Java custom PPT animation motion path

Animation effects can be set for shapes in PPT slides. Common animation effects are built-in fixed types, that is, animation effects and paths are preset fixed templates, but when designing animation effects, users can also customize them according to their own preferences. Define the animation motion path. Below, the Java back-end program code is used to show how to implement a custom action path.

The test environment includes:

• Target test document: Power Point 2013

• Compilation environment: IntelliJ IDEA 2018

• JDK version: 1.8.0

• PPT library: spire.presentation.jar 4.3.2

Note: When adding animation type (AnimationEffectType) through this PPT library, about 150 different types can be added. This article takes the custom type setting animation path as an example to introduce.
