I'm searching for a way to replace text in a PDF with other by using itext7. I get lost in some PDF terms and classes.
I find a very simple example by itext authors, but it won't fit my needs, as my PDF are far more complex (actually are a newspaper).
My idea is to search for a specific text in the page and replace part of the text by others. It has to be in the same position.
One thing that I don't understood is this a complex task, but acrobat pro can edit the text boxes so easily. Why I cannot find a text object and change its value as acrobat does?
