With 72.19% of Dynamic Web TWAIN customers buying our Plugin Edition to support Chrome and Firefox in their application, the importance of Dynamic Web TWAIN HTML5 Edition is clearer than ever.
- The new solution is implemented with HTML5, which means there is no need to install a plugin/extension for document scanning within Chrome. It brings a new way for data transmission between Web browsers and TWAIN scanners. The user experience is similar and even better in some aspects compared with the original Web TWAIN NPAPI plugin.
- Dynamic Web TWAIN is a TWAIN-based scanning SDK software specifically designed for Web applications on Windows and Mac. All APIs are totally implemented in HTML5. With just a few lines of JavaScript code, you can develop robust applications to scan documents from TWAIN-compatible scanners, edit the scanned images and save them to a file system.
- MaxImagesInBuffer: In the trial version of Dynamic Web TWAIN, the maximum value you can set to the property has been raised from 4 to 1024. Optimized HTTPPostResponseString in Plug-in Edition: You can use HTTPPostResponseString property to get much more detailed info returned from the web server.
As is well known by now, Google is dropping support for NPAPI-based plugins for its Chrome browser. Many NPAPI plugins have already been dropped. A complete phase out is expected by the end of 2014. In addition, Firefox developers are imposing new security features. With the latest version of Firefox Aurora, a user needs to manually enable a plugin on a site to get it to work.
Reasons such as these are why many of our users are upgrading from our Plugin Edition to HTML 5 Edition add-on.
For those that are pondering the switch, it’s important to note the Dynamsoft SDK and add-on working environments are pretty much unchanged. For example, the API list and everything else in the HTML 5 Edition is almost the same as with our Plugin edition. We realized keeping a very similar environment to the Plugin Edition would be important to ease migration.

For end users of the HTML5 version, when they visit a scan page for the first time, this is when embedding of the ‘Web TWAIN for Chrome’ component must occur. It’s at this point the browser will prompt the user to install the service. Outside of any updates, this installation is only necessary once.
After this installation users will be able to perform scanning operations within the browser. They will be able to open local images, edit images, save them to local and network locations, and more.
The migration experience for how end users interact with our HTML5 solution was just as important to us as how developers experience a migration to using our HTML5 SDK add-ons. In a nutshell, we also designed it so your end users experience a straightforward upgrade too.
Still, the technical mechanism of our HTML5 add-on is quite different from the Plugin Edition. Here is an illustration outlining the HTML5 architecture:
While the previous Plugin Edition is a browser extension, the new HTML 5 Edition involves a Task Router Windows service. You can see from the illustration there are three core modules in Dynamic Web TWAIN for Chrome. These are:
- JavaScript Client: this is the Dynamic Web TWAIN JavaScript library. It communicates with the Web TWAIN service. It accepts the operation requests from users and sends them to the Web TWAIN service. It also handles the UI display.
- Task Router Service: This module accepts user operation commands from a JS client and routes the tasks to the Web TWAIN operation module.
- Operation Module: This performs scanning and file operations including load/save files from/to a local disk in a separate process.

Extensibility
Because Dynamic Web TWAIN HTML5 Edition is built using HTML5 technology, it can be easily extended. This includes to IE® and other HTML5-compatible browsers on Windows. And, it includes mobile platforms such as iOS and Android tablets and phones. Here is a simple illustration of how it might work:
As illustrated, all the scanners in your organization will be registered as a resource. When a client – be it a tablet, phone or computer – initiates a scanning request, the user can select which scanner to use, and the Task Router service will communicate with the specified scanner to finish the job. Scanned images will be transferred back to the client through the Task Router service.
Image editing, uploading, loading from local are also supported, as well as the barcode reader SDK add-ons.

Dynamsoft™ has introduced an upgrade to its web TWAIN software development kit (SDK) to specifically address industry plans to phase out browser plugins based on the Netscape Plugin Application Programming Interface (NPAPI). In May Google dropped support of NPAPI plugins for its Chrome browser. The updated Dynamic Web TWAIN SDK will offer a newly developed HTML5 WebSocket plugin add on. It will allow document scanning from within Google® Chrome® browser versions that don’t allow NPAPI plugins.
Dynamic Web Twain Install
The add-on facilitates connections to TWAIN-based scanners in Chrome versions requiring HTML5-based plugins. With 10 years of experience in TWAIN and imaging SDKs, Dynamsoft quickly addressed Google’s retirement of NPAPI-based plugins within Chrome. This continues to ensure customers can develop for any popular browser. The company will also move to address other plugin update requirements in other browsers. The SDK plugin add on currently supports the latest version of Chrome on Windows®. With this new HTML5 component, developers can use it alongside Dynamsoft’s original ActiveX and NPAPI plugins, and Mac® plugin, to easily develop complete cross-browser document scanning modules for HTML5 and NPAPI-based browsers.
Dynamics Plugin Development
“NPAPI-based plugins have long served developers and users to enhance browser capabilities,” said Amy Gu, Vice President of Dynamsoft. “But, these plugins will be phased out by the industry over a relatively quick time. However, NPAPI-based browser use may co-exist alongside newer HTML5-based plugins for some time. Dynamsoft will be there for developers through this transition. We’ll work hard to continue to provide SDKs that allow the creation of cost-effective and easy-to-use document scanning applications within popular browsers, regardless of the plugin type.”

Dynamsoft SDKs enable developers with a simple TWAIN interface so developers need only write just a couple of lines of code in JavaScript. This is instead of taking months to learn the TWAIN standard and then develop an application with hundreds to thousands of lines of code. A finished application gives users key features for document scanning, uploading, editing, and document management within web browsers. The SDKs have built-in support for local image editing and saving options to a variety of formats. Documents can be saved to local or remote databases or other repositories. It supports 32-bit / 64-bit Internet Explorer® (IE), Firefox®, Chrome™, Safari® and Opera™ browsers on Windows and Mac OS X.
