Definition

Unit:: ZXing.QrCode.Internal.DataBlock

Package:: QRCodeReader_FMX

Encapsulates a block of data within a QR Code. QR Codes may split their data into multiple blocks, each of which is a unit of data and error-correction codewords. Each is represented by an instance of this class.

Methods

getDataBlocks(TArray<Byte>, TVersion, TErrorCorrectionLevel)

When QR Codes use multiple data blocks, they are actually interleaved. That is, the first byte of data block 1 to n is written, then the second bytes, and so on. This method will separate the data into original blocks.

Fields

Fcodewords
FnumDataCodewords
