I haven't actually used this product yet (but I am going to try out the trial version).
I received a special off from VCOM today to purchase at half price (~$50) see here
From what I can see from web reviews and its own website it looks like a really comrephensive toolset for PDF files. It isn't just a 'printer driver' to generate PDF files but rather a workflow soltuion to PDF creation and modification and includes features such as PDF form design.
You can see the full product details here: nitroPDF
There are some interesting reviews too try here
(half way down).
NitroPDF seems to do just about everything the full version of Acrobat 7 does and then some.
Here are some of the more interesting things you can do to PDF files:
# Mark up and review documents. Add feedback to PDFs with the full range of PDF commenting tools: note, text box, text highlight, text cross-out, text underline, pencil, eraser, rectangle, line, oval, polygonal line, polygon and cloud. Modify comment color, position, author, subject and opacity, and lock or unlock position.
# Include files as attachments. Include any external file in an existing PDF document as an attachment. For example, attach audio files to PDF documents, or use a microphone to record audio comments directly.
# View and edit document properties. View title, author, subject, keywords, creator, producer, PDF version, number of pages, base URL and file optimization information; modify title, author, subject and keywords.
# Add custom metadata. Add an arbitrary number of additional metadata fields and values to a PDF.
# Search collections of files. Search entire folders of PDF documents, or search all PDF files on the computer. Searches for a text string in any combination of full text, bookmarks, comments, author, title, subject, keywords, creator, producer, creation date and modification date.
# Index collections of files. Create indexes of PDF documents for faster searching. Use advanced search tools: choose to match whole words or use stemming, and use Boolean logic.
