Class ComHelper



  • public class ComHelper
    extends Object

    Provides methods for COM clients to load a document into Aspose.Pdf.


    Use the ComHelper class to load a document from a file or stream into a Document object in a COM application. The Document class provides a default constructor to create a new document and also provides overloaded constructors to load a document from a file or stream. If you are using Aspose.Words from a .NET application, you can use all of the Document constructors directly, but if you are using Aspose.Pdf from a COM application, only the default Document constructor is available.
