NAME
pdfresurrect - tool for extracting/scrubbing versioning data from PDF
documents
SYNOPSIS
pdfresurrect file.pdf [-w][-q][-s][-i]
DESCRIPTION
This manual page documents briefly the pdfresurrect command.
pdfresurrect is a tool for extracting/scrubbing versioning data from
PDF documents.
OPTIONS
A summary of options is included below.
-w Write the PDF versions and summary to disk.
-q Display only the number of versions contained in the PDF.
-s Scrub the previous history data from the specified PDF.
-i Display the creator information from the specified PDF.
NOTES
The scrubbing feature (-s) should not be trusted for any serious
security uses. After using this feature, please verify that it in fact
zero’d all of the objects that were of concern (those objects that were
to be zero’d).
This tool relies on the application reading the pdfresurrect extracted
versions to treat the last xref(cross-reference) table as the most
recent in the document. This should typically be the case.
The verbose output, which tries to deduce the PDF object type (e.g.
stream, page), is not always accurate, and the object counts might not
be 100% accurate. However, this should not prevent the extraction of
the versions. This output is merely to provide a hint for the user as
to what might be different between the documents.
Object counts might appear off in linearized PDF documents. That is
not truly the case, the reason for this is that each version of the PDF
consists of the objects that compose the linear portion of the PDF plus
all of the objects that compose the version in question. Suppose there
is a linearized PDF with 59 objects in its linear portion, and suppose
the PDF has a second version that consists of 21 objects. The total
number of objects in "version 2" would be 59 + 21 or 80 objects.
