Animation

What this page is about

Explore Aspose.Slides for Python via Java animation examples: add, access, remove, and sequence effects in PPT, PPTX, and ODP presentations.

This article demonstrates how to create simple animations and manage their sequence using Aspose.Slides for Python via Java.

Install the package as described in Installation. Each example imports asposeslides before starting the JVM, then imports the API after the JVM is running.

Add an Animation

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

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import EffectSubtype, EffectTriggerType, EffectType, Presentation, ShapeType

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 100, 100)

    # Apply a fade effect.
    slide.getTimeline().getMainSequence().addEffect(shape, EffectType.Fade, EffectSubtype.None_, EffectTriggerType.OnClick)
finally:
    presentation.dispose()

Access an Animation

Retrieve the first animation effect from the slide timeline.

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import EffectSubtype, EffectTriggerType, EffectType, Presentation, ShapeType

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 100, 100)
    slide.getTimeline().getMainSequence().addEffect(shape, EffectType.Fade, EffectSubtype.None_, EffectTriggerType.OnClick)

    # Access the first animation effect.
    effect = slide.getTimeline().getMainSequence().get_Item(0)
    print("Effect type:", effect.getType())
finally:
    presentation.dispose()

Remove an Animation

Remove an animation effect from the sequence.

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import EffectSubtype, EffectTriggerType, EffectType, Presentation, ShapeType

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 100, 100)
    effect = slide.getTimeline().getMainSequence().addEffect(shape, EffectType.Fade, EffectSubtype.None_, EffectTriggerType.OnClick)

    # Remove the effect.
    slide.getTimeline().getMainSequence().remove(effect)
finally:
    presentation.dispose()

Sequence Animations

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

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import EffectSubtype, EffectTriggerType, EffectType, Presentation, ShapeType

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    shape1 = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 100, 100)
    shape2 = slide.getShapes().addAutoShape(ShapeType.Ellipse, 200, 50, 100, 100)

    sequence = slide.getTimeline().getMainSequence()
    sequence.addEffect(shape1, EffectType.Fly, EffectSubtype.Bottom, EffectTriggerType.OnClick)
    sequence.addEffect(shape2, EffectType.Fly, EffectSubtype.Bottom, EffectTriggerType.OnClick)
finally:
    presentation.dispose()
