How to Keep the order of boxes?

[Muhammadraafat1]

Hi, When I applied redaction and insert_text with the replaced word and save my output.pdf, I try by mouse to select line has original word next to replaced word, I found all pages in pdf was selected!

Here is an example:
this is original text: As you see it select what I already selected by mouse

Here I want to select only "To: PETER ADEL": PETER ADEL is replacement word.

There is anything to do with that?

This lies in the nature of PDF and cannot be avoided.
Text will always be selected (and extracted) in the sequence as physically stored in the page appearance program ("stream").

In case of redactions, this means that the evacuated space of the old text will not somehow be left as a gap in that appearance stream. The respective commands displaying old text will instead be deleted.
And the new text will be appended via program-like instructions to the end of that program.
Everything appears to be in nice order, because the new text carries coordinates instructing the PDF viewer to put it where intended.
