    // This sample demonstrates all editing features of GcPdfViewer with support API
    // provided by the server running GcPdf. Note that unlike the viewer in most other
    // samples, in this sample the File Open button is available so you can load any PDF
    // into the viewer and see what its editing features can do with it.

    // This and other samples in this section demonstrate the features of GcPdfViewer
    // (a JavaScript PDF viewer control included with GcPdf), mainly the ability
    // to change PDF files (add or edit annotations and AcroForm fields, rotate pages etc.)
    // when the JS viewer on the client is supported by GcPdf running on the server.
    //
    // To enable the editing features of the viewer, its supportApi property must be set
    // to a URL on the server that implements all or some of the edit supporting APIs
    // that are known to/expected by the viewer. This GcPdf demo site provides those APIs,
    // which makes it possible to demonstrate the editing when you open the PDF viewer
    // in this sample. When you download this sample, in addition to the .NET Core
    // console app project that generates the sample PDF, an ASP.NET Core project is
    // also included in the download zip (located in the GcPdfViewerWeb sub-folder of the
    // downloaded zip), which also provides the necessary APIs. In particular, it includes
    // a project that implements the APIs and provides them via a special controller.
    // It is actually the same controller that is used by this GcPdf demo site, and which
    // can be used in any ASP.NET Core site to enable the viewer editing features.
    //
    // Look at the following files in the sample download zip for more info:
    // - GcPdfViewerWeb\SupportApiDemo: the sample ASP.NET Core web site.
    // - GcPdfViewerWeb\SupportApiDemo.sln: solution to build/run the sample web site.
    // - GcPdfViewerWeb\SupportApi: support API implementation (can be used in any site).
    // - GcPdfViewerWeb\SupportApi\Controllers\GcPdfViewerController.cs: support API controller.
    //
    // Please note that this and other samples in this section are only available in C# at this time.
