DESCRIPTION

12       This manual page documents briefly the pdfresurrect command.
13
14       pdfresurrect  is  a  tool for extracting versioning data from PDF docu‐
15       ments.
16

OPTIONS

18       A summary of options is included below.
19
20       -w     Write the PDF versions and summary to disk.
21
22       -q     Display only the number of versions contained in the PDF.
23
24       -i     Display the creator information from the specified PDF.
25

NOTES

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