PPT中的动画效果可分为已有内置动画以及自定义动画。设置内置动画，只需直接指定动画效果类型即可。本文主要介绍如何实现自定义动画，即自定义形状动作线性路径。附C#及VB.NET代码供参考。
程序运行环境如下：
所需引用的必要程序集文件如下图：
C#
using Spire.Presentation;using Spire.Presentation.Collections;using Spire.Presentation.Drawing.Animation;using System.Drawing;namespace CustomAnimation{ class Program { static void Main(string[] args) { //创建一个幻灯片文档(新建的文档已默认包含一页幻灯片） Presentation ppt = new Presentation(); ISlide slide = ppt.Slides[0];//获取第一页空白幻灯片 //添加形状（指定形状坐标、大小及相关格式设置） IAutoShape shape = slide.Shapes.AppendShape(ShapeType.FivePointedStar, new RectangleF(100, 50, 180, 180)); shape.Fill.FillType = Spire.Presentation.Drawing.FillFormatType.Gradient; shape.Fill.Gradient.GradientStops.Append(0, KnownColors.SkyBlue); shape.Fill.Gradient.GradientStops.Append(1, KnownColors.Pink); shape.ShapeStyle.LineColor.Color = Color.White; //给形状设置动画效果 AnimationEffect effect = ppt.Slides[0].Timeline.MainSequence.AddEffect(shape, AnimationEffectType.PathUser); CommonBehaviorCollection common = effect.CommonBehaviorCollection; AnimationMotion motion = (AnimationMotion)common[0]; motion.Origin = AnimationMotionOrigin.Layout; motion.PathEditMode = AnimationMotionPathEditMode.Relative; MotionPath moinPath = new MotionPath(); moinPath.Add(MotionCommandPathType.MoveTo, new PointF[] { new PointF(0, 0) }, MotionPathPointsType.CurveAuto, true); moinPath.Add(MotionCommandPathType.LineTo, new PointF[] { new PointF(0.18f, 0.18f) }, MotionPathPointsType.CurveAuto, true); moinPath.Add(MotionCommandPathType.LineTo, new PointF[] { new PointF(-0.1f, 0.2f) }, MotionPathPointsType.CurveAuto, true); moinPath.Add(MotionCommandPathType.LineTo, new PointF[] { new PointF(0.25f, 0.2f) }, MotionPathPointsType.CurveAuto, true); moinPath.Add(MotionCommandPathType.End, new PointF[] { }, MotionPathPointsType.CurveStraight, true); motion.Path = moinPath; //保存文档 ppt.SaveToFile("CustomAnimation.pptx", FileFormat.Pptx2013); System.Diagnostics.Process.Start("CustomAnimation.pptx"); } }}
