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:

// Instantiates a Presentation object that represents a presentation file
using (Presentation pres = new Presentation("RemoveSlideUsingReference.pptx"))
{

    // Accesses a slide through its index in the slides collection
    ISlide slide = pres.Slides[0];

    // Removes a slide through its reference
    pres.Slides.Remove(slide);

    // Saves the modified presentation
    pres.Save("modified_out.pptx", 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:

// Instantiates a Presentation object that represents a presentation file
using (Presentation pres = new Presentation("RemoveSlideUsingIndex.pptx"))
{

    // Removes a slide through its slide index
    pres.Slides.RemoveAt(0);

    // Saves the modified presentation
    pres.Save("modified_out.pptx", 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:

using (Presentation pres = new Presentation("pres.pptx"))
{
    Aspose.Slides.LowCode.Compress.RemoveUnusedLayoutSlides(pres);
    
    pres.Save("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:

using (Presentation pres = new Presentation("pres.pptx"))
{
    Aspose.Slides.LowCode.Compress.RemoveUnusedMasterSlides(pres);
    
    pres.Save("pres-out.pptx", SaveFormat.Pptx);
}
