Anonimooltre 2 anni fa I am a long time user of LEADTOOLS SDK’s. We use some of their document features (scanning, cleanup, OCR) in our application and have never had any issues. We stay on their maintenance program because their OCR seems to get better with each version and this has helped us sell upgrades for our application! Our latest upgrade proved to be the best yet in terms of accuracy and performance.
I have always been impressed with the amount of sample code, demos, and thorough documentation. I rarely needed support but when I did, they were always quick to respond.
