Question

我有一个任务，我必须通过每张幻灯片并将其输入到docx文件，我的条件是我不会使用interop或我可以使用openXML。

目前我正在尝试拍摄每张幻灯片的图像并将这些图像插入到文档中。我从here获得了sampleCode（在spire dll的帮助下），它产生了每张幻灯片的图像。但问题是，在创建图像时，DLL会在图像的顶部放置一个水印（水印文本：评估警告：文档......）是否有任何其他选项来获取幻灯片的图像或直接将幻灯片输入到doc文件。还有一件事我无法购买其他许可证

Answer 1

首先：只需支付许可证费用。水印是有原因的。

要回答您的问题，Open XML文档实际上是一个ZIP文件，因此从那里提取嵌入文件非常容易，甚至可以编辑它们。您只需将文件解压缩为ZIP，对其执行任务，然后再将其压缩。

您不需要额外的库来执行此操作，但有些库可能会使zip处理更容易一些。如果您不想使用外部库，则需要使用System.IO.Compression下提供的类。

您可以使用OpenXML在文档中添加图像，首先需要将幻灯片转换为单个图像然后逐个放置在搜索之后，我得到以下代码片段以在word文档中插入图像

using DocumentFormat.OpenXml.Wordprocessing;
using DocumentFormat.OpenXml;
using Wp = DocumentFormat.OpenXml.Drawing.Wordprocessing;
using A = DocumentFormat.OpenXml.Drawing;
using Pic = DocumentFormat.OpenXml.Drawing.Pictures;

namespace GeneratedCode
{
    public class GeneratedClass
    {
        // Creates an Body instance and adds its children.
        public Body GenerateBody()
        {
            Body body1 = new Body();

        presetGeometry1.Append(adjustValueList1);

        shapeProperties1.Append(transform2D1);
