    I've read the many threads here on iannotate and on PDF Expert and I remain unsure about the following: Can I use the "free form" highlight tool to mark "text" even though it is not technically "text" in that it is a scanned .jpeg converted to a .pdf?

    In Acrobat Professional you have to OCR these documents to turn the "scan" into true "text". Can't do that on the iPad.

    Will all of the other annotating tools work on a non-text .pdf?

    Thanks in advance.

    Works fine in PDF Expert.

    Can't say whether "all" apps do this, but I'd expect most would handle it fine.

    Answering My Own Question

    I bought iAnnotate, yesterday, and after a day of using it I'm very pleased.

    As to my specific question, the ability to annotae a non text .pdf:

    You can "paint" over the "text" and, thereby, turn it yellow.

    However, to use the highlighting tool, you must have a text document.

    My quick fix was to us Acrobat Pro, on my MBP, to OCR the scans to turn them to text and then transfer the documents to my iPad. It was quick and easy.

    After a day, I'm really liking iAnnotate but can't say I've pused the boundaries.

    Also, I note that in the "advanced" section there is the ability to turn on some "beta" functions that may deal with document conversion. I'm in the middle of "real" work and don't want to experiment. However, I will in the future.

    iannotate is pretty robust. it does not, however, ocr files (as far as i know). the advanced settings do different things.

    if you do a lot of scanning (receipts, records, articles, books, etc.) then i think you'll get your money's worth out of adobe acrobat pro. it does ocr quick and efficiently in multiple languages. converting a pdf to text enables you to utilize some of the most powerful features of iannotate, including its ability to do a global search (search every pdf at once for words and phrases).

    With PDF Forms application you can use Free Paint option ant thus annotate "non-text" .jpeg files.
