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
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 -s Scrub the previous history data from the specified PDF.
25
26 -i Display the creator information from the specified PDF.
27
29 The scrubbing feature (-s) should not be trusted for any serious secu‐
30 rity uses. After using this feature, please verify that it in fact
31 zero'd all of the objects that were of concern.
32
33 This tool relies on the application reading the pdfresurrect extracted
34 versions to treat the last xref(cross-reference) table as the most
35 recent in the document. This should typically be the case.
36
37 The verbose output, which tries to deduce the PDF object type (e.g.
38 stream, page), is not always accurate, and the object counts might not
39 be 100% accurate. However, this should not prevent the extraction of
40 the versions. This output is merely to provide a hint for the user as
41 to what might be different between the documents.
42
43 Object counts might appear off in linearized PDF documents. That is
44 not truly the case, the reason for this is that each version of the PDF
45 consists of the objects that compose the linear portion of the PDF plus
46 all of the objects that compose the version in question. Suppose there
47 is a linearized PDF with 59 objects in its linear portion, and suppose
48 the PDF has a second version that consists of 21 objects. The total
49 number of objects in "version 2" would be 59 + 21 or 80 objects.
