I don't know what version of pdftotext you are using, but the
latest versions include support for LZW by "piping" the compressed data out
to another process (behind your back). I was one of the people who
contributed that part of the code.

We've talked a similar approach in our SPDF library, due to
licensing problems with those "wonderful" folks at Unisys.

I don't believe that any of the PDF ActiveX/COM objects support
content extraction.
