Hi Kai, there are several ways to look at it:
- is a value of 4294966971 permitted? - does something like <INT KEY="Ascent" VAL="1006"/> <INT KEY="CapHeight" VAL="716"/> <INT KEY="Descent" VAL="4294966971"/> make sense? For the first one it's a little unclear as one could argue that the integer data typeas it only states that this is a mathematical integer. There are som ehint about implementations: The (PDF 2.0) spec has this about it (Annex C - Architectural limits) "Integer values (such as object numbers) can often be expressed within 32 bits." The 1.7 spec has this (Annex C - Architectural limits) integer 2,147,483,647 Largest integer value; equal to 231 − 1. So from that perspective the values are too large. Do the values make sense? Looking at an Ascent of 1006 and the Descent of 4294966971 this would be a funny looking font. Same applies to the Lab color settings etc. So I think although one could make it work (e.g. by using long instead of int) in PDFBox I'm not sure that this is really something wanted. What are the values when you export the same data from Windows? As you are dealing with xml you could strip the data before doing the import as a solution for your case.
