This simple how-to example is about how to generate QR code in C++. A QR code is a type of two dimensional barcodes and is very commonly used in different application by C++ developers. In C++ QR code generator application can be developed with few steps and very simple API calls with no dependence on third party API or tool. The developed application can be used in any C++ based application inside MS Windows environment.

Steps to Generate QR Code in C++

1. Add Aspose.Barcode for C++ using NuGet package manager tool in your application
2. Add a reference to Aspose::Barcode and AsposeBarCode::Generation namespaces
3. Include required header files reference in your application
4. Initialize BarcodeGenerator class object to create a QR code by setting QR as encode type
5. Set the QR code text and other parameters
6. Using Save method in C++ generate QR code in PNG image format

In order to develop QR code generator C++ code as specified in above steps can be used. After installing the API package using NuGet and including required header files in application, we will start the process with an instance of BarcodeGenerator class and set the encoding type to QR. You can use other EncodingTypes but in this example we are focusing on QR code. Afterwards, we will set the QR code text and other important parameters like resolution of the QR code. Finally, the QR code will be saved on the disk using save method.

Example to Generate QR Code in C++

In the above code example, we have seen that in order to generate QR code C++ API calls have been used. We can obtain the QR code in different output image formats like PNG, Tiff, JPEG or BMP formats. You can also customize the resolution, back ground colors and also the QR code image width and height using simple C++ code.

In this topic, we have witnessed that to develop a QR code generator C++ based API provides an extremely simple API interface and steps. If you are looking further to enhance your application by adding the generated QR code image in DOCX, refer to the article on how to add Image in DOCX using C++.
