  • C#/VB.NET 向PowerPoint文档插入视频

    如今,Microsoft Office PowerPoint在我们日常生活中的应用已经很广泛了,利用Microsoft Office PowerPoint不仅可以创建演示文稿,还可以在互联网上召开面对面会议、远程会议或在网上给观众展示演示文稿等。那么,怎样做出有趣、生动、美观的PowerPoint文档呢?其中一个很好的选择就是向文档中插入视频。这样可以使读者更好地理解文档的内容,增加读者的兴趣。那么开发者如何通过编程的方式来实现这一功能呢?本文将给大家分享如何使用免费版PowerPoint组件—Spire.Presentation以C#/VB.NET编程的方式来向PPT文档插入视频。

    Spire.Presentation简介

    Spire.Presentation for .NET是一款专业的PowerPoint兼容组件,使开发人员能够在.NET平台(C#,VB.NET,ASP.NET)上创建,读,写,修改,转换和打印PowerPoint文档,并且不需要安装Microsoft PowerPoint软件。Spire.Presentation for .NET 支持的格式有PPT,PPS,PPTX及PPSX。它提供了很多实用的功能,如管理文本,图像,形状,表格,动画,音频和视频等。此外,它还支持将幻灯片导出为EMF,JPG,TIFF,PDF等格式。

    有需要的朋友可以从E-iceblue官网下载安装。

    下面是详细步骤:

    注意:在创建项目后,添加相关.dll文件作为项目引用。

    代码片段:

    步骤1:新建一个PPT文档。

    Presentation presentation = new Presentation();

    步骤2:使用presentation.Slides[0].Shapes.AppendVideoMedia()方法来插入视频。

    presentation.Slides[0].Shapes.AppendVideoMedia(@"小毛驴.mp4", new RectangleF(100, 100, 20, 20));  //用户可以根据自己的需要来设置参数的大小

    步骤3:添加形状来展示文本并保存PPT文档。

    IAutoShape shape = presentation.Slides[0].Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 150, 600, 250));  //用户可以根据自己的需要来设置参数的大小
    
    presentation.SaveToFile("video.pptx", FileFormat.Pptx2010);

    效果图:

                           

    全部代码:

    C#:

    using System.Drawing;
    
    using System.IO;
    
    using Spire.Presentation;
    
    using Spire.Presentation.Drawing;
    
    namespace InsertVideo
    
    {
    
        class Program
    
        {
    
            static void Main(string[] args)
    
            {
    
                Presentation presentation = new Presentation();
    
     
    
                //设置背景图片
    
                string ImageFile = @"花朵.jpg";
    
                RectangleF rect = new RectangleF(0, 0, presentation.SlideSize.Size.Width, presentation.SlideSize.Size.Height);
    
                presentation.Slides[0].Shapes.AppendEmbedImage(ShapeType.Rectangle, ImageFile, rect);
    
                presentation.Slides[0].Shapes[0].Line.FillFormat.SolidFillColor.Color = Color.FloralWhite;
    
     
    
                presentation.Slides[0].Shapes.AppendVideoMedia(@"小毛驴.mp4", new RectangleF(100, 100, 20, 20));
    
     
    
                IAutoShape shape = presentation.Slides[0].Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 150, 600, 250));
    
                shape.ShapeStyle.LineColor.Color = Color.White;
    
                shape.Fill.FillType = Spire.Presentation.Drawing.FillFormatType.None;
    
                shape.AppendTextFrame("我有一只小毛驴我从来也不骑,有一天我心血来潮骑着去赶集,");
    
     
    
                shape.TextFrame.Paragraphs.Append(new TextParagraph());
    
                shape.TextFrame.Paragraphs[1].TextRanges.Append(new TextRange("我手里拿着小皮鞭我心里正得意,不知怎么哗啦啦啦我摔了一身泥。"));
    
                foreach (TextParagraph para in shape.TextFrame.Paragraphs)
    
                {
    
                    para.TextRanges[0].LatinFont = new TextFont("Arial Rounded MT Bold");
    
                    para.TextRanges[0].Fill.FillType = FillFormatType.Solid;
    
                    para.TextRanges[0].Fill.SolidColor.Color = Color.Black;
    
                    para.Alignment = TextAlignmentType.Left;
    
                    para.Indent = 35;
    
                }
    
     
    
                presentation.SaveToFile("video.pptx", FileFormat.Pptx2010);
    
                System.Diagnostics.Process.Start("video.pptx");
    
            }
    
        }
    
    }

    Imports System.Drawing
    Imports System.IO
    Imports Spire.Presentation
    Imports Spire.Presentation.Drawing
    Module Module1
     
        Sub Main()

            '设置背景图片
            Dim ImageFile As String = "花朵.jpg"
            Dim rect As New RectangleF(0, 0, presentation.SlideSize.Size.Width, presentation.SlideSize.Size.Height)
            presentation.Slides(0).Shapes.AppendEmbedImage(ShapeType.Rectangle, ImageFile, rect)
            presentation.Slides(0).Shapes(0).Line.FillFormat.SolidFillColor.Color = Color.FloralWhite
     
            presentation.Slides(0).Shapes.AppendVideoMedia("小毛驴.mp4", New RectangleF(100, 100, 20, 20))
     
            Dim shape As IAutoShape = presentation.Slides(0).Shapes.AppendShape(ShapeType.Rectangle, New RectangleF(50, 150, 600, 250))
            shape.ShapeStyle.LineColor.Color = Color.White
            shape.Fill.FillType = Spire.Presentation.Drawing.FillFormatType.None
            shape.AppendTextFrame("我有一只小毛驴我从来也不骑,有一天我心血来潮骑着去赶集,")
     
            shape.TextFrame.Paragraphs.Append(New TextParagraph())
            shape.TextFrame.Paragraphs(1).TextRanges.Append(New TextRange("我手里拿着小皮鞭我心里正得意,不知怎么哗啦啦啦我摔了一身泥。"))
            For Each para As TextParagraph In shape.TextFrame.Paragraphs
                para.TextRanges(0).LatinFont = New TextFont("Arial Rounded MT Bold")
                para.TextRanges(0).Fill.FillType = FillFormatType.Solid
                para.TextRanges(0).Fill.SolidColor.Color = Color.Black

            Next
     
            presentation.SaveToFile("video.pptx", FileFormat.Pptx2010)
            System.Diagnostics.Process.Start("video.pptx")
