我需要编写一个程序，用于显示第三方提供的PDF文件。程序需在将文本数据展示给用户之前，将其插入到表格中。我可以选择将PDF转换为其他格式，但转换后的内容必须与原始PDF完全一致。首选语言是C，但可以使用其他语言。
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.
