Dynamsoft recently released Barcode Reader SDK v5.0 for Windows. You can think of it as a brand new product because a large number of APIs and data structures are redefined. If you have downloaded DBR v5.0 and tried to build Node.js barcode addon with it, you have to spend some time modifying the sample code that written for DBR v4.x. In this article, I will share the difference between DBR v4.x and DBR v5.0, as well as how to update the current code to fit the new interfaces.
Dynamsoft has deployed a REST web service for barcode detection. This post shares how to call the service by sending HTTP POST request using Golang.
A few months ago, Google announced a new operating system named Fuchsia. It was my first time to hear about Dart, which is the primary programming language for Fuchsia. Dart is a programming language designed by Google. It is used to build the web (Dart webdev), mobile (Flutter) and server (Dart VM) applications. In this article, I will share how to write my first Dart console application with Dynamsoft barcode RESTful web service.
When developing an Android project with Xamarin, I didn’t get any trouble. However, it is totally a different experience when building an iOS app with Xamarin – it is more complicated. In this article, I will share my experience of binding DynamsoftBarcodeReader.framework using Xamarin.
Previously, I wrote an article Raspberry Pi Barcode Scanner with Webcam and Python illustrating how to build a simple barcode scanner using Dynamsoft Barcode Reader SDK and OpenCV from scratch. The method decodeFile() was used for detecting barcodes from an image file. To use the API, you have to firstly write image buffer that obtained by OpenCV API to a file. Because the I/O operation takes too much time, this API is not suitable for real-time barcode detection from webcam video stream. Considering this scenario, I have added a new Python API decodeBuffer(). In this article, I will illustrate how to create and use the new API.
C# is the preferred programming language for developing Windows applications. However, Microsoft only provides .NET camera APIs for UWP applications. If you plan to write a classic Windows desktop application using a webcam, it will be complicated to create a C/C++ wrapper for DirectShow Win32 APIs. Dynamic .NET TWAIN is an SDK that supports programming for both scanner and webcam. In this article, you will see how easy to build a webcam application with the SDK. In addition, you can learn how to detect and recognize barcodes from the video stream with Dynamsoft Barcode Reader SDK.
