Creating QR Code with Specified Module Size in .NET WinForms

If you want to print a QR Code with specified module size, you can easily do so by setting both QR Code "X" and "Y" dimensions - bar width & bar height. Here is the C# & VB.NET sample code:

C# Sample Code
VB.NET Sample Code

barcode.X = 3;
barcode.Y = 3;

barcode.X = 3
barcode.Y = 3

Generating QR Code with Specified Version

According to ISO+IEC+18004 QR Code barcode symbology specification, KA.Barcode Generator for .NET WinForms provides the complete set of 40 versions for users to choose from. Copy the demo code below to adjust:

C# Sample Code
VB.NET Sample Code

barcode.QRCodeVersion = QRCodeVersion.V5;

barcode.QRCodeVersion = QRCodeVersion.V5

Adding Quiet Zones on Four Sides for QR Code

It is specified in ISO/IEC standard that for a QR Code symbol, the nominal reflectance value of surrounding margins should be 4X-wide for better readability. For example, if you set QR Code module size (X & Y) to 3 pixels, you should add the code below:

C# Sample Code
VB.NET Sample Code

barcode.LeftMargin =12;
barcode.RightMargin = 12;
barcode.TopMargin = 12;
barcode.BottomMargin = 12;

barcode.LeftMargin =12
barcode.RightMargin = 12
barcode.TopMargin = 12
barcode.BottomMargin = 12
