Hello.
I have noticed with PDFDebugger that the same pdf is rendered differently by
pdfbox-2.0.4 and by pdfbox-2.0.5 (pdfbox-2.0.6 produces the same output than
pdfbox-2.0.5): the newer versions generate a more pixelated image.
Please find attached a sample pdf and two screenshots of PDFDebug
ck the "Download" button)

"PDFDebugger" in your first post,
but you meant PDFToImage. It does happen as described. The images are
created with 120 dpi here, probably 96 dpi on your system.
I have no idea why, but I'll investigate it and come back to you.

Thanks Andreas. It doesn't seem to solve the issue but it may help. I'm a
newbie in the maven world, so, sorry if I misundestood something.
I have been trying to exclude the pdfbox dependency in fop (with the

I have used the modified XMPSerializer according to your advice and that solved

ecause you can't share your file. If you have a lot of time, try with
different versions from the repostory, i.e. a "bisect" strategy. It
takes hours, and is a work for patient people.
