Dynamsoft TWAIN Products

We currently use a TWAIN web control in our in-house application in ASP. We are upgrading our app to ASP.NET, but the current vendor's control doesn't meet our needs. Here are a few of our wishes.

1. We need to be able to insert/delete a page out of a document that has already been scanned and saved to disk and save it back.

2. In the event of a paper jam in the feeder, we want to be able to resume scanning into the same image file once we fix the jam.

3. We need some type of resume feature...say you're scanning a 50 page document...scanning is finished and then I load another 50 pages...will it append those new scanned images to the current scan?

4. I was wondering about the capacity of the buffer. Our current control updates the .tif file as pages are scanned in. From what I see, Dynamic TWAIN holds the scans in some kind of memory until the user decides to save the file. How will the buffer handle large documents. 50-80+ pages?

You can use Dynamic Web TWAIN (DWT) to finish these issues. In DWT, the LoadImage method or the LoadImageEx method can be used to load saved images to Dynamic Web TWAIN. After loading the images, you can do the operations to these images, such as append, delete and re-save images. For more information of these, please refer to:

Also, in the new version of Dynamic Web TWAIN (DWT 5.1), some new features are added in the product. You can insert new images into any position of scanned images then.



New scanned images will automatically append to the images in buffer. Also, you can do as above using DWT. First save the images, then load the image file and do the scanning.



Yes. New scanned images will append to the images in buffer.



The maximum number of images you can scan is 1024.

Thanks.
