How to Generate QR Codes in .NET and Read Barcodes from Images

Quickly Generate QR Codes in .NET

The .NET barcode API supports generating QR codes with different types of encoding. You can add this functionality to your barcode manipulation applications and further enhance your offerings. Please check the following information and C# coding to quickly and easily generate QR codes using Aspose.BarCode for .NET library:

• Instantiate the BarcodeGenerator class and specify the EncodeType and the input text.
• Set the QR code version and encoding type.
• Generate and save the QR Code image in PNG format.

// Initialize an instance of BarcodeGenerator class
BarcodeGenerator gen = new BarcodeGenerator(EncodeTypes.QR, "Aspose");
gen.Parameters.Barcode.XDimension.Pixels = 4;
// Set Auto version
gen.Parameters.Barcode.QR.QrVersion = QRVersion.Auto;
//Set ForceMicroQR QR encode type
gen.Parameters.Barcode.QR.QrEncodeType = QREncodeType.ForceMicroQR;
gen.Save(dataDir + "QREncodeTypeForceMicroQR.png", BarCodeImageFormat.Png);

Read Barcodes from Images in .NET

Aspose.BarCode for .NET API makes reading barcodes of different symbologies from PNG, JPEG, BMP, GIF, and other image file formats easier. This .NET barcode recognition and generation API supports scanning and reading multiple barcodes from the same image. Please check the following information for more help:

• Load the source barcode image using the BarCodeReader class.
• Call the ReadBarCodes() method to get recognition results in the BarCodeResult class object.
• Loop through the obtained results and display the barcode’s type and text.

// Initialize barcode reader
BarCodeReader reader = new BarCodeReader("C:\\Files\\BarCode\\Sample.png");

// Read the barcode and show the results
foreach(BarCodeResult result in reader.ReadBarCodes()) 
{
    Console.Out.WriteLine("CodeText: " + result.CodeText);
    Console.Out.WriteLine("Symbology type: " + result.CodeType);
}
