// Create an "ImageSaveOptions" object which we can pass to the document's "Save" method
// to modify the way in which that method renders the document into an image.
auto imgOptions = MakeObject<ImageSaveOptions>(SaveFormat::Png);
// Set the "PaperColor" property to a transparent color to apply a transparent
// background to the document while rendering it to an image.
imgOptions->set_PaperColor(System::Drawing::Color::get_Transparent());
doc->Save(ArtifactsDir + u"ImageSaveOptions.PaperColor.Transparent.png", imgOptions);
// Set the "PaperColor" property to an opaque color to apply that color
// as the background of the document as we render it to an image.
