Topic: Adjusting annotation & text string position & widt

I am working on a program that process the following
1) PDF converted from Word format
2) One single text string which also has an annotation
associated with it.
The text string is basically just "Pattern" in this
case and is position at the central of the page.
The associated annotation can either be /Filespec
or /URI type.
The text string itself is also underlined because in
the original Word document, it's of Hyperlink type.
1) If the text string "Pattern" is replaced with a
different length (ie. longer or shorter )
string, what is the right way to work out the new
central position X coordinate position ? Is there
any PDF operator that does this already ?
2) Because the "underlining" effect of the text string
is also a result of the Hyperlink type in Word
document, how can I change that underlining length
in PDF ? I have kind of manuallyplayed around a bit
with the 're' operator following the text string and
was able to see the underlining shifts around a bit
but I have yet to understand properly how it can
be accurately calculated on the fly.
A snippet of the PDF file looks like the following:
% .... some other stuff up here ...
/TT6 1 Tf

0 0.216 0.596 sc
222.4 453.56 150.6 1.68 re

Can any PDF expert please offer some help here ?
Thanks in advance.
