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.Comparison 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.Comparison 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 a number of ways that described in the next sections of this article.

The evaluation version comes with the limitations:

• Only 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.Annotation 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 of GroupDocs.Annotation classes.

Note

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

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

License lic = new License();
lic.setLicense(licensePath);

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

License lic = new License();
lic.setLicense(licenseInputStream);

You can also set the Metered license as an alternative to license file. It is a new licensing mechanism that will be used along with existing licensing method. It is useful for the customers who want to be billed based on the usage of the API features. For details, please refer to the Metered Licensing FAQ section.

The following code snippet shows how to use Metered licensing:

String publicKey = ""; // Your public license key
String privateKey = ""; // Your private license key

Metered metered = new Metered();
metered.setMeteredKey(publicKey, privateKey);

// Get amount (MB) consumed
double amountConsumed = Metered.getConsumptionQuantity();
System.out.println("Amount (MB) consumed: " + amountConsumed);

// Get count of credits consumed
double creditsConsumed = Metered.getConsumptionCredit();
System.out.println("Credits consumed: " + creditsConsumed);
