While using Salesforce, your management system can conveniently extend new functionalities by installing apps from Salesforce AppExchange – the Salesforce store. How can you build a Salesforce app by yourself? In this article, I will share how to create a barcode reader app for Salesforce from scratch.

Read moreHow to Build Web Barcode Reader with Blazor WebAssembly
Blazor is a web framework developed by Microsoft. It enables developers to create web apps using C# and HTML. However, calling existing JavaScript APIs is inevitable while developing a Blazor project. This article will help web developers who want to build web barcode reader apps using Blazor WebAssembly and Dynamsoft JavaScript Barcode SDK.
Read moreHow to Make Dynamic Web TWAIN Work with Polymer Shadow DOM
In the past, Dynamic Web TWAIN was tightly correlated with HTML elements. It only allowed developers to use HTML element ID to initialize the image container. In the meantime, shadow DOM elements were not supported, which failed Polymer projects. Starting from the latest version 16.1, the SDK has a lower coupling. Developers can use either HTML element ID or HTML element object to initialize a Dynamic Web TWAIN object. In this article, I will share how to integrate Dynamic Web TWAIN SDK to a Polymer project for scanning documents in web browsers.
Read moreHow to Use WebGL to Accelerate Web Barcode Decoding Speed
Generally, while doing barcode detection, we pass color images encoded in RGB or YUV to some barcode decoding APIs, in which the image data will be converted from color to grayscale and then from grayscale to binary. Operating pixels takes much CPU time. To accelerate image processing, we can utilize GPU. Dynamsoft JavaScript barcode SDK is powerful for developing web barcode scanning apps, but it is designed for CPU only so far. In this article, I will show you how to use WebGL to convert color image to grayscale image in order to reduce the total CPU time cost when reading barcodes from camera video stream in web apps.
Read moreInsight Into Dynamsoft Barcode SDK Decoding Performance
Many enterprises like to use Dynamsoft Barcode Reader SDK due to its flexible parameter configuration and powerful decoding capability for multiple barcodes. In this article, let’s take a glimpse of the barcode SDK template and the possible way to optimize the decoding performance from a developer’s angle.
