Can web spiders read and harvest e-mail addresses from a pdf file ?

Many users and folks like QRZ.com are using jpegs not ascii for listing
e-mails -- this seems to work.

So for pdf files without going to a jpeg --- are ascii text addresses
harvestable ?

Yes, in the sense that Optical Character Recognition (OCR) programs _can_
read text out of an image. In practice, it's not worth the spammers' or
web spider operators' trouble -- or that's been my experience, anyway.

YMMV.
