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. PDF files contain the underlying text strings and search engines index them without OCR'ing. Whether spammers bother, I don't know. Hi, Paul. Long time no see. Depends on whether they're text-based PDF or image-based PDF. If I scan a page into a JPEG or TIFF and then convert that to PDF, it may not have any of the text as text, and I think it's improbable that it will. -- Mike Andrews, W5EGO Tired old sysadmin |
