C＃PDFSharp：如何从PDF文本剥离的例子？ [英] C# PDFSharp: Examples of how to strip text from PDF?

问题描述

我有一个相当简单的任务：我需要阅读PDF文件，并写出它的图像内容而忽视了其文本内容。所以基本上我需要做的另存为文本的补充。

I have a fairly simple task: I need to read a PDF file and write out its image contents while ignoring its text contents. So essentially I need to do the complement of "save as text".

在理想情况下，我宁愿避免任何形式的图像内容重新压缩，但如果它的不可能的，这是确定了。

Ideally, I would prefer to avoid any sort of re-compression of the image contents but if it's not possible, it's ok too.

是如何做到这一点的例子吗？

Are the examples of how to do it?

谢谢！
