TDataBlock.getDataBlocks Method
Definition
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.
Delphi
class function getDataBlocks(const rawCodewords: TArray<Byte>; const version: TVersion; const ecLevel: TErrorCorrectionLevel): TArray<TDataBlock>Parameters
- rawCodewords
- TArray<Byte>
bytes as read directly from the QR Code
- version
- TVersion
version of the QR Code
- ecLevel
- TErrorCorrectionLevel
error-correction level of the QR Code
Returns
TArray<TDataBlock>
{@link TDataBlock}s containing original bytes, "de-interleaved" from representation in the QR Code
