The fields don't have to be editable after the user saves. If it's not too
much could someone provide me the steps of doing this? I am not looking for
an entire program but just the methods in the correct order to do this.
Even the reference to the book would be good.
So far all I understand is that I would have to get some information from
the field (using which methods?), flatten it (which methods?), then use
showTextAlignedKerned() . But where do I actually give the kern values?
Thank you,
