Method Detail

decode

public DecoderResult decode(boolean[][] image)
                     throws java.lang.Exception

Convenience method that can decode a QR Code represented as a 2D array of booleans. "true" is taken to mean a black module.

Parameters:

image - booleans representing white/black QR Code modules

Returns:

text and bytes encoded within the QR Code

Throws:

java.lang.Exception - if something wrong

decode

public DecoderResult decode(byte[][] bytes)
                     throws java.lang.Exception

Convenience method that can decode a QR Code represented as a 2D array of booleans. "true" is taken to mean a black module.

Parameters:

bytes - bytes representing white/black QR Code modules

Returns:

text and bytes encoded within the QR Code

Throws:

java.lang.Exception - if something wrong

decode

public DecoderResult decode(BitMatrix bits)
                     throws java.lang.Exception

Decodes a QR Code represented as a BitMatrix. A 1 or "true" is taken to mean a black module.

Parameters:

bits - booleans representing white/black QR Code modules

Returns:

text and bytes encoded within the QR Code

Throws:

java.lang.Exception - if the QR Code cannot be decoded or if error correction fails

encode

public QRCode encode(java.lang.String content,
                     ErrorCorrectionLevel ecLevel)

encoding Content to QRCode

Parameters:

content - text to encode

ecLevel - error correction level to use

Returns:

representing the encoded QR code QRCode
