SYNOPSIS

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