. This value
34 * is given as degrees rotated clockwise from the normal, upright orientation.
35 * For example a 1D barcode which was found by reading top-to-bottom would be
36 * said to have orientation "90". This key maps to an {@link Integer} whose
37 * value is in the range [0,360).
42 * <p>2D barcode formats typically encode text, but allow for a sort of 'byte mode'
43 * which is sometimes used to encode binary data. While {@link Result} makes available
44 * the complete raw bytes in the barcode for these formats, it does not offer the bytes
45 * from the byte segments alone.</p>
47 * <p>This maps to a {@link java.util.List} of byte arrays corresponding to the
48 * raw bytes in the byte segments in the barcode, in order.</p>
53 * Error correction level used, if applicable. The value type depends on the
54 * format, but is typically a String.
56 ERROR_CORRECTION_LEVEL,
59 * For some periodicals, indicates the issue number as an {@link Integer}.
64 * For some products, indicates the suggested retail price in the barcode as a
65 * formatted {@link String}.
70 * For some products, the possible country of manufacture as a {@link String} denoting the
71 * ISO country code. Some map to multiple possible countries, like "US/CA".
