Tilman Hausherr updated PDFBOX-2401:
------------------------------------
    Description: 
Marc Davis fronm the user mailing list has provided a file (michael levine.pdf) 
that, when merged with another file, has a black image on page 17 ("TL-9"). I 
tried to investigate / narrow this somewhat:
- it happens with any other file, or just use the michael levine file twice
- extracting p17 with PDFSplit doesn't do it
- extracting p1-17 with PDFSplit does do it
- extracting p13-17 with PDFSplit does do it, altthough the black is now at the 
first page

The page is not really "black", the colors are incorrect.

That's all I found out until now. I compared the two files with PDFDebugger and 
can't see any obvious differences. I looked into the files with NOTEPAD++, 
there are some differences like that the colorspace is now indirect.
