Release Notes

The release notes for the current and all past releases can be read here: 📄 Release Notes

Usage / Quick start

You only need five lines of code, to generate and view your first QR code.

QRCodeGenerator qrGenerator = new QRCodeGenerator();
QRCodeData qrCodeData = qrGenerator.CreateQrCode("The text which should be encoded.", QRCodeGenerator.ECCLevel.Q);
QRCode qrCode = new QRCode(qrCodeData);
Bitmap qrCodeImage = qrCode.GetGraphic(20);

Optional parameters and overloads

The GetGraphics-method has some more overloads. The first two enable you to set the color of the QR code graphic. One uses Color-class-types, the other HTML hex color notation.

//Set color by using Color-class types
Bitmap qrCodeImage = qrCode.GetGraphic(20, Color.DarkRed, Color.PaleGreen, true);

//Set color by using HTML hex color notation
Bitmap qrCodeImage = qrCode.GetGraphic(20, "#000ff0", "#0ff000");

The other overload enables you to render a logo/image in the center of the QR code.

Bitmap qrCodeImage = qrCode.GetGraphic(20, Color.Black, Color.White, (Bitmap)Bitmap.FromFile("C:\\myimage.png"));

There are a plenty of other options. So feel free to read more on that in our wiki: Wiki: How to use QRCoder
