You can easily download GroupDocs.Annotation for evaluation. The evaluation download is the same as the purchased download. The evaluation version simply becomes licensed when you add a few lines of code to apply the license. You will face following limitations while using the API without the license:
- Only first 2 pages are processed.
- Trial badges are placed in the document on the top of each page.
The license file contains details such as the product name, number of developers it is licensed to, subscription expiry date and so on. It contains the digital signature, so don’t modify the file. Even inadvertent addition of an extra line break into the file will invalidate it. You need to set a license before utilizing GroupDocs.Annotation API if you want to avoid its evaluation limitations.
The license can be loaded from a file or stream object.
The code below will explain how to set product license.
The following example shows how to load a license from a stream.
