During Scanning Operation:

    1. Open dynamsoft.webtwain.install.js file
    2. Comment out the following code and add your own customized code
function OnWebTwainPreExecuteCallback(){ 
// Dynamsoft.WebTwainEnv.OnWebTwainPreExecute();

Set the property IfShowProgressBar to false. Please call the Load/Download methods synchronously, because the progress bar will still appear if you are calling them asynchronously.
