Remarks
Each codeword occupies a single byte, and the “Reed-Solomon” error correction algorithm can use one of the four error correction levels listed in the following table:
Value | Description |
---|---|
eclL | Low redundancy level. Only 7% of codewords can be restored. |
eclM | Medium redundancy level (the default value). In this case, 15% of codewords can be restored. |
eclQ | 25% of codewords can be restored. |
eclH | High redundancy level. 30% of codewords can be restored. |
Note
The higher the error correction level, the lower the storage capacity of the generated QR code.
The TdxQRCodeErrorCorrectionLevel type is referenced by the ErrorCorrectionLevel property provided by the TdxBarCodeQRCodeSymbology class.
