QR Code, also known as Denso Barcode, QRCode, Quick Response Code, is a kind of 2D (two dimensional) barcode widely used today.

C# QR Code generator library supports creating standard QR Code, defined by ISO / IEC 18004. C# QR Code generator is easy to install and use for generating QR Code in C# development. Various images setting properties, such as image formats (tiff, bmp, png, jpg, svg and eps), image resolution, image rotation (0, 90, 180, 270) and image colors (background color, forecolor) are available for your programming.

OnBarcode C# Barcode Generator is designed to generate, create QR Code and other linear & 2d barcodes in .NET projects (.NET 8, 7, 6, .NET Core, and .NET Framework 4.x, 3.x)


C#.NET QR Code Image Format Setting

C# .NET QR Code image format setting allows 5 image formats (TIFF, BMP, PNG, GIF and JPEG) in the QR Code generation procedure in C# programming.

Setting PNG image format to generate QR Code images in C#.NET Class & console application

QRCode qrcode = new QRCode();

qrcode.Data = "BARCODE-IMAGE";

qrcode.Format = ImageFormat.Png;

qrcode.drawBarcode("c:\QR Code.png");

Setting JPEG format to create QR Code images in C# ASP.NET web projects

QRCode qrcode = new QRCode();

qrcode.Data = "IMAGE-FORMAT";

qrcode.Format = ImageFormat.Jpeg;

qrcode.drawBarcode("c:\QR Code.jpeg");

Setting GIF format to print QR Code images in C#.NET Winforms programming

QRCode qrcode = new QRCode();

qrcode.Data = "QRCODE-FORMAT";

qrcode.Format = ImageFormat.Gif;

qrcode.drawBarcode("c:\QR Code.gif");

Setting TIFF format to draw QR Code in SQL Server Reporting Service (SSRS) & Crystal Reports

QRCode qrcode = new QRCode();

qrcode.Data = "ONBARCODE-QRCODE";

qrcode.Format = ImageFormat.Tiff;

qrcode.drawBarcode("c:\QR Code.tiff");

Setting BMP format to output QR Code in C# class

QRCode qrcode = new QRCode();

qrcode.Data = ".NET-QRCODE";

qrcode.Format = ImageFormat.Bmp;

qrcode.drawBarcode("c:\QR Code.bmp");


C#.NET QR Code Image Rotation Setting

C# .NET QR Code image rotation setting supports rotating the generated QR Code image with 0, 90, 180, 270 degrees in C# projects:

QRCode qrcode = new QRCode();

qrcode.Data = ".NET";

qrcode.Rotate = Rotate.Rotate90;


C#.NET QR Code Image Resolution Setting

C# .NET QR Code image resolution setting allows setting the resolution for the created image in C# programming:

QRCode qrcode = new QRCode();

qrcode.Data = "ONBARCODE";

qrcode.Resolution = 220;


C#.NET QR Code Image Color Setting

C# .NET QR Code image color can be easily integrated with changing the text color, background color and bar color when generating QR Code in C# class:

QRCode qrcode = new QRCode();

qrcode.Data = "QRCODE";

qrcode.BackColor = Color.White;

qrcode.ForeColor = Color.Black;

qrcode.TextColor = Color.Black;


C#.NET QR Code Bar Alignment Setting

C# .NET QR Code supports Bar Alignment setting property:

QRCode qrcode = new QRCode();

qrcode.Data = "45646";


qrcode.BarAlignment = AlignmentHori.Center;

When the set image width is larger than the minimum image width, Bar Alignment property can set the extra space on the left, center and right side.
