Slide Transition

What this page is about

Apply and remove slide transitions and set automatic slide advance timings with Aspose.Slides for Python via Java code examples for PPT, PPTX, and ODP presentations.

This article demonstrates applying slide transition effects and timings with 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 a Slide Transition

Apply a fade transition effect to the first slide.

import jpype
import asposeslides

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

from asposeslides.api import Presentation, TransitionType

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

    # Apply a fade transition.
    slide.getSlideShowTransition().setType(TransitionType.Fade)
finally:
    presentation.dispose()

Access a Slide Transition

Read the transition type currently assigned to a slide.

import jpype
import asposeslides

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

from asposeslides.api import Presentation, TransitionType

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

    slide.getSlideShowTransition().setType(TransitionType.Push)

    # Access the transition type.
    transition_type = slide.getSlideShowTransition().getType()
finally:
    presentation.dispose()

Remove a Slide Transition

Clear any transition effect. JPype exposes the Java constant named None as None_ because None is a reserved word in Python.

import jpype
import asposeslides

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

from asposeslides.api import Presentation, TransitionType

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

    slide.getSlideShowTransition().setType(TransitionType.Fade)

    # Remove the transition effect.
    slide.getSlideShowTransition().setType(TransitionType.None_)
finally:
    presentation.dispose()

Set Transition Duration

Specify how long the slide is displayed before advancing automatically. This example advances after two seconds and also allows advancing with a mouse click. This timing controls slide advance, not the speed of the transition effect.

import jpype
import asposeslides

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

from asposeslides.api import Presentation

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

    slide.getSlideShowTransition().setAdvanceOnClick(True)
    slide.getSlideShowTransition().setAdvanceAfter(True)
    slide.getSlideShowTransition().setAdvanceAfterTime(2000)  # In milliseconds.
finally:
    presentation.dispose()
