This is what I need to do.
I am displaying the field names from a PDF as prompts in my application.
The user enters information, saves and then views the PDF file.
I need to give them the option to space out the text that was entered in
case they don't like they look of it. For example make wider spaces on
between characters and then preview again.
They may want to also change the font, color, position, etc which I see
there are methods to do that.
Basically I am looking for something like a pseudo method
setFieldKerning("Name",pos1, pos2, kernValue)
How can i do this?
