创建幻灯片

本页介绍了如何向现有 Google 幻灯片演示文稿添加幻灯片。

幻灯片

Google 幻灯片演示文稿的每个单独页面都是一个幻灯片

如需向演示文稿中添加幻灯片,您需要提供演示文稿 ID。您可以通过在 Google 幻灯片中打开演示文稿并查看其网址来找到演示文稿的 ID:

https://docs.google.com/presentation/d/presentationID/edit

如需添加幻灯片,请将 batchUpdate() 方法与演示文稿 ID 搭配使用,并在请求正文中添加 CreateSlideRequest。响应正文中会返回新幻灯片的 ID。

示例

以下示例展示了如何向演示文稿添加幻灯片。CreateSlideRequest 的所有字段均为选填字段。此示例将幻灯片创建为第二个幻灯片,并采用 TITLE_AND_TWO_COLUMNS 布局和显式对象 ID。

创建幻灯片后,您可以向其中添加文字和形状。

填充占位符

布局通常包含占位符形状,这些形状会在创建幻灯片时复制到幻灯片中。借助 CreateSlideRequest,您可以通过 placeholderIdMappings 字段指定用于这些复制占位符的对象 ID。这样,您就可以在同一 batchUpdate 请求中修改复制的占位符,从而提高性能并节省配额。如需了解详情,请参阅 CreateSlideRequest 示例
