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.

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");
