Cross-Platform Class Library	QRCodeGenerator.ErrorCorrectionLevel

Remarks

Codewords are 8 bits long and use the “Reed–Solomon” error correction algorithm with four error correction levels. The higher the error correction level, the less storage capacity.

The QRCodeErrorCorrectionLevel enumeration values are used to set the QRCodeGenerator.ErrorCorrectionLevel property.

Note

If the QRCodeGenerator.Logo property is specified, the QRCodeErrorCorrectionLevel enumeration values are halved.
