如何通过Cloud Python SDK从PDF中删除链接
要删除PDF中的链接,我们将使用 Aspose.PDF Cloud Python SDK. 此Cloud SDK协助Python程序员通过Aspose.PDF REST API使用Python编程语言开发基于云的PDF创建、批注、编辑和转换应用程序。只需在Aspose for Cloud创建一个账户并获取应用程序信息。一旦您获得应用程序SID和密钥,即可以使用Aspose.PDF Cloud Python SDK。如果Python包托管在Github上,可以直接从Github安装:
从Github安装
pip install git+https://github.com/aspose-pdf-cloud/aspose-pdf-cloud-python.git
包管理器控制台命令
pip install asposepdfcloud
通过Python SDK删除PDF中的链接的步骤
Aspose.PDF Cloud开发人员可以轻松加载并删除PDF中的链接。
- 安装Python SDK
- 将PDF文档上传到Aspose Cloud服务器
- 从Aspose Cloud服务器下载处理后的PDF文档
- 获取特定PDF文档的所有超链接注解
- 删除所有链接
