通过提供文件名创建演示文档
本主题演示如何使用 Open XML SDK 中的类以编程方式创建演示文稿文档。
创建演示文稿
和 Open XML 标准定义的所有文件一样,演示文稿文件由包文件容器组成。 用户在其文件资源管理器中可看到该文件;该文件的扩展名通常为 .pptx。 包文件在 Open XML SDK 中由 PresentationDocument 类表示。 演示文稿文档包含演示文稿部件和其他部件。
在 Open XML SDK 中由 PresentationPart 类表示的演示文稿部件包含幻灯片演示文稿的基本 PresentationML 定义。 PresentationML 是用于创建演示文稿的标记语言。 每个包只能包含一个演示文稿部件,并且其根元素必须为 <presentation/>
。
用于创建新演示文稿文档包的 API 调用相对简单。 第一步是调用 类的PresentationDocument静态Create方法,如 此处所示CreatePresentation
,此过程是本文后面介绍的完整代码示例的第一部分。 代码 CreatePresentation
调用 方法的替代, Create
该方法将新文档的路径和要创建的演示文稿文档的类型作为参数。
该参数中可用的演示文稿文档的类型由 PresentationDocumentType 枚举值定义。
接下来,代码调用 AddPresentationPart,这将创建并返回 PresentationPart
。
PresentationPart
创建类实例后,通过将 属性设置为Presentation从调用类构造函数返回的 类实例Presentation,为演示文稿添加新的Presentation
根元素。
为创建完整、可用和有效的演示文稿,代码还必须向演示文稿包添加许多其他部分。 在示例代码中,通过调用名为 CreatePresentationsParts
的实用工具函数来解决此问题。 然后该函数调用许多其他实用工具函数,这些函数一起创建基本演示文稿所需的所有演示文稿部分,包括幻灯片、幻灯片版式、幻灯片母版和主题部分。
static void CreatePresentation(string filepath)
{
// Create a presentation at a specified file path. The presentation document type is pptx, by default.
using (PresentationDocument presentationDoc = PresentationDocument.Create(filepath, PresentationDocumentType.Presentation))
{
PresentationPart presentationPart = presentationDoc.AddPresentationPart();
presentationPart.Presentation = new Presentation();
CreatePresentationParts(presentationPart);
}
}
使用 Open XML SDK,可以使用对应于 PresentationML 元素的强类型类来创建演示文稿结构和内容。 可以在 命名空间中找到 DocumentFormat.OpenXml.Presentation 这些类。 下表列出了与演示文稿、幻灯片、幻灯片母版、幻灯片版式和主题元素相对应的类的名称。 与主题元素对应的类实际上是 命名空间的一 DocumentFormat.OpenXml.Drawing 部分。 主题是所有 Open XML 标记语言共用的。
PresentationML 元素 | Open XML SDK 类 |
---|---|
<presentation/> |
Presentation |
<sld/> |
Slide |
<sldMaster/> |
SlideMaster |
<sldLayout/> |
SlideLayout |
<theme/> |
Theme |
接下来的 PresentationML 代码是包含两张幻灯片的简单演示文稿的演示文稿部分(在文件 presentation.xml 中)中的 XML。
<p:presentation xmlns:p="…" … >
<p:sldMasterIdLst>
<p:sldMasterId xmlns:rel="https://…/relationships" rel:id="rId1"/>
</p:sldMasterIdLst>
<p:notesMasterIdLst>
<p:notesMasterId xmlns:rel="https://…/relationships" rel:id="rId4"/>
</p:notesMasterIdLst>
<p:handoutMasterIdLst>
<p:handoutMasterId xmlns:rel="https://…/relationships" rel:id="rId5"/>
</p:handoutMasterIdLst>
<p:sldIdLst>
<p:sldId id="267" xmlns:rel="https://…/relationships" rel:id="rId2"/>
<p:sldId id="256" xmlns:rel="https://…/relationships" rel:id="rId3"/>
</p:sldIdLst>
<p:sldSz cx="9144000" cy="6858000"/>
<p:notesSz cx="6858000" cy="9144000"/>
</p:presentation>
