Google 幻灯片 API 的一个实用应用是将来自一个或多个数据源的信息合并到一个模板化的幻灯片组。
本页概述了如何从外部来源获取数据，并将其插入现有模板演示文稿。此概念类似于使用文字处理程序和电子表格进行邮件合并的概念。
此方法实用的原因有：
设计人员可以使用 Google 幻灯片编辑器轻松微调演示文稿的设计。这比调整应用中的参数来设置渲染的幻灯片设计要简单得多。
将内容与演示文稿分离是一个众所周知的设计原则，它具有许多优势。
基本食谱
以下示例说明了如何使用幻灯片 API 将数据合并到演示文稿中：
您可以使用占位符内容创建您希望呈现的演示文稿，以帮助您设计。
对于您要插入的每个内容元素，请将占位符内容替换为标记。标记是具有唯一字符串的文本框或形状。请务必使用一般不会出现的字符串。例如，
{{account-holder-name}}可能就是一个不错的标记。在代码中，使用 Google Drive API 创建演示文稿的副本。
在您的代码中，通过幻灯片 API 的
batchUpdate方法和一组replaceAllText请求来执行整个演示文稿中的所有文本替换。使用replaceAllShapesWithImage请求可在整个展示过程中执行图片替换。
创建包含标记的演示文稿后，请务必创建副本，并使用幻灯片 API 处理副本。请勿使用幻灯片 API 处理您的主“模板”副本！
下面几部分提供的代码段展示了此过程中的部分内容。您还可以观看上面的视频，查看完整示例 (Python)，该示例组合了下面各个部分中的多个概念。
合并文本
您可以使用 replaceAllText 请求将演示文稿中给定文本字符串的所有实例替换为新文本。对于合并，这比逐一查找和替换文本的每个实例更简单。这种方法是最复杂的方法之一，因为页面元素 ID 难以预测，特别是在协作者优化和维护模板呈现时。
示例
此示例使用 Drive API 复制了模板演示文稿，并创建了演示文稿的新实例。然后使用 Google 表格 API 从表格电子表格读取数据，最后使用幻灯片 API 更新新演示文稿。
该示例从电子表格中某个命名范围中某一行的 3 个单元格中获取数据。然后，只要出现字符串 {{customer-name}}、{{case-description}} 或 {{total-portfolio}}，它就会用该数据替换呈现中的数据。

合并图片
您还可以使用 replaceAllShapesWithImage 请求将图片合并到演示文稿中。此请求会将包含提供的文本字符串的形状的所有实例替换为提供的图片。该请求会自动调整图片的位置和缩放比例，以适应标记形状的边界，同时保持图片的宽高比不变。
示例
此示例使用 Google Drive API 复制了模板演示文稿，并生成了演示文稿的新实例。然后，它使用 Slides API 查找包含文本 {{company-logo}} 的任何形状，并将其替换为公司徽标图片。该请求还会将任何形状替换为文本 {{customer-graphic}}，并替换为其他图片。

替换特定文本框或图片实例
replaceAllText 和 replaceAllShapesWithImage 请求对于替换整个演示文稿中的标记非常有用，但有时您只需根据其他条件（例如位于特定幻灯片中）替换元素。
在这些情况下，您必须检索要替换的标记形状的 ID。对于文本替换，请删除这些形状中的现有文本，然后插入新文本（请参阅在指定的形状中编辑文本示例）。
图像替换则较为复杂。如需在图片中进行合并，您需要执行以下操作：
- 获取标记形状的 ID。
- 从代码中复制尺寸和转换信息。
- 使用大小和变形信息将图片添加到页面。
- 删除标记形状。
在保持图片的宽高比的同时将图片缩放到所需大小时，您可能需要谨慎操作，如下一部分所述。另请参阅此示例：将形状标记替换为图片。
保持宽高比
使用幻灯片 API 创建图片时，宽高比仅取决于图片大小，而不是大小和转换数据。系统会将您在 createImage 请求中提供的尺寸数据视为图片所需的尺寸。该 API 会根据此所需大小调整图片的宽高比，然后应用提供的转换。
将标记替换为图片时，您可以通过按如下方式设置图片的大小和缩放比例来保持图片的宽高比：
- width：设为代码的
width和scaleX的乘积 - height：设置为代码的
height与scaleY的乘积 - scale_x：设置为
1 - scale_y：设为
1
这样一来，Slides API 就会根据标签的视觉大小（而非未缩放比例）调整图片的宽高比（请参阅将形状标记替换为图片）。
将缩放比例参数设置为 1 可防止图片被缩放两次。
这种安排可确保图片的宽高比保持不变，并防止图片超出标记形状的大小。图片的中心点与标记形状的中心点相同。
管理模板
对于应用定义并拥有的模板演示文稿，请使用代表应用的专用帐号创建模板。 服务帐号是一个不错的选择，可以避免限制共享的 Google Workspace 政策的复杂性。
通过模板创建演示文稿的实例时，请始终使用最终用户凭据。这可让用户完全控制生成的呈现方式，并可防止出现与 Google 云端硬盘中每位用户限制相关的扩缩问题。
如需使用服务帐号创建模板，请使用应用凭据执行以下步骤：
- 在幻灯片 API 中使用 presentations.create 创建演示文稿。
- 更新权限，允许演示文稿收件人使用 Drive API 中的 permissions.create 进行读取。
- 更新权限，允许模板作者使用 Drive API 中的 permissions.create 进行写入操作。
- 根据需要修改模板。
如需创建演示文稿的实例，请使用用户凭据执行以下步骤：
- 在 Drive API 中使用 files.copy 创建模板的副本。
- 在幻灯片 API 中使用 presentation.batchUpdate 替换值。
