PDF文件操作 [英] PDF document manipulation

问题描述

我有几个具有以下属性的PDF:

I have several PDFs with the following properties:

每个PDF都包含可变数量的文档"，它们具有不同的页数.

Each PDF contains a variable number of "documents" with differing number of pages.

文档"中的每个页面都有诸如"26页中的第3页"之类的文本.

Each page in a "document" has text such as "Page 3 of 26".

我希望能够自动识别PDF中每个文档"的首页和最后一页(注意:这与PDF的首页和最后一页不同，因为每个PDF可能包含多个文档" )，然后将其提取到新的PDF中，以供以后打印和存档.

I want to be able to automatically identify the first and last page of each "document" within a PDF (Note: this is not the same as the first and last page of a PDF as each PDF may contain several "documents") and extract these into a new PDF for later printing and archival.

我不确定我可以带些什么工具来解决这个问题，以及哪些库可以用来解决这个问题.

I'm not sure what tools I can bring to bear on this problem and what libraries are available to tackle this.

有什么建议吗?最好是免费的，可用于创建将在Windows上运行的工具.

Any recommendations? Preferably free and can be used to create a tool that will run on Windows.
