Project Deployment and End-user Installation

What does the Dynamsoft Service do on the end-user machine?

Dynamsoft Service is required for the Desktop Service Edition of Dynamic Web TWAIN. It’s a background system service that handles the communication between connected physical devices and the browser, as well as image processing, encoding, decoding, etc.

Dynamsoft Service sets up a local HTTP service that accepts requests from JavaScript code running in the browser and performs operations accordingly. The following are a few examples.

NOTE

These requests are handled by the JavaScript client of the library. Please do not try to make similar requests in your own code without consulting Dynamsoft Support.
