使用Java或.NET库从ColdFusion对PDF执行光学字符识别？ [英] Performing Optical Character Recognition on PDF's from ColdFusion using a Java or .NET Library?

问题描述

我想要一个PDF并从中提取任何文本。然后我想使用ColdFusion的可用的Verity搜索来搜索内容。

I am looking to take a PDF and extract any text from it. I then want to make it available using ColdFusion's available Verity search to search the contents.

有没有任何库已经做得很好？我包括Java或.NET（Java优先）库，因为他们可以从CF调用。

Are there any libraries out there that do this quite well already? I am including Java or .NET (Java prefered) libraries in the scope since they can be called from CF.

任何见解或经验将非常感谢...感谢！

Any insights or experiences would be greatly appreciated... thanks!

编辑：索引PDF文件的工作原理是文本嵌入PDF，就我所知的CF。我必须处理的PDF文本扫描为图像。

Indexing PDF files works when the text is embedded in the PDF as far as I know with CF. The PDFs I'm having to deal with have the text scanned as an image.

推荐答案

如果您有能力运行自己的软件（即专用/ VPS），那么您可以使用 Tesseract OCR 与 cfexecute 以转换PDF到文本？

If you have the ability to run your own software (i.e. Dedicated/VPS) then you could investigate using Tesseract OCR with cfexecute to convert the PDFs to text?
