That's a good point... we know the device transform (it's the "xform"
variable), so we can certainly take it into account if needed. I'll test it out.
*Update*: Yes, you were right, I added some code to draw the clipping
rectangles and they were getting larger and larger at higher DPIs. I've updated
my patch to take the DPI into account.

> In case of a PDF file that was created with FOP 1.0 and was printed with
> PDFBox, lines disappeared or lines appeared smaller. PDF files that were
> created with Adobe InDesign (e.g.) will be printed correctly.
> It has something to do with lines which are part of a clipping mask. FOP
> seems to generate a clipping mask around all kind of borders. Lines of type
> <fo:leader> appear correctly and are not part of an clipping mask.
> When printing a FOP-PDF with PDFBox, PDFBox moves the clipping mask, so the
> line is not visible anymore. Please see attached Screenshot.
> The PDF file I created with FOP is named: original.pdf
> The resulting PDF file after printing with PDFBox is named:
> after_printing_with_pdfbox.pdf
> Regards
> Christoph
