Enum Class WQrCode.ErrorCorrectionLevel

java.lang.Object

java.lang.Enum<WQrCode.ErrorCorrectionLevel>

eu.webtoolkit.jwt.WQrCode.ErrorCorrectionLevel

All Implemented Interfaces:

Serializable, Comparable<WQrCode.ErrorCorrectionLevel>, Constable

Enclosing class:

WQrCode

public static enum WQrCode.ErrorCorrectionLevel
extends Enum<WQrCode.ErrorCorrectionLevel>

Represents the different error correction levels for QR codes.

The error correction level impacts how much erroneous squares the QR code can contains without becoming unreadable.

For most digital use, the default of LOW is sufficient. Higher levels can be considered for printed out media.
