Tilman Hausherr updated PDFBOX-2163:
------------------------------------
Attachment: PDFBOX-2163-029016.pdf
The attached file has this:
{code}
EI<NL>DB'Z[<TAB>8F
{code}
so the part after EI was considered as "not binary". So I have improved the
code once again, requiring that the "not binary" part (which I have set to 10
bytes now) must have 1-3 non space characters after the end of EI and space
characters. This is probably still not the end of it, the next step would be to
require that the non-space character sequence be a valid PDF operator. This was
done in rev 1613645 for the trunk and rev 1613646 for the 1.8 branch.

> This PDF

> has an exception because the end of an inline image is improperly detected.
> The stream looks like this:
> {code}
> BI
> /W 452
> /H 169
> /BPC 8
> /CS /RGB
> /D [0.0 1.0 0.0 1.0 0.0 1.0]

> EI Q
> {code}
> The inline images are handled in PDFStreamParser. This is tricky, we look for
> followup bin data to check that it isn't an EI in the middle, but here it
> isn't bin data, but ascii85 stuff. We also can't request that there be a LF
> before the EI, because I remember that I had a PDF at work created by a well
> known company that doesn't use it.
