Hello Bruno, congratulations for the best PDF library,
I develop a change in your library for add a background image to a sign
field in the layer n0 , the size of the image fit to the sign field.
It`s a simple change but the look of the sign field is better with a
background image, i think :-)
I send to you the patch files to to pass from 1.3 version to my version
and viceversa and if you considere a good change , add to your library.
Thanks for your attention.
 

Thank you for the code enhancement.
I forward your mail to the mailinglist as I don't have the time to 
integrate it rightnow.
This way it gets archived and it makes a good change to be added to 
iText 1.3.1.
best regards,
Bruno
