Please see my most recent reply to Leonard's comments. This should help you
understand the issues that are involved. In the text-extraction procedure I
outlined earlier, I used Reader to produce the PS file from the PDF, thus
skirting around the issues you have.
You should also be aware that use of the text-extraction procedure I outlined
using the procedure would not be permissible if you contemplate using it for a
protected PDF, i.e., one that has protections enabled that you would be
circumventing by using the procedure.
Now, to your problem. You are trying to extend the text-extraction procedure
outlined earlier in this thread to text editing. Please heed Leonard's advice
that editing the text of a PDF is a very bad idea, together with my advice that
if you insist on editing a PDF, you should be prepared to repair the damage
that you do to it.
In another thread, I outlined a procedure for editing a PDF which is known to
work. If you wish to develop your own procedure, please feel free to do so. The
path you are on right now, however, is not likely to be successful.
Best regards,
Bill Segraves

Hello,
I am sorry if I am digressing. I have a bunch of PDF files in which I just want
to blank out the text. As I read the threads of this particular post, I got an
idea of replacing any textby doing this
(SOME TEXT) Tj to ( ) Tj
But when I converted my pdf file to ps using pdf2ps, I did not see any of such
structures. Still the ps file could be viewed using ghostscript viewer. I dont
know if my PDF is encoded in some sense. Is there any other way text is
rendered in ps?
I have attached my original PDF and converted PS file for your reference.
Sorry if it sounds very naive. I am pretty new to this whole thing.
Thank you,
Sarath
