Licensing

Aspose.OMR for C++ is a commercially licensed product that can be used in trial (evaluation) mode.

Free trial

You can start using Aspose.OMR for C++ right after the installation.

In trial mode (without providing a license) you can design, generate, and recognize OMR forms. However, the following restrictions apply:

A watermark is added to print forms generated by Aspose.OMR for C++.
Only the first 5 elements of the template source are rendered on print forms. The remaining elements are ignored.
Only the first 5 answers are recognized on the filled forms. The remaining answers are ignored.

Apply a license to remove the restrictions.

Getting a temporary license

A temporary license removes all limitations of the trial version for 30 days. Use it to start building a fully functional OMR application and make the final decision to purchase Aspose.OMR for C++ later.

To request a temporary license, visit “Get a Temporary License” page.

Purchasing a license

Aspose.OMR for C++ is licensed either by the number of developers and locations (sites) where the products will be used (Developer and Site licenses) or by pay-per-use (Metered licenses).

Read License Types for details and purchase a license that best suits your needs.

After downloading the license file, you can rename it and even change its extension.

Applying a license

After receiving a purchased or temporary license, load it in your application’s code. Insert the following code in your startup method before calling any other Aspose.OMR for C++ methods:

// Initialize the licensing object
auto license = System::MakeObject<License>();

// Load the license from file
license->SetLicense(u"Aspose_OMR_CPP_License_File.lic");

If no path is provided, SetLicense method will look for the license file in the folder that contains Aspose.OMR for C++ component and in the folder of the application. If you prefer to load the license from the explicit path, provide the full path in SetLicense method.

Licensing multiple Aspose products

Even if you have a single license file for all Aspose products (such as Aspose.Total), you still need to apply the license separately to each Aspose product you are using in your application.

Each Aspose product has a License class in its namespace. Use the fully qualified License class name when applying licenses to each product to avoid ambiguity; for example:

// Aspose.OMR
  auto omrLicense = System::MakeObject<License>();
  omrLicense->SetLicense(u"Aspose_OMR_CPP_License_File.lic");

// Aspose.BarCode
  auto barcodeLicense = System::MakeObject<License>();
  barcodeLicense->SetLicense(u"Aspose_Barcode_CPP_License_File.lic");
