Licensing Leave feedback

Sometimes, to study the system better, you want to dive into the code as fast as possible. To make this easier, GroupDocs.Watermark provides different purchase plans or offers a Free Trial and a 30-day Temporary License for evaluation.

Note

Note that there are several general policies and practices that guide you on how to evaluate, properly license, and purchase our products. You can find them in the “Purchase Policies and FAQ” section.

You can try GroupDocs.Watermark without buying a license.

The evaluation version is the same as the purchased one – the evaluation version simply becomes licensed when you set the license. You can set the license in several ways that are described in the next sections of this article.

The evaluation version comes with the following limitations:

• Only the first 2 pages can be processed.
• Trial badges are placed in the document on the top of each page.

If you wish to test GroupDocs.Watermark without the limitations of the trial version, you can also request a 30-day Temporary License. For details, see the “Get a Temporary License” page.

Note

You can find the pricing information on the “Pricing Information” page.

After getting the license, you need to set it. This section describes different ways to set the license.

The license should be set:

• Only once per application domain.
• Before using any other GroupDocs.Watermark classes.

Note

The license can be set multiple times per application domain, but we recommend doing it once since all the subsequent calls to the setLicense method except for the first one will just waste processor time.

The following code snippet shows how to set a license from a file:

const licensePath = "path to the .lic file";
const license = new groupdocs.watermark.License()
await license.setLicense(licensePath); 

The following code snippet shows how to set a license from a stream:

const java = require('java');
let InputStream = java.import('java.io.FileInputStream');

const licensePath = "path to the .lic file"
try {
  const stream = new InputStream(licensePath)

  const license = new groupdocs.watermark.License()
  await license.setLicense(stream);
  console.log('License set successfully.');
} catch {
  console.log("\nWe do not ship any license with this example. " +
