New Features and Enhancements

Other Improvements and Changes

Public API Changes

New methods ILoadOptions::get_DeleteEmbeddedBinaryObjects() and ILoadOptions::set_DeleteEmbeddedBinaryObjects() have been added

The property allows you to remove embedded binary data from a presentation file while loading.

The possible binary data in the presentation:

• VBA Project
• OLE Object embedded data
• ActiveX Control binary data

This property can be useful for removing malicious binary content. The following code sample shows how to load the presentation and save it without malware content:

System::SharedPtr<LoadOptions> loadOptions = System::MakeObject<LoadOptions>();
loadOptions->set_DeleteEmbeddedBinaryObjects(true);

System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>(u"malware.ppt", loadOptions);
pres->Save(u"clean.ppt", Aspose::Slides::Export::SaveFormat::Ppt);

New methods IPdfOptions::get_IncludeOleData() and IPdfOptions::set_IncludeOleData() methods have been added

The property allows you to export files embedded in the presentation to PDF format.

The following example shows how to export a presentation to PDF, including embedded files:

System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>(u"pres.pptx");
System::SharedPtr<PdfOptions> options = System::MakeObject<PdfOptions>();
options->set_IncludeOleData(true);
pres->Save(u"pres.pdf", Aspose::Slides::Export::SaveFormat::Pdf, options);

ILayoutPlaceholderManager interface and LayoutPlaceholderManager class have been added

The new interface ILayoutPlaceholderManager represents methods that can be used to add a new placeholder to the Layout slide.

The following types of placeholders can be added:

• Content
• Vertical Content
• Text
• Vertical Text
• Picture
• Chart
• Table
• SmartArt
• Media
• Online Image

New method ILayoutSlide::get_PlaceholderManager() has been added

The property allows access to a placeholder manager of the Layout slide.

The following code sample shows how to add new placeholder shapes to the Layout slide:

System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>();

// Getting the Blank layout slide
System::SharedPtr<ILayoutSlide> layout = pres->get_LayoutSlides()->GetByType(Aspose::Slides::SlideLayoutType::Blank);

// Getting the placeholder manager of the layout slide
System::SharedPtr<ILayoutPlaceholderManager> placeholderManager = layout->get_PlaceholderManager();

// Adding different placeholders to the Blank layout slide
placeholderManager->AddContentPlaceholder(10.0f, 10.0f, 300.0f, 200.0f);
placeholderManager->AddVerticalTextPlaceholder(350.0f, 10.0f, 200.0f, 300.0f);
placeholderManager->AddChartPlaceholder(10.0f, 350.0f, 300.0f, 300.0f);
placeholderManager->AddTablePlaceholder(350.0f, 350.0f, 300.0f, 200.0f);

// Adding the new slide with Blank layout
System::SharedPtr<ISlide> newSlide = pres->get_Slides()->AddEmptySlide(layout);

pres->Save(u"placeholders.pptx", Aspose::Slides::Export::SaveFormat::Pptx);
