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:
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
From this C#.NET QR Code generating tutorial page, you can get a few C# samples for QR Code barcoding.

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.
// invoke this only once at the beginning of your code WorkRegistry.Reset();
// create REImage on which you want to draw the barcode REImage reImage = new REImage("c:/Sample.png");
QRCode barcode = new QRCode();// create a QR Code barcode barcode.Data = "123456789asdq";// input encodable data barcode.X = 20.0F;// set module size barcode.RightMargin = barcode.LeftMargin = barcode.TopMargin = barcode.BottomMargin = 80; // margins on four sides of QR Code should be 4X barcode.Resolution = 96;// set QR Code barcode printing resolution barcode.Rotate = Rotate.Rotate0;// set rotation
barcode.DrawBarcode(reImage, 0, 0);// draw barcode on REImage with location x and y
reImage.Save(ImageType.PNG, @"c:/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.
Generate QR Code on C# PDF Page
PDFDocument doc = new PDFDocument("c:/Sample.pdf"); PDFPage page = (PDFPage)doc.GetPage(0);
QRCode barcode = new QRCode();// create a QR Code barcode barcode.Data = "123456789asdq";// input encodable data barcode.X = 20.0F;// set module size barcode.RightMargin = barcode.LeftMargin = barcode.TopMargin = barcode.BottomMargin = 80; // margins on four sides of QR Code should be 4X barcode.Resolution = 96;// set QR Code barcode printing resolution barcode.Rotate = Rotate.Rotate0;// set rotation
// add this barcode image to this page REImage barcodeImage = barcode.ToImage(); page.AddImage(barcodeImage, new System.Drawing.PointF(100f, 100f));
// save the changes doc.Save(@"c:/barcode.pdf");
Create QR Code on C# TIFF File
// load TIFF document. You can also load document like PDF, Word, Excel & PPT TIFFDocument tiff = new TIFFDocument(@"c:\sample.tiff");
// get the first page BasePage page = tiff.GetPage(0);
QRCode barcode = new QRCode();// create a QR Code barcode barcode.Data = "123456789asdq";// input encodable data barcode.X = 20.0F;// set module size barcode.RightMargin = barcode.LeftMargin = barcode.TopMargin = barcode.BottomMargin = 80; // margins on four sides of QR Code should be 4X barcode.Resolution = 96;// set QR Code barcode printing resolution barcode.Rotate = Rotate.Rotate0;// set rotation
// add barcode image to the first page REImage barcodeImage = barcode.ToImage(); page.AddImage(barcodeImage, new System.Drawing.PointF(100f, 100f));
// save changes to TIFF document tiff.Save(@"c:\barcode.tiff");
Draw QR Code on C# Word Document
// construct an DOCXDocument DOCXDocument doc = new DOCXDocument(@"c:/Sample.docx");
// get the first page BasePage page = doc.GetPage(0);
QRCode barcode = new QRCode();// create a QR Code barcode barcode.Data = "123456789asdq";// input encodable data barcode.X = 20.0F;// set module size barcode.RightMargin = barcode.LeftMargin = barcode.TopMargin = barcode.BottomMargin = 80; // margins on four sides of QR Code should be 4X barcode.Resolution = 96;// set QR Code barcode printing resolution barcode.Rotate = Rotate.Rotate0;// set rotation
// add barcode image to the first page REImage barcodeImage = barcode.ToImage(); page.AddImage(barcodeImage, new System.Drawing.PointF(100f, 100f));
// save changes to the file doc.Save(@"c:\barcode.docx");
Generate QR Code on C# Excel Sheet
// construct an XLSXDocument XLSXDocument doc = new XLSXDocument(@"c:/Sample.xlsx");
// get the first page BasePage page = doc.GetPage(0);
QRCode barcode = new QRCode();// create a QR Code barcode barcode.Data = "123456789asdq";// input encodable data barcode.X = 20.0F;// set module size barcode.RightMargin = barcode.LeftMargin = barcode.TopMargin = barcode.BottomMargin = 80; // margins on four sides of QR Code should be 4X barcode.Resolution = 96;// set QR Code barcode printing resolution barcode.Rotate = Rotate.Rotate0;// set rotation
// add barcode image to the first page REImage barcodeImage = barcode.ToImage(); page.AddImage(barcodeImage, new System.Drawing.PointF(100f, 100f));
// save changes to the file doc.Save(@"c:\barcode.xlsx");
Draw QR Code Barcode on C# PowerPoint Slide
// construct an PPTXDocument PPTXDocument doc = new PPTXDocument(@"c:/Sample.pptx");
// get the first page BasePage page = doc.GetPage(0);
QRCode barcode = new QRCode();// create a QR Code barcode barcode.Data = "123456789asdq";// input encodable data barcode.X = 20.0F;// set module size barcode.RightMargin = barcode.LeftMargin = barcode.TopMargin = barcode.BottomMargin = 80; // margins on four sides of QR Code should be 4X barcode.Resolution = 96;// set QR Code barcode printing resolution barcode.Rotate = Rotate.Rotate0;// set rotation
// add barcode image to the first page REImage barcodeImage = barcode.ToImage(); page.AddImage(barcodeImage, new System.Drawing.PointF(100f, 100f));
// save changes to the file doc.Save(@"c:\barcode.pptx");

Left Margin: The white space by the left side of QR Code barcode image. Default value is 0 pixel. Note that, in order to create a valid QR Code for scanning, please set the Left Margin to a minimum of 4X. The same goes for Right Margin, Top Margin and Bottom Margin.
FNC1: This is a Boolean value. You can enable it to create a GS1-compatible QR Code bar code image.
Data Mode: Select according to your data type. Kanji is used to encode Japanese character Shift JIS system based JIS X 0208. Auto Mode is recommended for automation data type selecting.
Structure Append: A functionality to encode files of data continuously in up to 16 QR Code symbols.
Version: QR Code 2005 version varies from V1 to V40, starting form 21x21 modules, increasing in steps of 4 modules per side.
C# Imaging - Generate Customized QR Code Using C# Code
This C#.NET QR Code barcode generator add-on makes it quite easy for you to generate a desired QR Code barcode image. Following C# Code can be used to generate a customized QR Code on a png image file in Visual C#.NET class application.
// invoke this only once at the beginning of your code WorkRegistry.Reset();
// create REImage on which you want to draw the barcode REImage reImage = new REImage("c:/Sample.png");
QRCode barcode = new QRCode();// create a QR Code barcode barcode.Data = "123456789asdq";// input encodable data
// QR Code size related settings barcode.UOM = RasterEdge.Imaging.Barcode.Creator.UnitOfMeasure.PIXEL; barcode.X = 5.0F; barcode.BarcodeHeight = 90; barcode.BarcodeWidth = 90; barcode.BottomMargin = 20;// margins on four sides of QR Code should be 4X barcode.TopMargin = 20; barcode.LeftMargin = 20; barcode.RightMargin = 20; barcode.AutoResize = false;
