C# PPT 为形状设置三维效果

在PPT中，形状是非常重要的元素。3-D形状，立体多元，给人耳目一新的感觉。在幻灯片中添加3-D效果形状，必然会为PPT的整体效果增色不少。为形状设置三维格式时，可设置棱台，轮廓线，表面效果等。

本篇文章，旨在介绍在使用免费的Spire.Presentation，独立创建Powerpoint文档，添加形状，并设置三维效果。感兴趣的朋友，可以从E-iceblue官网下载免费的Spire.Presentation。下载完成后，请将bin文件夹的.dll添加作为引用。友情提示：使用Spire.Presentation可独立创建powerpoint文档。

需要添加的命名空间：

using Spire.Presentation;
using Spire.Presentation.Drawing;
using System.Drawing;

步骤详叙：

步骤一：创建PPT文档。

Presentation presentation = new Presentation();

步骤二：添加形状，设置其位置，大小并填充颜色。

IAutoShape shape1 = presentation.Slides[0].Shapes.AppendShape(ShapeType.RightArrow, new RectangleF(150, 150, 150, 150));
shape1.Fill.FillType = FillFormatType.Solid;
shape1.Fill.SolidColor.KnownColor = KnownColors.RoyalBlue;

步骤三：为该形状设置三维效果。

ShapeThreeD Demo1 = shape1.ThreeD.ShapeThreeD;
//设置表面效果
Demo1.PresetMaterial = PresetMaterialType.Matte;
//设置棱台类型，高度和宽度
Demo1.TopBevel.PresetType = BevelPresetType.ArtDeco;
Demo1.TopBevel.Height = 4;
Demo1.TopBevel.Width = 12;
//设置轮廓线类型，颜色，宽度
Demo1.BevelColorMode = BevelColorType.Contour;
Demo1.ContourColor.KnownColor = KnownColors.LightBlue;
Demo1.ContourWidth = 3.5;

步骤四：再添加一个形状作为对照。

IAutoShape shape2 = presentation.Slides[0].Shapes.AppendShape(ShapeType.Pentagon, new RectangleF(400, 150, 150, 150));
shape2.Fill.FillType = FillFormatType.Solid;
shape2.Fill.SolidColor.KnownColor = KnownColors.LawnGreen;
ShapeThreeD Demo2 = shape2.ThreeD.ShapeThreeD;
Demo2.PresetMaterial = PresetMaterialType.SoftEdge;
Demo2.TopBevel.PresetType = BevelPresetType.SoftRound;
Demo2.TopBevel.Height = 12;
Demo2.TopBevel.Width = 12;
Demo2.BevelColorMode = BevelColorType.Contour;
Demo2.ContourColor.KnownColor = KnownColors.LawnGreen;
Demo2.ContourWidth = 5;

步骤五：保存文档为.pptx，启动查看效果。

presentation.SaveToFile("result.pptx", FileFormat.Pptx2010);
System.Diagnostics.Process.Start("result.pptx");
