Slide

This article provides a series of examples that demonstrate how to work with slides using Aspose.Slides for Python via .NET. You’ll learn how to add, access, clone, reorder, and remove slides using the Presentation class.

Each example below includes a brief explanation followed by a code snippet in Python.

Add a Slide

To add a new slide, you must first select a layout. In this example, we use the Blank layout and add an empty slide to the presentation.

def add_slide():
    with slides.Presentation() as presentation:
        # Each slide is based on a layout, which itself is based on a master slide.
        # Use the Blank layout to create a new slide.
        blank_layout = presentation.layout_slides.get_by_type(slides.SlideLayoutType.BLANK)

        # Add a new empty slide using the selected layout.
        presentation.slides.add_empty_slide(blank_layout)

        presentation.save("slide.pptx", slides.export.SaveFormat.PPTX)

💡 Tip: Each slide layout is derived from a master slide, which defines the overall design and placeholder structure. The image below illustrates how master slides and their associated layouts are organized in PowerPoint.

Access Slides by Index

You can access slides using their index. This is useful for iterating through or modifying specific slides.

def access_slide():
    with slides.Presentation("slide.pptx") as presentation:
        # Access a slide by index.
        first_slide = presentation.slides[0]

Clone a Slide

This example demonstrates how to clone an existing slide. The cloned slide is automatically added to the end of the slide collection.

def clone_slide():
    with slides.Presentation("slide.pptx") as presentation:
        slide = presentation.slides[0]

        # Clone the slide; it will be added at the end of the presentation.
        cloned_slide = presentation.slides.add_clone(slide)

        presentation.save("slide_cloned.pptx", slides.export.SaveFormat.PPTX)

Reorder Slides

You can change the order of slides by moving one to a new index. In this case, we move a slide to the first position.

def reorder_slide():
    with slides.Presentation("slide.pptx") as presentation:
        slide = presentation.slides[1]

        # Move the slide to the first position (others shift down).
        presentation.slides.reorder(0, slide)

        presentation.save("slide_reordered.pptx", slides.export.SaveFormat.PPTX)

Remove a Slide

To remove a slide, simply reference it and call remove. This example removes the first slide.

def remove_slide():
    with slides.Presentation("slide.pptx") as presentation:
        slide = presentation.slides[0]

        # Remove the slide.
        presentation.slides.remove(slide)

        presentation.save("slide_removed.pptx", slides.export.SaveFormat.PPTX)
