Examples Overview

1. Set License from File

Load and apply a license from a .lic file stored on disk. This is the most common way to license Aspose.TeX.

Use Case: Standard licensing for desktop applications or server deployments where the license file is stored locally.

2. Set License from Stream

Load and apply a license from a Stream object. Useful when the license file is embedded as a resource or retrieved from a database or cloud storage.

Use Case: Applications where the license is not stored as a physical file, such as embedded resources or cloud-based storage.

3. Set Metered License

Configure metered (pay-as-you-go) licensing by providing public and private keys. With metered licensing, you're charged based on actual API usage.

Key Features:

• Pay-per-Use: Only pay for what you actually process
• No Upfront Costs: No need to purchase a full license upfront
• Usage Tracking: Monitor your API consumption
• Flexible Scaling: Automatically scales with your needs

Use Case: Applications with variable or unpredictable usage patterns, SaaS platforms, or when you want to minimize upfront licensing costs.

How to Get Metered Keys:

1. Visit Aspose Purchase
2. Select the "Metered License" option
3. Obtain your public and private keys
4. Use Metered.SetMeteredKey() to activate

4. Clear License

Remove a previously installed license to return to evaluation mode. Useful for testing or when switching between different licenses.

Use Case: Development/testing scenarios where you need to verify evaluation mode behavior, or when temporarily disabling licensing.
