Change PDF form field font
Use iText to change the font of interactive form fields in a PDF.
Changes the font in 'f1040.pdf' to Courier.
This code is based on the following example from iText:

For now I just downloaded the dependencies' JAR files and put them in a
'lib/' directory rather than have to learn how to use a dependency
management tool like Maven. Here is the contents of the 'lib/'
directory:
barcodes-7.2.2.jar
commons-7.2.2.jar
font-asian-7.2.2.jar
forms-7.2.2.jar
hyph-7.2.2.jar
io-7.2.2.jar
kernel-7.2.2.jar
layout-7.2.2.jar
pdfa-7.2.2.jar
pdftest-7.2.2.jar
sign-7.2.2.jar
slf4j-api-1.7.9.jar
styled-xml-parser-7.2.2.jar
svg-7.2.2.jar
To run this:
$ make
$ make run
