這篇文章主要介紹了C#/VB.NET 自定義PPT動畫路徑的步驟，幫助大家更好的理解和學習使用c#，感興趣的朋友可以了解下

程序運行環(huán)境如下：

.Net Framework 4.8
Visual Studio
Spire.Presentation.dll 6.4.5

所需引用的必要程序集文件如下圖：

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)
        {
            //創(chuàng)建一個幻燈片文檔(新建的文檔已默認包含一頁幻燈片）
            Presentation ppt = new Presentation();
            ISlide slide = ppt.Slides[0];//獲取第一頁空白幻燈片

            //添加形狀（指定形狀坐標、大小及相關格式設置）
            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;

            //給形狀設置動畫效果
            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;

            //保存文檔
            ppt.SaveToFile("CustomAnimation.pptx", FileFormat.Pptx2013);
            System.Diagnostics.Process.Start("CustomAnimation.pptx");
        }
    }
}
