A content stream is just a stream so if you overwrite that one, you're done.
Unless of course other things need to be changed, e.g. resources.

Hi Tilman,
yes the stackoverflow request is also from me - the issue I have is how to
replace the stream inside the form. I have no form.setContentStream() function.
Besides I'm no sure if the getContentStream() returns the whole PDFormXObject.
Best regards,
Bernward

You can call getStream() on the PDFormXObject and then change that one, or are
you asking something different?

is also from you?
Or is your question about replacing a form in the resources?

Dear all,
I'm struggling with replacing text within a Form. I detect the text I can
replace it, but putting it back to the form seems to be the hell on earth.
What was my approach?
I'm using MKL's PdfContentStreamEditor (Thanks for that it was a very
useful starting point) Replacing content within the main content is
quite easy with that (Replacing all changed Tj with TJ by the way)
I think the purpose of doing nothing in the showForm overwrite is exactly to
avoid replacements in Forms.
So creating a new outstream for the form and putting my redactions there is
also done (text is found and replaced).
But how to replace the old form stream with the new one?
Thanks a lot,
Bernward
