Thank you for the reply.
I could store meta data about the fields’ capacity as a last resort. However,
there are about 50 different forms to work with and the number will continue to
grow.
Including Tilman’s reply here:
"Calculate the width of the /Rectangle. 1 unit = 1/72 inch.”
Are the /Rect coordinates represented in the following order?
Left rectangle boundary, Top, Right, Bottom
So, 91.095 - 51.855 = 39.24/72s inch wide (or a little over a 1/2 inch)??
And, how does one get to the /Rect data?
I have a debug session open in Eclipse but am not seeing the /Rect data in
ether the PDField or PDAcroForm.
