Thanks for contacting support.
You may use Aspose.Pdf libraries in C++ via COM Interop. However in order to register Aspose.Pdf for .NET with COM Interop you may follow the guidelines specified over “Aspose.Pdf for .NET via COM Interop” in our API documentation and to use the libraries in C++ please check “C++ via COM Interop” section in the documentation.
do you have the documentation that shows the c/c++ syntax
I am afraid that we have examples written only in C# and you may use any C# to C++ converter to get the syntax of C++. In case of any further assistance please feel free to contact us.
