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.
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.

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.

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
Dynamic Web Twain Plugin
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.
