Replace short text with long text

First of all I'm trying to do a simple search replace...

I have a placeholder in an existing PDF lest call it ##TextPart1

Now I do a replace of "##TextPart1" but need to replace it with a large text with no line breaks...

This works almost, since all the text is in one line, and no line breaks are made at the page margin..

This means that the text disappears outside the document.

I'm using the code from last reply in this Post :

Is there any way to get around this. Since I need to use Aspose for handling replacements in PDF template files if it is possible... And I have to see replacements as one liners for which automatic line break is occurring..

Thanks in advance.
