I want to get animation timeline effect property value as shown in the figure below:
Effect.jpg (407.8 KB)
How can I get “Zoom out to the center of the screen” or “outward”？
I guess I should use subType, right?

But the value seems wrong. Could you tell me how to solve it?

@oscarstar,
Unfortunately, I could not find such settings in PowerPoint. Could you please explain in more detail what it is or show me how to find it step by step?

I recorded how to set it. Please check the following screenshot.

@oscarstar,
Thank you for the video. I need some time, I will reply to you as soon as possible.

@oscarstar,
It looks like you should use the IEffect.getSubtype method, but it does not return the expected values for the Zoom effect. I’ve added a ticket with ID SLIDESJAVA-38992 to our issue-tracking system. Our development team will investigate the case. We will inform you of any progress.

Any update on this? I am also looking for a solution to find the effect property value. GetSubtype does not return correct value for some effects like Float, ascend

@pankajku,
Unfortunately, the issue is still open. I have informed our developers that you also need this functionality.

@oscarstar, @pankajku,
New members (SlideCenter and ObjectCenter) will be added for the EffectSubtype enum in Aspose.Slides for Java 24.10. These effect subtypes are used with the FadedZoom effect type.

Presentation pres = new Presentation("Reading.pptx");
ISequence mainSequence = pres.getSlides().get_Item(0).getTimeline().getMainSequence();

for (IEffect effect : mainSequence) {
    System.out.println(EffectType.getName(EffectType.class, effect.getType()) + ", " 
            + EffectSubtype.getName(EffectSubtype.class, effect.getSubtype()));
}

@oscarstar,
From the presentation file you provided, the code example above will print the following:

GrowAndTurn, None
