Methods

decode(BinaryBitmap)

Locates and decodes a QR code in an image.

a String representing the content encoded by the QR code

public Result decode(BinaryBitmap image)

Parameters

image BinaryBitmap

Returns

Result

decode(BinaryBitmap, IDictionary<DecodeHintType, object>)

Locates and decodes a barcode in some format within an image. This method also accepts hints, each possibly associated to some data, which may help the implementation decode.

public Result decode(BinaryBitmap image, IDictionary<DecodeHintType, object> hints)

Parameters

image BinaryBitmap

image of barcode to decode

hints IDictionary<DecodeHintType, object>

passed as a IDictionary<TKey, TValue> from DecodeHintType to arbitrary data. The meaning of the data depends upon the hint type. The implementation may or may not do anything with these hints.

Returns

Result

String which the barcode encodes

getDecoder()

Gets the decoder.

protected Decoder getDecoder()

Returns

Decoder

reset()

Resets any internal state the implementation has after a decode, to prepare it for reuse.
