I have found in sdk api the following method:
PDWordFinderAcquireVisibleWordList()
"Finds all words on the specified page that are visible in the given optional-content context" what does it means 'visible'? it is related with the 'heuristic' Acrobat uses to show 'hidden text'?
It is not clear also the 'PDOCContext ocContext' parameter this method uses.
Thanks
