Text of bug report to adobe:
Steps to reproduce bug:
1. Assign border style width 3.0 to each field widget with Apache PDFBox
2. Open PDF with Adobe Reader
Border is not of width 3
Border should be of width 3. However if the same is done programmatically with 3 as an integer (i.e. 3 instead of 3.0) it works. However the PDF 32000 specification clearly tells that the width in the border style dictionary is a "number". It does not request an integer. See Table 166 – Entries in a border style dictionary.
Sadly I can attach only one file. Both files are also in this bug report:
The files are named
BorderWidthTest3.0float.pdf (attach here too)
BorderWidthTest3int.pdf (displays correctly)
I have observed this effect only for the attached file (from Garry Grosso in the user mailing list). The effect does not happen with Annotations.
