Type alias SymbologySpec

SymbologySpec: {
    checksumMode?: number;
    maxLen?: number;
    minLen?: number;
    name: SymbologyName;
    qz?: number;
}

For variable-length symbologies, min/max length can be specified in addition to the symbology.

Optional checksumMode?: number
The mode to use for symbologies which support an optional checksum mechanism.

Setting the mode to 0 or leaving it unset disables processing of the checksum. 1 will expect the check digit to be present, validate the barcode data against it, and strip it from the transmitted data. 2 will validate and also transmit the check digit along with the data portion.
Remarks
Setting this option to 1 or 2 requires that all barcodes of this symbology include a check digit. Barcodes that lack the check digit will not be readable anymore.

Default Value
```
0
```
Optional maxLen?: number
The maximum length of the barcode, only has an effect for variable-length symbologies.
Optional minLen?: number
The minimum length of the barcode, only has an effect for variable-length symbologies.
name: SymbologyName
The name of the symbology.
Optional qz?: number
The minimum length of the leading and trailing quiet zone for this symbology, expressed as multiples of X.

Remarks
There is rarely a need to change the default.
