Ravishankar N · Answer

Hi Krishna vala, Use qrlib library is really fast to configure and the API documentation is easy to understand Download the qrlib from the below link https://github.com/t0k4rt/phpqrcode/blob/master/qrlib.php Usage include ( '../lib/full/qrlib.php' ); // outputs image directly into browser, as PNG stream QRcode::png( 'PHP QR Code :)' ) ?>

Hello Krishna, You can use LEADTOOLS .NET BarcodeWriter class to create a web (WCF) service that receives images data, use the WriteBarcode method (Leadtools.Barcode Namespace > BarcodeWriter Class) to write QR barcodes by passing the BarcodeSymbology.QR flag to the WriteBarcode method, and then return back the image with the barcode in any image or data format you want. You can create a C# Web-Service and use the following LEADTOOLS C# code to write QR barcodes on your images: // Create a QR code using the text BarcodeEngine engine = new BarcodeEngine(); int resolution = 300; using (RasterImage image = RasterImage.Create(( int )(8.5 * resolution), ( int )(11.0 * resolution), 1, resolution, RasterColor.FromKnownColor(RasterKnownColor.White))) { BarcodeWriter writer = engine.Writer; QRBarcodeData data = BarcodeData.CreateDefaultBarcodeData(BarcodeSymbology.QR) as QRBarcodeData; data.Bounds = new LeadRect(0, 0, image.ImageWidth, image.ImageHeight); QRBarcodeWriteOptions writeOptions = writer.GetDefaultOptions(data.Symbology) as QRBarcodeWriteOptions; writeOptions.XModule = 30; writeOptions.HorizontalAlignment = BarcodeAlignment.Near; writeOptions.VerticalAlignment = BarcodeAlignment.Near; data.Value = recognizedCharacters; writer.CalculateBarcodeDataBounds( new LeadRect(0, 0, image.ImageWidth, image.ImageHeight), image.XResolution, image.YResolution, data, writeOptions); writer.WriteBarcode(image, data, writeOptions); } You can find more details in the following online help topics: https://www.leadtools.com/help/leadtools/v20/dh/ba/barcodewriter.html https://www.leadtools.com/help/leadtools/v20/dh/ba/barcodesymbology.html
