18.1 (01/12/2023)

Dynamic Web TWAIN v18.1 is restructured into two editions. While the standard Service Edition focuses on interactions with scanners, the Plus Edition offers support for mobile cameras as well. The goal is to make sure the Service Edition is small-sized, easy-to-use, and stable. The Plus Edition, on the other hand, is more comprehensive and offers flexibility in platforms and devices.

The following table gives a quick comparison between the two editions.

NOTE:

Plus Edition is a temporary edition as its enhanced features will be separated into another SDK product by the end of 2023. Due to the upcoming change, the Plus Edition is not available to download from the public website. If you want to access the Plus Edition now, please send a request to us.
