问题
I'm looking for a free way to create a large batch of tif files (10-20k) into PDF files, ideally with OCR too.
It needs to be callable from the command line in windows.
回答1:
You can use the XnView application. It's got command line too.
Another alternative might be IrfanView.
回答2:
You can try LibTiff.Net library for this. It comes with tiff2pdf utility that can be used to create PDF from TIFF files. Unfortunately, there is no support for OCR.
Disclaimer: I am one of the maintainers of the library.

You could possibly use GhostScript to create a PDF from a Tiff via commandline. Or build your own commandline app using iTextSharp to create PDF files.
Not sure about OCRing tho...
