Animation

Shows how to create simple animations and manage their sequence using Aspose.Slides for Python via .NET.

Add an Animation

Create a rectangle shape and apply a fade effect triggered on click.

def add_animation():
    with slides.Presentation() as presentation:
        slide = presentation.slides[0]
        shape = slide.shapes.add_auto_shape(slides.ShapeType.RECTANGLE, 50, 50, 100, 100)

        # Add a fade in effect.
        slide.timeline.main_sequence.add_effect(
            shape,
            slides.animation.EffectType.FADE,
            slides.animation.EffectSubtype.NONE,
            slides.animation.EffectTriggerType.ON_CLICK)

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

Access an Animation

Retrieve the first animation effect from the slide timeline.

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

        # Access the first animation effect.
        effect = slide.timeline.main_sequence[0]

Remove an Animation

Remove an animation effect from the sequence.

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

        # Assuming the main sequence contains at least one effect.
        effect = slide.timeline.main_sequence[0]

        # Remove the effect.
        slide.timeline.main_sequence.remove(effect)

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

Sequence Animations

Add multiple effects and demonstrate the order in which animations occur.

def sequence_animations():
    with slides.Presentation() as presentation:
        slide = presentation.slides[0]
        shape1 = slide.shapes.add_auto_shape(slides.ShapeType.RECTANGLE, 50, 50, 100, 100)
        shape2 = slide.shapes.add_auto_shape(slides.ShapeType.ELLIPSE, 200, 50, 100, 100)

        sequence = slide.timeline.main_sequence
        sequence.add_effect(
            shape1,
            slides.animation.EffectType.FLY,
            slides.animation.EffectSubtype.BOTTOM,
            slides.animation.EffectTriggerType.ON_CLICK)
        sequence.add_effect(
            shape2,
            slides.animation.EffectType.FLY,
            slides.animation.EffectSubtype.BOTTOM,
            slides.animation.EffectTriggerType.ON_CLICK)

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