Dynamsoft Barcode Reader SDK v11, part of the Dynamsoft Capture Vision (DCV) framework, brings a major architectural upgrade for building barcode and QR code scanning applications on desktop, mobile, and web platforms. The v11 C++ SDK introduces the CCaptureVisionRouter as the central orchestration engine. As an enterprise-class C++ barcode and...

Java Development Kit (JDK) does not provide a built-in API for camera access. A common workaround is to use OpenCV with Java bindings (such as JavaCV). However, OpenCV is a fairly large library, which may not be suitable for all applications. In this tutorial, we will demonstrate how to build...

Qt is a cross-platform C++ framework for developing applications with graphical user interfaces (GUIs). In this tutorial, you’ll learn how to create a robust, production-ready Qt C++ barcode scanner integration using Qt 6.7.2, Microsoft Visual C++ (MSVC), C++17, and the Dynamsoft Barcode Reader C++ SDK on Windows. The app decodes...

The font used in the Machine Readable Zone (MRZ) is called OCR-B, which is standardized and globally unified. In the latest version of the Capture Vision SDK, Dynamsoft has released a new deep learning model for MRZ recognition. The model has been trained on a large dataset of MRZ samples...

A virtual scanner is a software-based solution that mimics the functionality of a physical document scanner. It allows developers and testers to simulate scanning operations without requiring actual hardware, making it an essential tool for testing and development. In this tutorial, we’ll explore how to create a virtual scanner device...

Dynamsoft currently provides only a C++ Barcode SDK for macOS. Previously, we built a macOS barcode scanner by combining Swift, Objective-C and C++. Since modern macOS app development primarily relies on Swift, creating a macOS framework that wraps the C++ Barcode SDK with Objective-C++ can streamline the process of calling...

This is the final article in a series on building a lightweight C++ camera library across multiple platforms. We’ve already covered Windows and Linux, and now it’s time to dive into macOS. In this article, we’ll tap into AVFoundation to handle camera capture under the hood and leverage Cocoa for...

In the previous article, we developed a LiteCam library for camera access on Linux. To extend its functionality to Windows, we will leverage the Media Foundation API. This article explores how to use Media Foundation to access the camera on Windows, integrate it with the LiteCam library, and reuse the...

When searching for a camera SDK to develop desktop camera applications on Linux, OpenCV often comes to mind due to its simple APIs for camera access. However, the size of the OpenCV library is big, making it redundant for smaller projects, especially those that only require basic camera functionality. To...

The Machine Readable Zone (MRZ) is a section on passports, IDs, visas, and other travel documents that encodes key personal information, such as the holder’s name, nationality, document number, date of birth, gender, and document expiration date, in a standardized format. In this article, you’ll learn how to use the...

OpenCV is a powerful library capable of handling a wide range of computer vision tasks. However, its comprehensive functionality can result in a large library size, which may be excessive for applications that only require cross-platform camera streaming. In this article, we will demonstrate how to slim down OpenCV to...

In this article, we continue our series on parcel scanning technologies by delving into the world of C++. Building on our previous JavaScript tutorial, we will explore how to implement barcode scanning and OCR text extraction using C++. This guide will cover setting up the development environment, integrating necessary libraries,...

Dynamsoft’s official C++ Barcode SDK provides only command line samples in C++, which are not user-friendly for selecting image files and displaying results. The Win32 API (Windows API) is a core set of application programming interfaces primarily used for developing Windows GUI applications in C and C++. This article will...

Recently, Dynamsoft rolled out C++ Barcode SDK v10.0. This version has been entirely re-written in C++, providing an entirely new suite of APIs for barcode reading. However, if you’re using MinGW(Minimalist GNU for Windows) to code with this SDK, such as integrating it into a Qt project, you may encounter...

When building a TWAIN-compatible application and there is no physical scanner available, you can use a virtual scanner application for development and testing. TWAIN working group has released a TWAIN DS sample on GitHub. In this article, I will detail how to set up the development environment, as well as...

Apple announced new Mac models with Apple M1 chip recently. Although Dynamsoft has not released an Apple Silicon version of Dynamsoft Barcode Reader SDK yet, I am curious how will x86_64 barcode SDK perform under Rosetta 2. In this article, I will build a simple command-line QR Code reader app...
