C# Imaging - QR Code Image Generation Tutorial

C# Imaging - QR Code Barcode Add-on Overview

By using this .NET QR Code barcode generator add-on component, developers can create & draw scannable QR Codes on different image files (png, jpeg, gif and bmp) and insert them into common documents like TIFF, PDF, MS Word, Excel and PowerPoint using Visual C#.NET programming code. Following are some barcoding features offered by this .NET QR Code encoder DLL.

Detailed features are listed below:

Written in C# managed code, compatible with .NET Framework 2.0 and above

Generating, writing QR Code bar codes on PNG, JPG, GIF, and BMP image files with specified location

C# tutorial and sample codes to draw, insert QR Codes in PDF, TIFF, MS Word, Excel and PowerPoint

Control QR Code barcode size by setting size related properties

Use C# code to adjust bar code image format, location, resolution, orientation, version, color and more

Compatible with ISO+IEC+18004 QR Code bar code symbology specification

C# Code for Customizing QR Code Barcode Generation

You can easily generator QR Code barcode and save it  to image files/object using this C#.NET barcode generator control. The following steps will show how to create a QR Code type barcode encoding numeric data text "123456789" into the image object with XImage.Barcode.Creator.

Please copy the sample code as follow to generator a QR Code barcode.

private static QRCode CreateBarcode()
        {
            QRCode barcode = new QRCode();// create a Data Matrix barcode
            barcode.Data = "123456789";// encode data into Data Matrix barcode    
            barcode.X = 5.0F;// set module size
            // the minimum value for each margin should be equal to X
            barcode.RightMargin = barcode.LeftMargin = barcode.TopMargin = barcode.BottomMargin = barcode.X;
            barcode.Resolution = 96;// set barcode printing resolution   
            barcode.Rotate = Rotate.Rotate0;// set rotation
            barcode.BarcodeHeight = 200;
            barcode.BarcodeWidth = 200;
            barcode.AutoResize = true;

            //convert barcode to a bitmap and save it to image file
            //Bitmap bmp = barcode.ToImage();
            //bmp.Save(@"C:\barcode.bmp");

            return barcode;
        }

C# Imaging - Draw QR Code on Image File

This C# QR Code barcode generator add-on supports drawing QR Code two-dimensional bar code at any specified location on a target image file. The supported image formats include png, gif, jpeg and bmp. Copy Visual C# sample code below to your .NET imaging application to create and insert a QR Code bar code on a sample png image.

private static void AddBarcodeToImage(QRCode barcode)
        {
            REImage image = new REImage(inputDirectory + "Sample.png");
            barcode.DrawBarcode(image, 150F, 150F);
            image.Save(ImageType.PNG, outputDirectory + "Sample_Barcode.png");
        }

C# Imaging - Create QR Code on Document Page

Apart from generating QR Code on image files, C#.NET barcode creator plug-in of RasterEdge DocImage SDK for .NET can also create QR Code in common document files, like TIFF, PDF, Word, Excel and PowerPoint. Using this C#.NET barcode creating control, you can also customize the location of generated QR Code barcode on target document file.
