QR Code Barcode Fonts

The QR Code (Quick Response) barcode is a 2-dimensional barcode consisting of black square patterns on a white background. The barcode is capable of storing more information than a conventional barcode. It is developed by Denso-Wave in Japan and is one of the more popular 2-dimensional barcodes. Another reason for this barcode popularity is because it is adopted by many mobile or smartphone applications for linking physical world objects to a web URL (Uniform Resource Locator).

ConnectCode QR Code Barcode Font

This is a professional True Type (TTF) barcode font that is used to create a QR Code barcode by selecting a font in your favorite text editor. The package includes a standalone Encoder, a .Net Dynamic Link Library (DLL), true type font for creating a QR Code barcode that strictly adheres to industry specifications.

Data Compaction

The QR Code can pack a large amount of data using the various compaction methods. Each of the compaction methods is optimized for a specific type of data. For example, the Numeric method is optimized for numbers. The ConnectCode Encoder automatically scans through the data and detects the most optimized compaction method. On top of that, it also switches among the different compaction methods if one method cannot fully encode the data.

Numeric - Optimized for numbers.
Alphanumeric - Optimized for numbers and alphabets. This compaction method is less optimized than Numeric.
Binary - Optimized for any 8-bit binary data.
Kanji - Optimized for Kanji data.

Parameters of the QR Code Barcode

The following sections detail the different configurable parameters of the QR Code barcode. If you are new to this barcode, it is recommended that you use the default or automatic settings mentioned below.

Error Correction

QR Code uses the Reed-Solomon error correction technique. This allows the barcode to be partially damaged without causing any loss of data. There are four different levels of error correction that can be chosen. The higher the level, the more resilient the barcode is to withstand damage. However, the drawback is that more data codewords in the barcode are needed to store the error correction codewords instead of the actual data.

Level L - 7% of codewords can be recovered
Level M - 15% of codewords can be recovered
Level Q - 25% of codewords can be recovered
Level H - 30% of codewords can be recovered

Mask

QR Code's reliability can be improved by a method called masking. Masking regularizes the distribution of the black square patterns. Different types of masking patterns, according to the specifications, are supported by the ConnectCode QR Code. The default automatic masking option is recommended if you do not want to delve into the barcode's technical implementation.

Mask 0 - Mask Pattern 0
Mask 1 - Mask Pattern 1
Mask 2 - Mask Pattern 2
Mask 3 - Mask Pattern 3
Mask 4 - Mask Pattern 4
Mask 5 - Mask Pattern 5
Mask 6 - Mask Pattern 6
Mask 7 - Mask Pattern 7
Auto - Automatic Masking

QR Code Barcode Fonts

The following is the description of the QR Code barcode font used by the Encoder or .NET DLL.

Font Name	Description	Recommended Sizes
CCodeQR	Standard QR Code Barcode Font. (CCodeQR_Trial for the Trial version)	Font Size 2..64

Note: You may see spaces between multiple Rows when you use the QR Code barcode fonts in certain font sizes. The spaces can be easily removed by increasing or decreasing the font size by 1 point.

Font Encoder

The QR Code Barcode Font package in ConnectCode comes bundled with a Font Encoder that allows you quickly and easily encode the barcode. This is useful if you like to encode a single barcode and paste it into your brochure, on the packaging, or product items. The Encoder supports all parameters, as described in the sections above.

The Error Level and Mask parameters are supported (see the previous section for detailed description).

The Font Name and Font Size in the "Output" section can be adjusted after the QR Code barcode is created. This allows the height and the size of the barcode to be changed after the barcode is created.

The "Show As Text" option allows you to see the text output of the barcode in a regular text font. The "Copy Barcode" button allows the barcode to be copied and pasted onto other applications easily.

.NET SDK

A .NET Barcode SDK is also bundled in the ConnectCode QR Code Barcode Font package. This SDK can be bundled in your applications if you purchase the necessary distribution licenses.

Library Name : QRCode.dll

Namespace : ConnectCode.BarcodeFonts2D

Class Name : QRCode
Requirements : .NET 2.0 and onwards

Constructors and Functions

QR(String data, String errorcorrectionlevel, int mask);

This is the constructor for the QR barcode. It is used for initializing the QR barcode.

data : The data input string to be encoded as a barcode.
errorcorrectionlevel : The Error Correction Level "L", "M", "Q" or "H".
mask : Mask Pattern. Any number from 0..7 or 8 for Auto.

String Encode();

This function encodes the barcode based on the parameters specified in the constructor. The result will be returned as a string.

int LengthExceeded();

The Encode() function may return an empty output string due to invalid inputs or the length of the data exceeded the length specified by the QR Code specifications. After the Encode() function, a call to this function allows you to determine whether the data length has exceeded.

Sample Usage (C#)

Using ConnectCode.BarcodeFonts2D;
.
.
.
QR barcode = new QR("12345678","M",0);
String result = barcode.Encode();
Font font = new Font("CCodeQR", 8);
//private System.Windows.Forms.RichTextBox richTextBox1;
richTextBox1.Text = outputstr; 
richTextBox1.SelectAll();
richTextBox1.SelectionFont = font;

For Production Server or Enterprise Installation
Install QR Code Barcode Fonts manually or on Windows Server

Note - Users of QR Code v1.0 - 2.8, please contact us for your free upgrade.

Overview of what the installer does

Install the Barcode Font Encoder on your system.
Install .NET DLL and help file on your system.
Install True Type fonts on to your system with your permission. During installation, you will be prompted whether to allow the installer to copy the fonts into your "C:\Windows\Fonts" folder automatically.

The QR Code Encoder requires the Microsoft .NET Framework (2.0 or onwards) to run. If the software fails to launch, you may want to install the latest .NET Framework from the following :

msdn.microsoft.com/en-us/netframework/aa569263.aspx

Uninstall Instructions

On your system, go to "C:\Program Files (x86)\ConnectCodeQRCodeTrial" or the location where the software is installed.
Double click on Uninstall.exe.
Click on the "Yes" button followed by the "Uninstall" button. This will uninstall all the fonts and software on your system.

Windows installation notes

1. It is recommended to close all other applications before proceeding with the installation. The reason is because the installer set up the barcode fonts by copying the files into the Windows fonts (C:\Windows\Fonts) directory. Some software applications may be using Windows fonts, and this may block the Copy process. If you are in the middle of the installation process and notice that the installation has stalled, shut down other applications to let the installation resume.

2. If the QR Code Barcode appears as text characters in the Encoder, try rebooting your System for the fonts to take effect.

Windows Server installation notes

For installation on Windows Server 2003-2022, we recommend using the zip file. If you are using the EXE Installer, please choose "No" when prompted to Setup Fonts Automatically.

How do I install the QR Code barcode fonts on my PC or Windows Server manually?

Launch Windows Explorer.
If you have installed using the EXE installer, go to the C:\Program Files (x86)\ConnectCodeQRCodeTrial folder. If you are using the ZIP file, go to the unzipped QRCodeTrial folder.
In the folder, right click on the True Type barcode fonts and select the Install option.
Once the barcode fonts are installed, they can be used by other applications such as Microsoft Excel, Microsoft Word or our own Barcode Fonts Encoder shown below.

QR Code Barcode Fonts Encoder

The installer package and zipped file contains a classic QR Code Barcode Fonts Encoder that works on Windows 7 to Windows 11.

A modern Windows 10 - 11 Barcode Software Encoder is also available from Microsoft Store. This encoder automatically detects ConnectCode's QR Code barcode font and unlocked the necessary capabilities.
