推荐答案

LaTeX 没有到 PDF 的一对一转换.关于您的第一个问题，我相信这种转换在技术上是可行的，但我不相信这样做的应用程序存在.类似于汇编程序可以反编译回高级语言的方式，可能有一种方法可以做到这一点.然而——一个pdf允许包含所有类型的数据——AutoCAD绘图、JPEG图形、字体文件、表格、数字签名等.LaTeX不知道这些东西是什么.所以第二个问题的答案是否定的——没有办法从任何 PDF 文档中提取等效的 LaTeX.

LaTeX does not have a one-to-one conversion to PDF. With regards to your first question, I believe such a conversion may be technically possible, but I do not believe an application to do so yet exists. Similar to the way assembler can be decompiled back into high level language, there is probably a way to do it. However -- a pdf is allowed to contain all matter of kinds of data -- AutoCAD drawings, JPEG graphics, font files, forms, digital signatures, etc. LaTeX has no idea what these things are. So in answer to the second question is no -- there's not a way to extract equivalent LaTeX from any PDF document.
