推荐答案

我自己能做的唯一方法是使用Adobe Acrobat本身，但不幸的是它不是免费的.

我找不到执行此操作的免费方法.

The only way I could do this myself was to use Adobe Acrobat itself, but unfortunatly it''s not free.

I couldn''t find a free way of doing this.

我不确定是否有任何免费方法可以执行此操作.我们使用名为Leadtools的第三方工具包，在对PDF文档进行OCR时会给我们带来很好的效果.我知道他们有一个在线演示，您可以尝试一下.这是演示的链接:

I''m not sure if there is any free way to do that. We use a third-party toolkit named leadtools that gives us very good results when OCRing PDF documents. I know that they have an online demo, you can try it. Here is the link for the demo:
