C# Sample code
BarCode qrcode = new BarCode();
qrcode.Symbology = KeepAutomation.Barcode.Symbology.QRCode;
//Select a QR Code supported data mode according to your code:
//AlphaNumeric: for 0 - 9, upper case letters A - Z, and nine punctuation characters space, $ % * + - . / :
//Byte data: for (ISO/IEC 8859-1) encoding characters at 8 bits per character
//Kanji Characters (JIS)
//Numeric: for digits 0 - 9
qrcode.QRCodeDataMode = QRCodeDataMode.Auto;
//Input your QR Code encoding data:
qrcode.CodeToEncode = "C#QRCodeGenerator";
// Unit of measure, pixel, cm and inch supported.
qrcode.BarcodeUnit = BarcodeUnit.Pixel;
// QR Code image resolution in dpi
qrcode.DPI = 72;
// QR Code bar module width (X dimention)
qrcode.X = 3;
// QR Code bar module height (Y dimention), Y=X
qrcode.Y = 3;
// QR Code image left margin size, the minimum value is 4X.
qrcode.LeftMargin = 12;
// Image right margin size, minimum value is 4X.
qrcode.RightMargin = 12;
// Image top margin size, minimum value is 4X.
qrcode.TopMargin = 12;
// Image bottom margin size, minimum value is 4X.
qrcode.BottomMargin = 12;
// QR Code orientation, 90, 180, 270 degrees supported.
qrcode.Orientation = KeepAutomation.Barcode.Orientation.Degree0;
// QR Code barcode version, valid from V1-V40
qrcode.QRCodeVersion = QRCodeVersion.V5;
// QR Code barcode Error Correction Lever, supporting H, L, M, Q.
qrcode.QRCodeECL = QRCodeECL.H;
// QR Code image formats, supporting Png, Jpeg, Gif, Tiff, Bmp, etc.
qrcode.ImageFormat = ImageFormat.Png;
// Generate QR Code barcodes in image format GIF
