Description Michal Jaegermann 2002-10-24 23:36:42 UTC

Description of Problem:

I got recently a pdf file for which xpdf shows only blank pages.
'pdfinfo' shows the following information about it:

Tagged:       no
Pages:        6
Encrypted:    no
Page size:    612 x 792 pts (letter)
File size:    139423 bytes
Optimized:    yes
PDF version:  1.4

It is true that errors like that are generated

Error (0): PDF file is damaged - attempting to reconstruct xref table...

Neverthless quite old 'acroread' complains but still shows all
contents.

This is the same with xpdf-1.01-8 from RH 8.0 and xpdf-1.00-3 as current
in 7.3

I can provide that file if requested (at least if requested within
a reasonable time).

Comment 1 Ngo Than 2002-12-08 21:28:20 UTC

could you please provide this test file please? or please try xpdf-2.01 in
rawhide if it fixes this problem.

please reopen this bug, if it's not fixed in xpdf-2.01 in the rawhide.

Comment 2 Michal Jaegermann 2002-12-08 23:20:45 UTC

I had some exchange with Derek N., the author of xpdf, about the issue.
The problem is that fonts in the file in question are damaged and xpdf
parser, even in the current version, does not know how to handle the situation.
This may change in the future. Acroread, even pretty old one, indeed does
comes in that situation markedly better.

If you still desire the file which exhibits the trouble drop me a line.
