##Usage

After referencing the QRCoder.dll in your project, you only need three lines of code, to generate and view your first QR code.

QRCodeGenerator qrGenerator = new QRCodeGenerator();
QRCodeGenerator.QRCode qrCode = qrGenerator.CreateQrCode(textBoxQRCode.Text, QRCodeGenerator.ECCLevel.Q);
pictureBoxQRCode.BackgroundImage = qrCode.GetGraphic(20);

The GetGraphics-method has 2 more overloads. Both 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
pictureBoxQRCode.BackgroundImage = qrCode.GetGraphic(20, Color.DarkRed, Color.PaleGreen);

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