Symbology Settings in WPF Barcode (SfBarcode)

4 May 20214 minutes to read

Each Barcode symbol can be associated with optional settings that may affect that specific bar code. The code sample below shows the settings of a code39 Barcode.

  • HTML
    • <sync:SfBarcode.SymbologySettings>

         <sync:Code39Setting BarHeight="45" EnableCheckDigit="False" EncodeStartStopSymbols="True" NarrowBarWidth="1" ShowCheckDigit="False"/>

</sync:SfBarcode.SymbologySettings>

    1D Barcode settings

    The one dimensional barcodes have some of the settings in common, such as BarHeight which modifies the height of the bars and NarrowBarWidth which modifies the width ratio of the wide and narrow bars.

  • HTML
    • <sync:SfBarcode.SymbologySettings>

         <sync:Code39Setting BarHeight="45" NarrowBarWidth="1"/>

</sync:SfBarcode.SymbologySettings>

    The one dimensional barcodes also has the error detection settings. The EnableCheckDigit property enables the redundancy check using a check digit, the decimal equivalent of a binary parity bit. It consists of a single digit computed from the other digits in the message. The check digit can be shown in the barcode or kept hidden by using the ShowCheckDigit property.

    The EncodeStartStopSymbols property adds Start and Stop symbols to signal a bar code reader that a bar code has been scanned.

  • HTML
    • <sync:SfBarcode.SymbologySettings>

         <sync:Code39Setting EnableCheckDigit="False" EncodeStartStopSymbols="True" ShowCheckDigit="False"/>

</sync:SfBarcode.SymbologySettings>

    2D Barcode Settings

    The two dimensional barcodes have a common XDimension property which modifies the block size of a two dimensional barcode.

    DataMatrix Barcode settings

    The DataMatrix barcode settings has the properties to modify the encoding and size of the DataMatrix barcode.

  • HTML
    • <sync:SfBarcode.SymbologySettings>

         <sync:DataMatrixSetting XDimension="8" Encoding="ASCIINumeric” Size="Size104x104" />

</sync:SfBarcode.SymbologySettings>

    Encoding

    The encoding of the DataMatrix barcode can be modified using the ‘Encoding’ property. The DataMatrixEncoding enumeration has the following four encoding schemes.

    • ASCII
    • ASCIINumeric
    • Auto
    • Base256

    Size

    The DataMatrix Barcode settings allow the user to specify the size of the barcode from a set of predefined sizes available in the DataMatrixSize enumeration.

    QRBarcode settings

    The QRBarcode settings has properties to modify the version, error correction level and Input mode of the QRBarcode.

  • HTML
    • <sync:SfBarcode.SymbologySettings>

    <sync:QRBarcodeSetting XDimension="8" ErrorCorrectionLevel="High” InputMode="BinaryMode”  Version="Auto" />

</sync:SfBarcode.SymbologySettings>

    Version

    The QR Barcode uses version from 1 to 40.Version 1 measures 21 modules x 21 modules, Version 2 measures 25 modules x 25 modules and so on increasing in steps of 4 modules per side up to Version 40 which measures 177 modules x 177 modules. Each version has its own capacity. By default the QR Version is Auto, which will automatically set the version according to the input text length.

    Error correction level

    The QR Barcode employs error correction to generate a series of error correction codewords which are added to the data code word sequence in order to enable the symbol to withstand damage without loss of data. There are four user–selectable levels of error correction, as shown in the table, offering the capability of recovery from the following amounts of damage. By default the Error correction level is Low.

    Error Correction Level Table

    Error Correction Level Recovery Capacity % (approx.)
    L 7
    M 15
    Q 25
    H 30

    Input mode

    There are three modes for the input as defined in the table. Each mode supports the specific set of Input characters. User may select the most suitable input mode. By default the Input mode is Binary Mode.

    Input Mode Table

    Input Mode Possible characters
    Numeric Mode 0,1,2,3,4,5,6,7,8,9
    Alphanumeric Mode 0–9, A–Z (upper-case only), space, $, %, *, +, -,., /, :
    Binary Mode Shift JIS characters
