Is an OCR package available for Debian 4.0, in .deb form, that can read
from PDF files, to allow text to be extracted from PDF files?
In looking at what is available in Synaptic, I could not find such a
package.
Thank you in anticipation.

Yes ... From PDF? I do not know but implimenting it is simple with some
filtering.
Questio is more on quality or correctness of OCR result. So far, I have
mixed result of very bad and fairly usable. None was very good.
I think its database needs to be trained.

Use aptitude which has better searching capability. Here is my search
result of graphic tools including OCR.

Since sending the above message, due to something that happened, where I
had to cite material that was in a PDF document that was published on
the Internet, I clicked on the link for the PDF document, in Iceape
(which I use for accessing web pages when I want to write an email using
material in the web pages, as Iceape includes the email facility, like
the Netscape and Mozilla suites), and the document viewer (Adobe Reader
8.0) opened the document within the tab, and I was able to simply mark
and copy and paste the text, as if it was simply text in an HTML web
page, or in a word processor document.
So, Adobe Reader 8.0 provides the text extraction, or copying, that I
sought, so an OCR application that imports text from PDF files, is now
probably redundant (other than that it could function as a smaller,
standalone, application, but this seems to be adequate).
Now, if only I could print from Adobe Reader 8.0 (I can print PDF files
from Evince 0.4.0, but not from Adobe 8.0)...

Only for PDFs that have got text in them. Some PDFs have scanned
pages, which we can read, but there's no text to extract; It's a
graphic file when all's said and done. You'll need OCR for the images.

The OP can use "netpbm" to pipe the PDF through the module and then into
the ORC software...
Have a nice Day/Evening
