As an AutoIt user I would say AutoIt.
Copying text out of PDFs is not quite as simple as you might imagine. Mileage will vary on how the PDF was created, and there are several methods you can use:
- Most PDFs will have most of the text in the file itself, allowing you to get the text using a simple method like this
- This method uses zlib to do something to the pdf. Not sure what as I've never tried it.
- There are a variety of examples of using third party programs to do this, which may be better. There is one using Debenu and another using XPDF
- Automating other programs such as acrobat should be possible, in acrobats case they have an api that can be used, though I'm not aware of this already being wrapped in AutoIt.
As to the rest of the requirements, there is a UDF to translate with google translate here, and the word UDF is a standard one that comes with the AutoIt installation.
