$rsDecoder
$rsDecoder :
<p>The main class which implements QR Code decoding -- as opposed to locating and extracting the QR Code from an image.</p>
decodeImage( $image, $hints = null) : \Zxing\Qrcode\Decoder\text
<p>Convenience method that can decode a QR Code represented as a 2D array of booleans.
"true" is taken to mean a black module.
| $image | ||
| $hints |
if the QR Code cannot be decoded
if error correction fails
and bytes encoded within the QR Code
decodeBits( $bits, $hints = null) : \Zxing\Qrcode\Decoder\text
<p>Decodes a QR Code represented as a {@link BitMatrix}. A 1 or "true" is taken to mean a black module.</p>
| $bits | ||
| $hints |
if the QR Code cannot be decoded
if error correction fails
and bytes encoded within the QR Code
correctErrors( $codewordBytes, $numDataCodewords)
<p>Given data and error-correction codewords received, possibly corrupted by errors, attempts to correct the errors in-place using Reed-Solomon error correction.</p>
| $codewordBytes | ||
| $numDataCodewords |
if error correction fails
