Dynamic Web TWAIN: Does the SDK support creating a scan page in other language than English?

As a SDK, you don't need to worry about the display language of your scan page. By default, all the sample projects of Dynamic Web TWAIN are created in English. However, you can surely create a scan page in own local language as the interface is all about HTML element.

Regarding the built-in error messages of Dynamic Web TWAIN, you can also translate them into your own language in JavaScript. Please click here for the error list of DWT.
