Document Scanning from ASP.net Web Application

Question

I have a ASP.Net C# 4.0 Web Application

I need to Add a scanning feature for my users. This is what I want to achieve On my web application

1. user clicks on a button
2. opens a window with preview of document in Scanning device attached to the client system
3. User confirms the Scan
4. this will save the Scanned document in jpg/pdf format on the server
5. then do the OCR on document

Can any one suggest a way to achieve this.

I read about this https://www.leadtools.com/sdk/engine/imaging not sure how much this can work. Can any one suggest a best way to get this done.

Thanks

update

tried leadtools from https://www.leadtools.com/support/forum/posts/m28036-Re--Scan-and-Upload-v16--NET-with-Caspol-exe-deployment as LEAD Support suggested but it is missing references not sure where and how to get those references

Answer 1

HaBo, This is LEAD support. Since you mentioned our LEADTOOLS toolkit, the answer to your question is yes. Our toolkit can be used to implement either of the 2 approaches mentioned by tgolisch.

For the click-once approach, you simply use our Windows Forms controls that contain Twain support and package your application for ClickOnce deployment. This is done, for example, in this demo project: LEADTOOLS ClickOnce Demos

For the custom control approach, see the example code projects on our forums that perform Scan and Upload
