How is the upload done?

Dynamic Web TWAIN does the uploading in a few steps

  1. Grab the image(s) specified by indices ;
    • Encode the image(s) in the specified type which results in a binary file;
    • [Optional] Convert the file into a base64 string;
    • Create an HTTP Form and perform an asynchronous HTTP (Ajax) request to send the form to the specified url ;
    • Wait for the confirmation from the server.

The server-side script specified by url is very important, check out Server-side Scripting for more information.
