PDFBox: How to detect the max length of a PDTextBox

[Akshay Rawat <pr...@akshay.cc>]

I'm working with an AcroForm which has a text field (PDTextBox) with a max length. How do I use PDFBox to detect the max length of this field.

Thanks for any help.

When a property is not directly accessible through the object's getters, it

that this property is found by accessing the "MaxLen" property (which maybe  
should be added as one of the constants of the COSName object).  
So you can use it like so (field1 is a PDTextbox object):  

field1.getDictionary().getInt("MaxLen");  

This will return -1 if the Maximum Length property is not set.
