推荐答案

LaTeX没有对PDF的一对一转换.关于您的第一个问题，我认为从技术上讲这样的转换是可能的，但是我不认为存在这样的转换.类似于可以将汇编程序反编译为高级语言的方法，可能有一种方法可以实现.但是-允许pdf包含所有类型的数据-AutoCAD图形，JPEG图形，字体文件，表格，数字签名等.LaTeX不知道这些是什么.因此，对第二个问题的回答是否"-无法从任何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.
