c – 帮助以编程方式将文本添加到现有PDF

我需要编写一个显示第三方提供的PDF的程序.我需要在将文本数据显示给用户之前将其插入到表单中.我可以选择将PDF转换为另一种格式,但它必须与原始PDF完全相同. C是首选语言,但可以调查其他语言(例如C#).它需要在 Windows桌面计算机上运行.

您建议调查哪些库,工具,策略或其他编程语言来完成此任务？是否有任何在线示例可以指导我.

先感谢您.

PoDoFo怎么样：

The PoDoFo library is a free, portable C++ library which includes classes to parse PDF files and modify their contents into memory. The changes can be written back to disk easily. The parser can also be used to extract information from a PDF file (for example the parser could be used in a PDF viewer). Besides parsing PoDoFo includes also very simple classes to create your own PDF files. All classes are documented so it is easy to start writing your own application using PoDoFo.
