The following example shows how to convert the first slide to the framed image with the RenderToGraphics method.

auto pres = System::MakeObject<Presentation>(u"Presentation.pptx");
auto slide = pres->get_Slide(0);

System::Drawing::Size slideSize(1820, 1040);
// Creates a Bitmap with the specified size (slide size + fields)
auto slideImage = System::MakeObject<System::Drawing::Bitmap>(slideSize.get_Width() + 50, slideSize.get_Height() + 50);

System::SharedPtr<System::Drawing::Graphics> graphics = System::Drawing::Graphics::FromImage(slideImage);

// Fills and translates Graphics to create a frame around the slide
graphics->Clear(System::Drawing::Color::get_Red());
graphics->TranslateTransform(25.0f, 25.0f);
// Renders the first slide to Graphics
slide->RenderToGraphics(System::MakeObject<RenderingOptions>(), graphics, slideSize);

// Saves the image in the JPEG format
slideImage->Save(u"FramedSlide_0.jpg", System::Drawing::Imaging::ImageFormat::get_Jpeg());

The following example shows how to conversion process for a slide with notes using the RenderToGraphics.

auto pres = System::MakeObject<Presentation>(u"PresentationNotes.pptx");
auto slide = pres->get_Slides()->idx_get(0);

// Gets the presentation notes size
System::Drawing::Size notesSize = pres->get_NotesSize()->get_Size().ToSize();
// Creates the rendering options
System::SharedPtr<IRenderingOptions> options = System::MakeObject<RenderingOptions>();
// Sets the position of the notes
System::SharedPtr<NotesCommentsLayoutingOptions> notesCommentsLayouting = System::MakeObject<NotesCommentsLayoutingOptions>();
notesCommentsLayouting->set_NotesPosition(NotesPositions::BottomTruncated);
options->set_SlidesLayoutOptions(notesCommentsLayouting);
// Creates a Bitmap with the notes' size
System::SharedPtr<System::Drawing::Bitmap> slideImage = System::MakeObject<System::Drawing::Bitmap>(notesSize.get_Width(), notesSize.get_Height());

// Renders the first slide to Graphics
System::SharedPtr<System::Drawing::Graphics> graphics = System::Drawing::Graphics::FromImage(slideImage);

slide->RenderToGraphics(options, graphics, notesSize);

// Saves the image in PNG format
slideImage->Save(u"Slide_Notes_0.png", System::Drawing::Imaging::ImageFormat::get_Png());
