PowerPoint文檔（幻燈片）是一種常見的演示文檔，在演講，教學，產品演示等方面得到廣泛的應用。本文將介紹如何通過編程的方式創建PowerPoint文檔。

創建簡單的PowerPoint文檔

//新建一個PowerPoint文檔（默認包含一頁空白幻燈片）
Presentation ppt = new Presentation();

//設置幻燈片大小和方向
ppt.SlideSize.Type = SlideSizeType.Screen16x9;
ppt.SlideSize.Orientation = SlideOrienation.Landscape;

//為幻燈片設置背景圖片
string ImageFile = "background.jpg";
RectangleF rect = new RectangleF(0, 0, ppt.SlideSize.Size.Width, ppt.SlideSize.Size.Height);
ppt.Slides[0].SlideBackground.Fill.FillType = FillFormatType.Picture;
IEmbedImage image = ppt.Slides[0].Shapes.AppendEmbedImage(ShapeType.Rectangle, ImageFile, rect);
ppt.Slides[0].SlideBackground.Fill.PictureFill.Picture.EmbedImage = image as IImageData;

//添加一個圖形（shape)到第一張幻燈片
IAutoShape textboxShape = ppt.Slides[0].Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 70, 600, 100));
textboxShape.ShapeStyle.LineColor.Color = Color.Transparent;
textboxShape.Fill.FillType = Spire.Presentation.Drawing.FillFormatType.None;

//清除圖形上的段落（默認有一個空白段落）
textboxShape.TextFrame.Paragraphs.Clear();

//在圖形上添加段落及內容
textboxShape.TextFrame.Paragraphs.Append(new TextParagraph());        
textboxShape.TextFrame.Paragraphs[0].TextRanges.Append(new TextRange("Spire.Presentation for .NET"));
textboxShape.TextFrame.Paragraphs[0].SpaceAfter = 50f;

//添加第二段及內容
textboxShape.TextFrame.Paragraphs.Append(new TextParagraph());
string text = "一款專業的 PowerPoint 組件，使用該組件，開發者可以在 .NET 平臺上對 PowerPoint 文檔進行生成、讀取、寫入、修改、"
             + "轉換和打印等操作。 作為一個獨立的控件，Spire.Presentation for .NET 的運行無需要安裝 Microsoft PowerPoint。";
textboxShape.TextFrame.Paragraphs[1].TextRanges.Append(new TextRange(text));

//設置段落中文字的字體、大小、顏色及段落的對齊方式、段首縮進距離
foreach (TextParagraph para in textboxShape.TextFrame.Paragraphs)
{
    para.TextRanges[0].LatinFont = new TextFont("Arial Rounded MT Bold");
    para.TextRanges[0].FontHeight = 13f;
    para.TextRanges[0].Fill.FillType = FillFormatType.Solid;
    para.TextRanges[0].Fill.SolidColor.Color = Color.Black;
    para.Alignment = TextAlignmentType.Left;
    para.Indent = 35;
}

//保存文檔
ppt.SaveToFile("創建PowerPoint.pptx", FileFormat.Pptx2013)

設置文檔屬性

//新建一個文檔
Presentation ppt= new Presentation();

//通過DocumentProperty設置文檔屬性
ppt.DocumentProperty.Application = "Spire.Presentation";
ppt.DocumentProperty.Author = "//www.e-iceblue.com/";
ppt.DocumentProperty.Company = "冰藍科技有限公司";
ppt.DocumentProperty.Keywords = "C#,PowerPoint文檔屬性";
ppt.DocumentProperty.Comments = "無";
ppt.DocumentProperty.Category = "PowerPoint教程";
ppt.DocumentProperty.Title = "如何為PowerPoint文檔添加屬性";
ppt.DocumentProperty.Subject = "Add document properties in C#";
ppt.DocumentProperty.Manager = "Gary";

//保存文檔
ppt.SaveToFile("設置文檔屬性.pptx", FileFormat.Pptx2013);
