Remove Slide from Presentation

If a slide (or its contents) becomes redundant, you can delete it. Aspose.Slides provides the Presentation class that encapsulates ISlideCollection, which is a repository for all slides in a presentation. Using pointers (reference or index) for a known ISlide object, you can specify the slide you want to remove.

Remove Slide by Reference

1. Create an instance of the Presentation class.
2. Get a reference of the slide you want to remove through its ID or Index.
3. Remove the referenced slide from the presentation.
4. Save the modified presentation.

This C++ code shows you how to remove a slide through its reference:

	// The path to the documents directory
	const String templatePath = L"../templates/AddSlides.pptx";
	const String outPath = L"../out/RemoveSlidesByReference.pptx";

	// Instantiates a Presentation object that represents a presentation file
	SharedPtr<Presentation> pres = MakeObject<Presentation>(templatePath);

	// Accesses a slide through its index in the slides collection
	SharedPtr<ISlide> slide = pres->get_Slides()->idx_get(0);

	// Removes a slide through its reference
	pres->get_Slides()->Remove(slide);

	// Saves the modified presentation
	pres->Save(outPath, Aspose::Slides::Export::SaveFormat::Pptx);

Remove Slide by Index

1. Create an instance of the Presentation class.
2. Remove the slide from the presentation through its index position.
3. Save the modified presentation.

This C++ code shows you how to remove a slide through its index:

	// The path to the documents directory
	const String templatePath = L"../templates/AddSlides.pptx";
	const String outPath = L"../out/RemoveSlidesByID.pptx";

	// Instantiates a Presentation object that represents a presentation file
	SharedPtr<Presentation> pres = MakeObject<Presentation>(templatePath);

	// Removes a slide through its slide index
	pres->get_Slides()->RemoveAt(0);

	// Saves the modified presentation
	pres->Save(outPath, Aspose::Slides::Export::SaveFormat::Pptx);

Remove Unused Layout Slide

Aspose.Slides provides the RemoveUnusedLayoutSlides() method (from the Compress class) to allow you to delete unwanted and unused layout slides. This C++ code shows you how to remove a layout slide from a PowerPoint presentation:

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

LowCode::Compress::RemoveUnusedLayoutSlides(pres);

pres->Save(u"pres-out.pptx", SaveFormat::Pptx);

Remove Unused Master Slide

Aspose.Slides provides the RemoveUnusedMasterSlides() method (from the Compress class) to allow you to delete unwanted and unused master slides. This C++ code shows you how to remove a master slide from a PowerPoint presentation:

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

LowCode::Compress::RemoveUnusedMasterSlides(pres);

pres->Save(u"pres-out.pptx", SaveFormat::Pptx);
