these are bitmaps not text. in addition to ocr, pdfs can also be generated directly from text.

However, when I open it in Preview, all VO announces are blank pages. I do have enough vision to see that there is text and diagrams presented on the screen. Could it be that OCR wasn't used to initially scan the document? Other Manufacturers Manuals present no problem what so ever. TNX all: Michael P S I could attach a copy if anyone has access to a scanner to re_produce the manual for reading. This manual is vary important to me.
