按照本文操作，使用 Java REST API 向 PowerPoint 添加评论。您将学习如何使用基于 Java 的 Cloud SDK 自动添加使用 Java Low Code API 的 PowerPoint 评论。它将分享在将评论添加到幻灯片之前设置评论的各种参数的详细信息。
先决条件
下载 Aspose.Slides Cloud SDK for Java for inserting comments in the slides
使用上述 SDK 设置 Java 项目以向幻灯片添加评论
使用基于 Java 的 API 对 PowerPoint 演示文稿进行评论的步骤
- 通过设置添加评论的客户端 ID 和密钥来创建 SlidesApi 对象
- 设置输入演示文稿文件名和目标幻灯片索引
- 定义幻灯片评论和相关子评论集合
- 使用 CreateComment 方法向幻灯片添加评论
- 获取评论数以确认添加评论
- 下载包含新评论的更新后的演示文稿文件
这些步骤描述了如何使用 Java RESTful 服务在 PowerPoint 中添加注释。设置输入演示文稿文件名和幻灯片索引，创建幻灯片注释和子注释，然后通过设置输入文件名、目标索引和注释来调用 CreateComment() 方法插入注释。此调用上传演示文稿，在云中对其进行修改，并返回注释集合。

此代码演示了如何使用 Java RESTful 服务向 PowerPoint 演示文稿添加注释。您可以通过添加注释列表并将其设置为属性 ChildComments，在主注释下添加多个子注释。您可以通过使用 SlideComment 方法设置其他公开的属性来自定义注释。
本文教我们如何在幻灯片中添加注释。您可以按照文章 使用 Java REST API 在 PowerPoint 中使用图片作为背景 为演示文稿插入图像背景。
