Depends on what actually _is_ in the PDF file. If every page is
represented as a picture, 650 pictures will be created. If it
contains text _and_ images, the images will be output, if will
_only_ output the images, with no real realtion to where they
have been placed in the text. As suggested by the name "pdfimages"
it takes the images from the PDF file. :-)

The easiest way to check for possible text is to install xpdf
which brings the binary "pdftotext" (if I remember correctly that
this tool is in _that_ package). You can then use it like this:

	% pdftotext source.pdf

It will create "source.txt" with all actual text (but of course
without _any_ formatting except line breaks and ^L page breaks),
including page numbers. But hey, it's pure ASCII text suitable
for further processing. :-)

Run "pdftotext" without parameters for a short summary of its
parameters; "man pdftotext" is also provided.
