Description SaGS 2005-08-24 13:49:16 UTC 
There are 2 main types of xref tables: the "classic xref" available in all 
PDF versions, and "xref streams" available in PDF1.5+. There is also a mix 
in the form of "hybrid-reference PDFs". For the latter, GS ignores the 
xref-stream part, beheaving as a PDF1.4-and-earlier viewer, even it does 
handle both main types of xref.

Comment 2 Dan Coby 2005-08-26 16:50:50 UTC 
Please attach a sample file.
Comment 3 SaGS 2005-08-26 23:29:23 UTC 
See the sample for bug 688283 "'trailer' without 'startxref'".

Notes:
- There's extra trouble with that file, which compounds the problem 
  described here (patch attached on that bug report).
- For that file, only structure information is hidden from PDF1.4 viewers, 
  so don't expect to see any difference by displaying/printing the file. 
  I stumbeld against this while fixing pdfinflt.ps (and there you will 
  see the difference).

This was not assigned correctly.
Comment 5 Alex Cherepanov 2008-01-01 13:59:41 UTC 
The patch is adopted and committed as a rev. 8473.
Thank you, SaGS.

Regression testing shows no differences.
