2D Code Generator | 2D Code Creator | Make 2D Barcode

2D barcodes, also called matrix barcodes, store data in both vertical and horizontal directions. This two‑dimensional format holds far more information than traditional 1D barcodes, making it perfect for space‑constrained applications. QR codes (Quick Response codes) are the most common 2D barcodes. Their black‑and‑white squares appear on product labels, restaurant menus, and even street art. A single scan can open a website, show a text message, link to a social profile, or launch an app. This guide provides step‑by‑step instructions for generating 2D barcodes or QR codes with the 2D barcode generator API. Let’s begin.

2D Barcode Generator API

Aspose.Barcode is a popular 2D barcode and QR code generator API that allows you to create and customize various types of 2D barcodes, including QR codes. It is a comprehensive barcode generation and recognition library that enables developers to integrate barcode functionality into their .NET, Java, PHP, C++, Android, Node.js, and Python applications. The API supports over 60 barcode symbologies, including both 1D and 2D barcodes. In the following sections, we will explore the steps to create a QR code for text using the Aspose.Barcode library.

The API allows generating QR Code, Micro QR Code, PDF417, Compact PDF417, Macro PDF417, Micro PDF417, Aztec Code, Data Matrix, DotCode, GS1 Data Matrix, GS1 QR Code, MaxiCode, Swiss QR Code, Han Xin Code, HIBC LIC QR Code

How to create 2D Barcodes or QR Codes?

  1. Download and install the Aspose.Barcode library.
  2. Initialize a new instance of the BarcodeGenerator class.
  3. Specify the text you want to encode in a 2D barcode.
  4. Save the generated code image to a file.

2D Barcode Generator in C#

We can create a 2D barcode and develop a code generator with Aspose.BarCode for .NET by following the steps given below:

  1. Firstly, please either [download the DLL of the API][18] or install the [Aspose.BarCode NuGet package][19] using the following command in the Package Manager Console:
PM> Install-Package Aspose.BarCode
  1. Next, create an instance of the BarcodeGenerator class and set the EncodeTypes.
  2. Then, specify the text to encode.
  3. Optionally, specify code customization options.
  4. Finally, call the save() method to save the generated barcode image at the given file path.

The following code sample shows how to generate a 2D barcode using C#.

2D Code Generator in Java

Similarly, we can create a 2D barcode in Java using Aspose.BarCode for Java by following the steps mentioned above. However, we need to [download the JAR of the API][20] or add the following pom.xml configuration in a Maven‑based Java application.

<repository>
    <id>AsposeJavaAPI</id>
    <name>Aspose Java API</name>
    <url>https://repository.aspose.com/repo/</url>
</repository> 

<dependency>
    <groupId>com.aspose</groupId>
    <artifactId>aspose-barcode</artifactId>
    <version>23.10</version>
</dependency>

The following code sample shows how to create a 2D barcode using Java.

Make a 2D barcode in Python

For creating 2D barcodes or QR codes in Python, we will use Aspose.BarCode for Python via .NET. Follow the steps mentioned earlier, then either [download the Python package][21] or install the API from PyPI using the following pip command:

pip install aspose-barcode-for-python-via-net

The following code sample shows how to create a 2D barcode in Python.
