Is there a C++ library to extract text from a PDF file like PDFBox for Java?
提问by Adam Smith
Last year, I made an application in Java using PDFBox to get the raw text in some PDF files and I need to port that application to C++ now.
去年，我使用 PDFBox 在 Java 中创建了一个应用程序来获取一些 PDF 文件中的原始文本，现在我需要将该应用程序移植到 C++。
I wanted to know what was the best C++ alternative to accomplish what I need.
我想知道什么是完成我需要的最佳 C++ 替代方案。
I'll give an example in case it helps:
如果有帮助，我将举一个例子：
Most files will look like this: http://www.jumbala.net/backup/league.pdf
大多数文件看起来像这样：http: //www.jumbala.net/backup/league.pdf
With PDFBox, using that file, each line read on page 2 and most of page 3 would output all the data of a line, separated by a space instead of keeping it in a grid like it is now.
使用 PDFBox，使用该文件，在第 2 页和第 3 页的大部分读取的每一行将输出一行的所有数据，用空格分隔，而不是像现在一样将其保留在网格中。
So the first relevant line in page 2 would look like this:
因此，第 2 页中的第一行将如下所示：
FB 847 - Tremblay, Gérard 179,63 56 16167 90 268 s27 p3 669 s14 199 223 193 615
or something like that since there are minor changes in the order they appear, but I don't care about that as long as similar lines output the same since I just parse them and put the values I need in different variables.
或者类似的东西，因为它们出现的顺序有细微的变化，但我不在乎，只要类似的行输出相同，因为我只是解析它们并将我需要的值放在不同的变量中。
So, knowing all of that, is there a library that I can use in a C++ program to get similar results?
那么，知道所有这些，是否有一个库可以在 C++ 程序中使用以获得类似的结果？
Edit:After looking at sacredFaith's link at http://www.codeproject.com/Articles/7056/Code-to-extract-plain-text-from-a-PDF-fileand trying it, I'm getting a weird output like such for the example file I mentioned earlier:
编辑：在http://www.codeproject.com/Articles/7056/Code-to-extract-plain-text-from-a-PDF-file查看了神圣信仰的链接并尝试之后，我得到了一个奇怪的输出就像我之前提到的示例文件：
http://www.jumbala.net/backup/league.pdf.txt
http://www.jumbala.net/backup/league.pdf.txt
The parts I actually need are in the weird characters at the beginning. Using Adobe Acrobat Reader X and using Save As... Text (accessible), I get the following result:
我真正需要的部分在开头的奇怪字符中。使用 Adobe Acrobat Reader X 并使用另存为...文本（可访问），我得到以下结果：
http://www.jumbala.net/backup/league_good.pdf.txt
http://www.jumbala.net/backup/league_good.pdf.txt
Which is approximately what I get in Java using PDFBox and what I want to get as output in C++.
这大约是我使用 PDFBox 在 Java 中获得的内容以及我想在 C++ 中作为输出获得的内容。
