Barcode Customization in WPF Barcode (SfBarcode)

9 Jul 20261 minute to read

Overview

The color of the barcode can be customized by modifying the DarkBarBrush and LightBarBrush properties of the barcode control. The DarkBarBrush represents the color of the dark bar (Black color usually) and the LightBarBrush represents the color of the gap between two adjacent dark bars (White color usually).

Customizing the barcode colors

The following code example shows how to set the dark and light bar colors.

  • XAML
    • <sync:SfBarcode x:Name="barcode" Text="82698640929" DarkBarBrush="Red" LightBarBrush="Blue" Symbology="Code128"/>

    The following images illustrate the barcode rendered with different color combinations.

    WPF-Barcode-Red-Color-Combination

    Barcode color combinations – Red

    WPF-Barcode-Blue-Color-Combination

    Barcode color combinations – Blue

    Limitations

    NOTE

    The DarkBarBrush and LightBarBrush customizations are applicable only for one-dimensional barcodes. For a barcode symbol to be recognized by a scanner, there must be adequate contrast between the dark bars and the light spaces. Additionally, not all barcode scanners support colored barcodes.
