DESCRIPTION

13       This manual page documents briefly the pdfresurrect command.
14
15       pdfresurrect is a tool for extracting/scrubbing  versioning  data  from
16       PDF documents.
17

OPTIONS

19       A summary of options is included below.
20
21       -w     Write the PDF versions and summary to disk.
22
23       -q     Display only the number of versions contained in the PDF.
24
25       -s     Scrub the previous history data from the specified PDF.
26
27       -i     Display the creator information from the specified PDF.
28

NOTES

30       The  scrubbing feature (-s) should not be trusted for any serious secu‐
31       rity uses.  After using this feature, please verify  that  it  in  fact
32       zero'd all of the objects that were of concern (those objects that were
33       to be zero'd).
34
35       This tool relies on the application reading the pdfresurrect  extracted
36       versions  to  treat  the  last  xref(cross-reference) table as the most
37       recent in the document.  This should typically be the case.
38
39       The verbose output, which tries to deduce the  PDF  object  type  (e.g.
40       stream,  page), is not always accurate, and the object counts might not
41       be 100% accurate.  However, this should not prevent the  extraction  of
42       the  versions.  This output is merely to provide a hint for the user as
43       to what might be different between the documents.
44
45       Object counts might appear off in linearized PDF  documents.   That  is
46       not truly the case, the reason for this is that each version of the PDF
47       consists of the objects that compose the linear portion of the PDF plus
48       all of the objects that compose the version in question.  Suppose there
49       is a linearized PDF with 59 objects in its linear portion, and  suppose
50       the  PDF  has  a second version that consists of 21 objects.  The total
51       number of objects in "version 2" would be 59 + 21 or 80 objects.
