Evaluation Version Limitations
Customers can test the API thoroughly before making a final decision to buy it. However, the API has certain evaluation limitations if you will use it without a license. These limitations include:
- The number of drawing operations is limited to 100 and an exception will be thrown after that
- A watermark is embedded in output image when user saves the image
Apply License using File or Stream Object
The license can be loaded from a file or stream object. The easiest way to set a license is to put the license file in the same folder as the Aspose.Drawing.dll/Aspose.Drawing.Common.dll file and specify the file name, without a path, as shown in the example below.

Aspose.Drawing allows developers to apply metered key. It is a new licensing mechanism. The new licensing mechanism will be used along with existing licensing method. Those customers who want to be billed based on the usage of the API features can use the metered licensing. For more details, please refer to Metered Licensing FAQ section.
A new class Metered has been introduced to apply metered key. Following is the sample code demonstrating how to set metered public and private keys.
