When discussing cross-platform development with Flutter, many developers immediately think of mobile app development. As a result, most Flutter plugins only support Android and iOS. However, Flutter is capable of much more than just mobile development—it also supports desktop and web platforms. Imagine building a cross-platform barcode scanner app from...

While Flutter supports six plaforms — Windows, Linux, macOS, Android, iOS and web — the official Flutter camera plugin is limited to just three: Android, iOS, and web. The development pace for the official plugin has been sluggish, with no clear roadmap for desktop support. As a result, creating a...

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...

In the previous article, we demonstrated how to build a Python camera SDK based on the litecam C++ SDK. In this article, we will integrate the C++ camera library into a Node.js addon, enabling developers to capture webcam frames and perform further image processing using server-side JavaScript. This article is...

Now that the lightweight C++ camera SDK is complete for Windows, Linux and macOS, we can integrate it into other high-level programming languages. In this article, we will explore how to build a Python camera SDK based on the C++ camera library and use it for multi-barcode scanning with the...

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...

In the previous tutorial, we explored how to build a SwiftUI barcode scanner app for macOS using the Dynamsoft Capture Vision C++ SDK. Since SwiftUI is a cross-platform framework supporting both macOS and iOS, and the Dynamsoft Capture Vision SDK provides a Swift Package Manager (SPM) for iOS, it is...

Developing a barcode scanner app for macOS comes with unique challenges, particularly due to the limited availability of barcode SDKs specifically designed for the platform. Fortunately, the Dynamsoft Capture Vision SDK provides a powerful and reliable solution, enabling developers to easily build barcode, MRZ, and document scanners using Python (powered...

Blazor is a powerful framework by Microsoft that enables developers to build interactive web applications using C# instead of JavaScript, bringing the full power of .NET to the browser. While Blazor allows you to write most of your web app in C#, calling existing JavaScript APIs remains an inevitable part...

According to the American Association of Motor Vehicle Administrators (AAMVA) specification, US driver’s licenses store personal information using the PDF417 barcode symbology. Google’s Mobile Vision APIs can recognize PDF417 barcodes and extract driver’s license data, while the combination of Dynamsoft Barcode Reader and Dynamsoft Code Parser achieves the same goal....

Recently, Dynamsoft released a new .NET MAUI Barcode SDK for building barcode scanning applications on Android and iOS. In this tutorial, we will use Visual Studio Code to create a .NET MAUI Barcode Scanner from scratch. Our application will decode barcodes and QR codes from both image files and camera...

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...

Many open-source JavaScript libraries for reading barcodes and QR codes exist, yet few are suited for enterprise use due to a lack of long-term updates and maintenance roadmaps. Additionally, the performance of pure JavaScript often falls short. For those prioritizing performance, WebAssembly serves as a superior alternative to pure JavaScript...

SwiftUI is a robust UI framework designed for constructing native applications across all Apple platforms. This article will guide you through developing an iOS QR code scanner utilizing SwiftUI, Dynamsoft Camera Enhancer and Dynamsoft Barcode Reader on an M1 Mac mini. This article is Part 1 in a 6-Part Series....

Starting with version 10, the Dynamsoft Barcode Reader SDK has been entirely rewritten in C++, providing exclusively C++ APIs. This marks a significant departure from version 9.x, which offered both C and C++ APIs, rendering our Go module designed for version 9.x incompatible with version 10. The incompatibility arises because...

Raspberry Pi is a versatile tool, especially in industrial settings. Imagine transforming it into a barcode scanner using just a camera. This guide is tailored for developers eager to craft Node.js barcode reader apps for IoT gadgets. Dive in to explore the power of Dynamsoft’s barcode SDK for ARM, and...

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.
