Hi Will,
Hi;
Yes, Open Book and Kurzweil do allow you to print to a virtual printer
driver so that you may perform OCR on PDF documents. However, the problem
with this approach in terms of the PDF digital rights management system, is
that a publisher can disable printing of that PDF document, rendering
conventional OCR useless. I can think of a way to perform OCR, but it would
be restricted to the currently visible portion of the Window, and would be
CPU intensive, as it would work based on the GDI GetPixel() function.
So, the only way to guarantee accessibility to PDF documents, in my opinion,
is for the ability to turn off content extraction by access technology to be
taken out of Adobe's DRM system. The other methods either have technical or
legal implications.
Will

Hi Kevin -- I have a question: Do the various book reading programs suchasOpenBook and K1000 do much the same thing as this program? I know theaccessbeprograms do much more than OCR in that they also speak and read DAISY and brf and who knows what else, but not having used any of them as yet, I'dinterested in knowing more about pdfmagic and what exactly it translatesthepdf document to.ones.
Also, there is a program called pdfconvert that I bought from scansoft.com
for $49 that translates pdf docs to Microsoft Word format with all forms,
images and layout preserved. Obviously this is useful for pdf access, but
what I'm wondering is how this would work with a pdf doc with the
accessibility options turned off. I have never tried it on such a file.
Also, jaws 6.0 and acrobat 7.0 are now working together better than ever
before to make pdf docs accessible, so could you please tell me more about
the access options that you say can be turned on or off by publishers? Is
this still a problem? or are all pdf docs now accessible?
Confused...
Thanks in advance.

also, there's a program called pdf magic you can buy it from www.readingmadeeasy.com along with other similar tools. this program performs ocr on pdf files thus extracting even the lockedhadit costs around $60 and I have found it very useful.

Hi;
I've just downloaded a few e-books from Amazon, and thought I would notify
you of the current state of affairs, as books are useful in a range of
situations.
Whilst Adobe still allow content publishers to disallow content extraction
by access technology, meaning screen readers won't be able to read books
that have had this option disallowed, more publishers are allowing it. I
downloaded about three books published by John Wiley and son. All thesecontent extraction by access technology allowed, which was something Wileycontent
turned off in their e-books only six or so months ago. So, it looks like
Wiley books are now accessible, as well as those from some smaller
publishers.
Whilst persuading publishers to allow access is a difficult task, and one Adobe should have taken the lead on by not allowing them to disableextraction by access technology, it does seem as some of the bigpublishershttp://www.freedomscientific.com/fs_support/documentation/JAWS_Scripting_Docare now gaining social consciences.
