An addendum to this thread: the company bought Acrobat 9 Standard, and to my dismay, it can't really edit PDFs as you'd expect a word processor to. This from its Help:
"It’s a fact that Adobe® PDF is unlike other document formats, in which you can freely copy, paste, and move text and images on a page. Instead, consider a PDF as a snapshot of your original file. Use Adobe® Acrobat® 9 Standard to touch up and enhance the file for readability and distribution, and reserve more substantial revisions for your source application."
The Advanced Editing TouchUp Text Tool is very hard to use. It deleted text I hadn't marked, and screwed up formatting when I tried to add anything or to close up gaps. Adobe 9 does not really convert into Word DOC format either. The DOC output is only RTF with the extension changed, and very minor internal changes from "official" RTF output. These RTFs do not always import properly into Word, which sometimes locks up with "This application is not responding" messages. Strangely, they will import into WordPad 5.1, and if saved in WordPad, will then import into Word. They needed much editing, especially of tables, so much so that it might have been better to get a skilled person to type parts of the file from scratch.
I briefly looked at the PDFXchange Web site, but it didn't look as if it offered editing. Maybe I was in too much hurry. Next I tried Edvard's suggestion of Foxit PDF Editor
- three cheers
, it works very well by comparison to Acrobat 9. Editing still tends to be fiddly and time-consuming, but at least I can get what was wanted done. At the time of writing Foxit are still offering a 10% Thanksgiving promotion, reducing the cost from $99 to $89.
