\Zxing\Qrcode\DecoderBitMatrixParser

__construct()

__construct( $bitMatrix) : mixed

Parameters

Throws

\Zxing\FormatException

if dimension is not >= 21 and 1 mod 4

Returns

readCodewords()

readCodewords() : \Zxing\Qrcode\Decoder\bytes

<p>Reads the bits in the {@link BitMatrix} representing the finder pattern in the correct order in order to reconstruct the codewords bytes contained within the QR Code.</p>

Throws

\Zxing\FormatException

if the exact number of bytes expected is not read

Returns

encoded within the QR Code

readFormatInformation()

readFormatInformation() : mixed

<p>Reads format information from one of its two locations within the QR Code.</p>

Throws

\Zxing\FormatException

if both format information locations cannot be parsed as the valid encoding of format information

Returns

readVersion()

readVersion() : mixed

<p>Reads version information from one of its two locations within the QR Code.</p>

Throws

\Zxing\FormatException

if both version information locations cannot be parsed as the valid encoding of version information

Returns

remask()

remask() : void

Revert the mask removal done while reading the code words. The bit matrix should revert to its original state.

setMirror()

setMirror(\Zxing\Qrcode\Decoder\Whether  $mirror) : void

Prepare the parser for a mirrored operation.

This flag has effect only on the {@link #readFormatInformation()} and the {@link #readVersion()}. Before proceeding with {@link #readCodewords()} the {@link #mirror()} method should be called.

Parameters

mirror()

mirror() : void

Mirror the bit matrix in order to attempt a second reading.

copyBit()

copyBit(mixed  $i, mixed  $j, mixed  $versionBits) : mixed

Parameters

Returns
