# Symbology Settings

Each and every Barcode symbology can be personalized with optional settings that may affect the appearance of specific Barcode.

## One Dimensional Barcode settings

One dimensional Barcodes can be customized by using the following properties and they are commonly used for all categories of supported one dimensional Barcodes.

- By setting the
`BarHeight`

property, the height of linear bars can be changed. - By setting the
`NarrowBarWidth`

property, the width ratio of wide and narrow bars can be customized.

One dimensional Barcodes can also have error detection settings.

- By enabling the
`EncodeStartStopSymbols`

property, start and stop symbols are added to signal a Barcode reader that a Barcode has been scanned. - The
`EnableCheckDigit`

property enables or disables the redundancy check by using a check digit that is the decimal equivalent of a binary parity bit. - With the help of
`ShowCheckDigit`

property, the check digit can be shown or hidden.

The following code example shows how to change the settings of `Code39`

linear Barcode.

```
SFCode39Settings settings = new SFCode39Settings();
settings.BarHeight = 100;
settings.NarrowBarWidth = 2;
settings.EncodeStartStopSymbols = true;
settings.EnableCheckDigit = false;
settings.ShowCheckDigit = false;
```

Similarly, you can specify the settings of other linear Barcodes corresponding to specified symbology.

## Two Dimensional Barcode Settings

Two dimensional Barcodes are customized by using `XDimension`

property that modifies its block size and it is commonly used for all kinds of supported two dimensional Barcodes.

### Data Matrix Settings

The Data Matrix symbology can be customized with the help of the following settings.

```
SFDataMatrixSettings settings = new SFDataMatrixSettings();
settings.XDimension = 8;
settings.Size = SFBarcodeDataMatrixSize.SFBarcodeDataMatrixSizeAuto;
settings.Encoding = SFBarcodeDataMatrixEncoding.SFBarcodeDataMatrixEncodingAuto;
```

- The
`Encoding`

property is used to specify the encoding technique from enumeration of`SfDataMatrixEncoding`

that contains encoding techniques such as ASCII, ASCIINumeric, Auto and Base256. - The
`Size`

property allows the user to specify the size of the Barcode from a set of predefined sizes available in the`SFDataMatrixSize`

enumeration.

### QR Code Settings

The Data Matrix symbology can be customized by using the following settings.

```
SFQRBarcodeSettings settings = new SFQRBarcodeSettings();
settings.XDimension = 5;
settings.InputMode= SFBarcodeQRInputMode.SFBarcodeQRInputModeBinary;
settings.ErrorCorrectionLevel = SFBarcodeQRErrorCorrectionLevel.SFBarcodeQRErrorCorrectionLevelLow;
settings.Version = SFBarcodeQRVersion.SFBarcodeQRVersionAuto;
```

- The
`Version`

property allows you to set various types of version for QR code from SFQRVersion enumeration. By default, its value is set as Auto.
