CIQRCodeDescriptorMBS.errorCorrectedPayload as MemoryBlock

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	CoreImage	MBS MacCI Plugin	17.4	✅ Yes	❌ No	❌ No	✅ Yes	All

The error-corrected codewords that comprise the QR code symbol.

QR Codes are formally specified in ISO/IEC 18004:2006(E). Section 6.4.10 "Bitstream to codeword conversion" specifies the set of 8-bit codewords in the symbol immediately prior to splitting the message into blocks and applying error correction.

During decode, error correction is applied and if successful, the message is re-ordered to the state immediately following "Bitstream to codeword coversion." The errorCorrectedPayload corresponds to this sequence of 8-bit codewords.

property	CoreImage	MBS MacCI Plugin	17.4	✅ Yes	❌ No	❌ No	✅ Yes	All

The version property corresponds to the size of the QR Code.

QR Codes are square. ISO/IEC 18004 defines versions from 1 to 40, where a higher symbol version indicates a larger data carrying capacity. This field is required in order to properly interpret the error corrected payload.
