The following example shows how to generate thumbnails from PowerPoint Presentation.

auto pres = System::MakeObject<Presentation>(u"ThumbnailFromSlide.pptx");

// Access the first slide
auto slide = pres->get_Slides()->idx_get(0);
// Create a full scale image
System::SharedPtr<System::Drawing::Bitmap> bmp = slide->GetThumbnail(1.0f, 1.0f);
// Save the image to disk in JPEG format
bmp->Save(u"Thumbnail_out.jpg", System::Drawing::Imaging::ImageFormat::get_Jpeg());

The following example shows how to converting slides to bitmap and saving the images in PNG.

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

// Converts the first slide in the presentation to a Bitmap object
System::SharedPtr<System::Drawing::Bitmap> bmp = pres->get_Slides()->idx_get(0)->GetThumbnail();

// Saves the image in the PNG format
bmp->Save(u"Slide_0.png", System::Drawing::Imaging::ImageFormat::get_Png());

The following example shows how to convert PowerPoint PPT/PPTX to JPG.

auto pres = System::MakeObject<Presentation>(u"PowerPoint-Presentation.ppt");

for (auto&& slide : pres->get_Slides())
{
    // Create a full scale image
    System::SharedPtr<System::Drawing::Bitmap> bmp = slide->GetThumbnail(1.0f, 1.0f);
    // Save the image to disk in JPEG format
    bmp->Save(System::String::Format(u"Slide_{0}.jpg", slide->get_SlideNumber()),
              System::Drawing::Imaging::ImageFormat::get_Jpeg());
}

The following example shows how to convert PowerPoint PPT/PPTX to JPG with customized dimensions.

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

// Define dimensions
int32_t desiredX = 1200;
int32_t desiredY = 800;
// Get scaled values of X and Y
auto size = pres->get_SlideSize()->get_Size();
float scaleX = (float)(1.0 / size.get_Width()) * desiredX;
float scaleY = (float)(1.0 / size.get_Height()) * desiredY;
for (auto&& slide : System::IterateOver(pres->get_Slides()))
{
    // Create a full scale image
    System::SharedPtr<System::Drawing::Bitmap> bmp = slide->GetThumbnail(scaleX, scaleY);
    // Save the image to disk in JPEG format
    bmp->Save(System::String::Format(u"Slide_{0}.jpg", slide->get_SlideNumber()),
              System::Drawing::Imaging::ImageFormat::get_Jpeg());
}
