C# 操作PPT图形

本文将介绍如何使用Spire.Presentation for .NET操作幻灯片里面的图形,比如旋转图形、重置图形的大小与位置、调整重叠图形的顺序等。
工具/原料
1

Spire.Presentation for .NET

2

Visual Studio

方法/步骤
1

下载并安装Spire.Presentation for .NET, 并将Spire.Presentation.dll文件引用到项目中。

2

将代码放入Visual Studio中:旋转图形【C#】using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using Spire.Presentation;namespace Rotate_Shapes{       class Program            {                       static void Main(string[] args)                        {                                //创建一个PowerPoint文档并加载示例文档                                 Presentation ppt = new Presentation();                                ppt.LoadFromFile('Sample.pptx');                               //获取第一个幻灯片里的第一个图形                               IShape shape = ppt.Slides[0].Shapes[0];                               //旋转180度                                shape.Rotation = 180;                               //保存文档                               ppt.SaveToFile('Rotate.pptx', FileFormat.Pptx2010);                        }             }}

重置图形的大小【C#】using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using Spire.Presentation;using System.Drawing;namespace Reset_Shape_Size{          class Program                {                         static void Main(string[] args)                           {                               //创建一个PowerPoint文档并加载示例文档                                Presentation ppt = new Presentation();                                ppt.LoadFromFile('Sample.pptx');                                //获取原始幻灯片高度和宽度                              float currentHeight = ppt.SlideSize.Size.Height;                               float currentWidth = ppt.SlideSize.Size.Width;                              //将幻灯片大小设置为A3.                               ppt.SlideSize.Type = SlideSizeType.A3;                              //获取新幻灯片的高度和宽度                               float newHeight = ppt.SlideSize.Size.Height;                               float newWidth = ppt.SlideSize.Size.Width;                              //指定高度和宽度的比例                               float ratioHeight = newHeight / currentHeight;                               float ratioWidth = newWidth / currentWidth;                  //重新设置图形大小和位置                 foreach (ISlide slide in ppt.Slides)                     {                            foreach (IShape shape in slide.Shapes)                               {                                        //重置图形大小                                       shape.Height = shape.Height * ratioHeight;                                      shape.Width = shape.Width * ratioWidth;                                       //重置图形位置                                      shape.Left = shape.Left * ratioHeight;                                       shape.Top = shape.Top * ratioWidth;                                   }                                    //保存文档                                ppt.SaveToFile('ResetSizePosition.pptx', FileFormat.Pptx2010);                           }                 }         }}

重新排列重叠图形的顺序【C#】using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using Spire.Presentation;namespace Reorder_Shapes      {                class Program                    {                           static void Main(string[] args)                               {                                       //创建一个PowerPoint文档并加载示例文档                                       Presentation ppt = new Presentation();                                       ppt.LoadFromFile('Sample.pptx');                                       //获取第二个幻灯片里的第一个图形                                       IShape shape = ppt.Slides[1].Shapes[0];                                       //重新设置图形的顺序.                                      ppt.Slides[1].Shapes.ZOrder(1, shape);                                      //保存文档                                        ppt.SaveToFile('Reorder.pptx', FileFormat.Pptx2010);                       }               }}
