TdxQRCodeErrorCorrectionLevel Enum

Enumerates available amounts of redundant information in QR Codes generated by the barcode control.

Declaration

    eclH
);

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.
