Remove Slide from Presentation

Sometimes, developers may need to remove a slide from the presentation due to any reason. Aspose.Slides for C++ offers few methods to do so. In this topic, we will explore these methods to accomplish this task. We know that Presentation class in Aspose.Slides for C++ represents a presentation file. Presentation class encapsulates a ISlideCollection that acts as a repository of all slides that are the part of the presentation. Developers can remove a slide from this Slides collection in two ways:

1. Using Slide Reference
2. Using Slide Index

Remove Slide by Reference

To remove a slide using its reference, please follow the steps below:

1. Create an instance of Presentation class.
2. Obtain the reference of a slide by using its Id or Index.
3. Remove the referenced slide from the presentation.
4. Write the modified presentation file.

For complete examples and data files, please go to https://github.com/aspose-slides/Aspose.Slides-for-C

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

	// Instantiate Presentation class
	SharedPtr<Presentation> pres = MakeObject<Presentation>(templatePath);

	// Accessing Slide by ID from collection
	SharedPtr<ISlide> slide = pres->get_Slides()->idx_get(0);

	// Removing a slide using its reference
	pres->get_Slides()->Remove(slide);

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

Remove Slide by Index

To remove a slide using its index position in the slides collection of the presentation, please follow the steps below:

1. Create an instance of Presentation class.
2. Remove the slide from the presentation by using its index position.
3. Write the modified presentation file.

For complete examples and data files, please go to https://github.com/aspose-slides/Aspose.Slides-for-C

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

	// Instantiate Presentation class
	SharedPtr<Presentation> pres = MakeObject<Presentation>(templatePath);

	// Removing a slide using its slide index
	pres->get_Slides()->RemoveAt(0);

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