> We try to read text from PDF files but some of the files include extra data
> that is never shown. These segments are usually grouped in transparency
> groups. So for us this function to flag a marked content as a transparency
> group is quite useful.
> If there is a way to do this please tell me or if there is a better way to
> remove text that isn't presented or drawn when the PDF is viewed then I'm all
> ears.
