auto presentation = MakeObject<Presentation>(u"presentation.ppt");
presentation->Save(u"document.pdf", SaveFormat::Pdf);
presentation->Dispose();

Add Animation to Presentations

Adding animations to presentation elements can make slides more interactive and engaging.

auto presentation = MakeObject<Presentation>();
auto slide = presentation->get_Slides()->idx_get(0);

auto autoShape = slide->get_Shapes()->AddAutoShape(ShapeType::Rectangle, 20, 20, 150, 100);

auto textFrame = autoShape->get_TextFrame();
textFrame->set_Text(u"First paragraph \nSecond paragraph \n Third paragraph");

// Get the main animation sequence of the slide.
auto mainSequence = slide->get_Timeline()->get_MainSequence();

// Add the Fade animation effect to the shape.
auto effect = mainSequence->AddEffect(autoShape, EffectType::Fade, EffectSubtype::None, EffectTriggerType::OnClick);

// Animate the shape text by first-level paragraphs.
effect->get_TextAnimation()->set_BuildType(BuildType::ByLevelParagraphs1);

presentation->Save(u"animated_text.pptx", SaveFormat::Pptx);
presentation->Dispose();

Save PowerPoint Slides to Images

Aspose.Slides for C++ can render presentation slides as images. This is useful for previews, web pages, documents, and video workflows.

The C++ code demonstrates how to convert a presentation to JPG images.

auto presentation = MakeObject<Presentation>(u"presentation.pptx");

auto desiredSize = Size(1200, 800);

for (auto&& slide : presentation->get_Slides())
{
    // Generate an image of the slide with the specified dimensions.
    auto image = slide->GetImage(desiredSize);

    // Save the image to disk in JPEG format.
    auto fileName = String::Format(u"slide_{0}.jpg", slide->get_SlideNumber());
    image->Save(fileName, ImageFormat::Jpeg);
    image->Dispose();
}

presentation->Dispose();

Convert Presentations to Video

Aspose.Slides for C++ can generate presentation frames that can be assembled into video files with tools such as FFmpeg.

void OnFrameTick(SharedPtr<PresentationPlayer> sender, SharedPtr<FrameTickEventArgs> args)
{
    auto fileName = String::Format(u"frame_{0}.png", sender->get_FrameIndex());
    args->GetFrame()->Save(fileName);
}

void Run()
{
    auto presentation = MakeObject<Presentation>(u"Presentation.pptx");

    const int fps = 33;

    auto animationsGenerator = MakeObject<PresentationAnimationsGenerator>(presentation);

    auto player = MakeObject<PresentationPlayer>(animationsGenerator, fps);
    player->FrameTick += OnFrameTick;

    animationsGenerator->Run(presentation->get_Slides());

    const String ffmpegParameters = String::Format(
        u"-loglevel {0} -framerate {1} -i {2} -y -c:v {3} -pix_fmt {4} {5}",
        u"warning", fps, "frame_%d.png", u"libx264", u"yuv420p", "video.mp4");

    auto ffmpegProcess = Process::Start(u"ffmpeg", ffmpegParameters);
    ffmpegProcess->WaitForExit();

    presentation->Dispose();
