In this article, we will explain how to convert a barcode to image in SfBarcodeGenarator using RepaintBoundary. Generating barcodes is a common feature in mobile applications, but converting them into images can be useful when you need to save the barcode for offline use or display it outside of the barcode widget. The RepaintBoundary widget in Flutter provides an easy way to capture any widget as an image, and by combining it with SfBarcodeGenarator, we can create, capture, and display a barcode as an image within the app. The following steps will explain how to capture and convert the barcode into an image using Flutter’s RenderRepaintBoundary and display it on a new screen. Step 1: Create a GlobalKey for RepaintBoundary, which is used to uniquely identify the widget that needs to be captured as an image. final GlobalKey _globalKey = GlobalKey(); Step 2: Place the SfBarcodeGenarator inside a RepaintBoundary, allowing it to be rendered as an image. @override Widget build(BuildContext context) { Column( mainAxisAlignment: MainAxisAlignment.center, children: [ SizedBox( child: RepaintBoundary( key: _globalKey, child: SfBarcodeGenerator(value: 'http://www.syncfusion.com'), ), ), ElevatedButton( onPressed: _renderBarcodeImage, child: const Text('Barcode to image'), ), ], ); } Step 3: Create a function to capture the barcode as an image, using RenderRepaintBoundary to convert the widget’s content into the specified format, such as PNG. Future<void> _renderBarcodeImage() async { final RenderRepaintBoundary boundary = _globalKey.currentContext?.findRenderObject() as RenderRepaintBoundary; final ui.Image data = await boundary.toImage(pixelRatio: 3.0); final bytes = await data.toByteData(format: ui.ImageByteFormat.png); await Navigator.of(context).push( MaterialPageRoute( builder: (BuildContext context) { return Scaffold( body: Center( child: Container( color: Colors.white, child: Image.memory(bytes!.buffer.asUint8List()), ), ), ); }, ), ); } Now, convert the barcode to an image in Flutter using the SfBarcodeGenarator have been implemented as shown below.

The Syncfusion Essential JS Barcode control is used to render one-dimension and two-dimension barcodes in webpage. Barcode provides a simple and inexpensive method of encoding text information that can be easily read by electronic readers. Using this control, you can get an image from barcode. Steps to get an image from barcode programmatically: Add div container for barcode rendering. <div id="barcode"></div> Use the following code to get an image from barcode. This can be achieved by setting ID to the barcode canvas manually then convert it to image. <script type="text/javascript"> var barcodeCtrl; $(function () { $("#barcode").ejBarcode({ text: "HTTP://WWW.SYNCFUSION.COM", symbologyType: "qrbarcode", xDimension: 12, }); barcodeCtrl = $("#barcode").data("ejBarcode"); }); function Download(link, canvasId, filename){ link.href = document.querySelector(canvasId).toDataURL(); link.download = filename; } document.getElementById('download').addEventListener('click', function () { Download(this, '#barcode canvas', 'Barcode.png'); }, false); </script> By executing the program, you will get the PNG image as follows.

How to choose right color combination to the Barcode? While customizing the barcode main thing to consider color combinations, which is important to choose right color combination to the barcode for recognizing with scanner. This article explains you about how to choose right color combination to the Barcode in Xamarin Android. Barcode color can be customized by the DarkBarBrush and LightBarBrush properties. It’s important to use light colors for the background and dark colors for the barcode. Right color combination Below are color combinations are scan-able. The best contrast is obtained when the background reflects all the light and the bars reflect none which can that can work for barcode labels. Dark and light color combination will always work with all type of Barcodes. Black on White Blue on White Green on White Black on Yellow Blue on Yellow Green on Yellow Black on Red Blue on Red Green on Red Wrong Color Combination If the background and bar colors, both are too light or too dark, the scanner won’t be able to read the barcode label. Below are color combinations are Non scan-able. Red on White Yellow on White Light Brown on White Black on Yellow Black on Green Black on Blue Red on Blue Green on Blue Brown on Blue
How to choose the right barcode for your application? Barcode supports different variants of symbologies in both One dimensional as well as in Two dimensional, which can be used in various applications. This article explains you about choosing the right barcode for your application. 1D Barcode: One dimensional Barcode is a linear Barcode, The bars and spaces signified for each symbol in one dimensional Barcodes are grouped in such a way to represent a specific ASCII character. Which has commonly used on consumer goods, use a series of variable-width lines and spaces to encode data. Linear barcodes hold just a few dozen characters, and generally get physically longer as more data is added. 2D Barcode: Two dimensional Barcode is a way to represent information by using two-dimensional approach. It is similar to one dimensional Barcode, but can represent more data per unit area. Two dimensional Barcode, like Data Matrix and QR Code, use patterns of squares, hexagons, dots, and other shapes to encode data. They can be much smaller while holding more data (hundreds of characters) than 1D codes. Data is encoded based on both the vertical and horizontal arrangement of the pattern, thus it is read in two dimensions.
