I asked a question on the list a few weeks back, which I will now ask
again in hopes that someone knows of a way to do this.
Is there any way using iText to develop a heuristic which detects PDFs
which have been improperly redacted in the below fashion? Ever if it
is not 100% reliable.
In other words, can I programatically identify PDF's where a
rectangle has been superimposed over text content?
Thanks,
