We have an AIM based document management system using Dynamic Web Twain
We use a custom built plug-in and it works flawlessly.
Instead of scanning and uploading from the file system using the AIM file upload process , the user scans directly onto the form. We place a scan button on the form, when the user clicks the button it initiates the scan process resulting in a pop up dialogue with the scanner. The user can manipulate the scanned documents in the dialogue box and then press submit for the upload to the AIM server and attachment to the Document object .
Scanning directly onto the form simplifies the process of scanning images to the server. It also ensures the correct image is uploaded, sometimes when using the file upload method its possible that the user uploads the incorrect file.
However , the current plug-in is outdated and needs to be upgraded to the new Dyn Web Twain version, so if you are keen to chip in for the plug-in upgrade let me know.
