Example

The following example code shows the use of the Img method to send images to connected Windows SideShow-compatible devices. The example shows how to reference images that are located in the gadget's assembly, as well an external image stored in a local directory.

private static void SampleImg()
{
    // Set the gadget's GUID.
    Guid gadgetId = new Guid("{0530B726-F6D5-4a66-900E-3C7673316F3B}");

    // Add the gadget's registry subkey and values.
    GadgetRegistration.Register(
        false,                           // Register gadget for current user only
        gadgetId,                        // Guid for the registry subkey
        ScfSideShowGadget.ScfEndpointId, // Endpoints registry value
        "Example SideShow gadget",       // FriendlyName registry value
        null,                            // StartCommand registry value
        null,                            // Icon registry value, this gadget will use the generic gadget icon.
        false,                           // OnlineOnly registry value
        GadgetCachePolicies.KeepNewest,  // CachePolicy registry value
        null);

    // Construct a Simple Content Format SideShow gadget for the gadget's Guid.
    using (ScfSideShowGadget gadget = new ScfSideShowGadget(gadgetId))
    {
        // Add Glance content showing date/time of last update
        gadget.AddGlanceContent(
           String.Format("Content updated on {0}{1:D}.", Environment.NewLine, DateTime.Now));

        // Set ids.
        int mainMenuId = ScfSideShowGadget.HomePageContentId;
        int textPageId = 4;
        int imagePageId = 5;
        int imageId = 7;

        // Create the main menu page.
        string content = Scf.Body(
            Scf.Menu(mainMenuId, "Simple Gadget Menu", ScfSelectAction.Target,
                Scf.Item(textPageId, "See the text page"),
                Scf.Item(imagePageId, "See the image Page")));
        // Send the menu page to connected SideShow devices.
        gadget.AddContent(content);

        // Create the text page.
        content = Scf.Body(
            Scf.Content(textPageId, "This is the Text Page",
                Scf.Txt(ScfAlign.Left, true, Color.Green, "This is some Green text")));
        // Send the text page to connected SideShow devices.
        gadget.AddContent(content);

        // Create the image page using the Img method.
        content = Scf.Body(
            Scf.Content(imagePageId, "This is the image page.",
                Scf.Img(imageId, ScfAlign.Center, ScfImageFit.Auto, "Alt image text."),
                Scf.Txt(ScfAlign.Center, true, Color.Black, "Image caption.")));
        // Send the image page to connected SideShow devices.
        gadget.AddContent(content);

        // Send an image from a local directory to connnected SideShow devices.
        string imageLocation = @"C:\Users\Public\SideShowGadget\HungerForce.jpg";
        gadget.AddContent(imageId, ImageContentTransforms.KeepAspectRatio, new Bitmap(imageLocation));

        // Send an image from the this gadget's assembly to connnected SideShow devices.
        Stream imageStream = Assembly.GetEntryAssembly().GetManifestResourceStream("CodeSampleSideShow.ExcelSaga.jpg");
        gadget.AddContent(imageId, ImageContentTransforms.KeepAspectRatio,
           Image.FromStream(imageStream));
    }
}
