NAME

6       pdftosrc - extract source file or stream from PDF file
7

SYNOPSIS

9       pdftosrc PDF-file [stream-object-number]
10

DESCRIPTION

12       If  only  PDF-file is given as argument, pdftosrc extracts the embedded
13       source file from the first found stream object with  /Type  /SourceFile
14       within  the  PDF-file and writes it to a file with the name /SourceName
15       as defined in that PDF stream object (see application example below).
16
17       If both PDF-file and stream-object-number are given as  arguments,  and
18       stream-object-number  is  positive,  pdftosrc extracts and uncompresses
19       the PDF stream of the object given by its stream-object-number from the
20       PDF-file  and  writes  it to a file named PDF-file.stream-object-number
21       with the ending .pdf or .PDF stripped from the original PDF-file name.
22
23       A special case is related to XRef object streams that are part  of  the
24       PDF  standard  from  PDF-1.5 onward: If stream-object-number equals -1,
25       then pdftosrc decompresses the XRef stream from the PDF file and writes
26       it  in  human-readable PDF cross-reference table format to a file named
27       PDF-file.xref (these XRef streams can not be extracted just  by  giving
28       their object number).
29
30       In  any  case  an existing file with the output file name will be over‐
31       written.
32

OPTIONS

34       None.
35

FILES

37       Just the executable pdftosrc.
38

ENVIRONMENT

40       None.
41

DIAGNOSTICS

43       At success the exit code of pdftosrc is 0, else 1.
44
45       All messages go to stderr.  At program invocation, pdftosrc issues  the
46       current version number of the program xpdf, on which pdftosrc is based:
47
48              pdftosrc version 3.01
49
50       When  pdftosrc  was successful with the output file writing, one of the
51       following messages will be issued:
52
53              Source file extracted to source-file-name
54
55       or
56
57              Stream object extracted to PDF-file.stream-object-number
58
59       or
60
61              Cross-reference table extracted to PDF-file.xref
62
63
64       When the object given by the stream-object-number does  not  contain  a
65       stream, pdftosrc issues the following error message:
66
67              Not a Stream object
68
69       When the PDF-file can't be opened, the error message is:
70
71              Error: Couldn't open file 'PDF-file'.
72
73       When  pdftosrc  encounters an invalid PDF file, the error message (sev‐
74       eral lines) is:
75
76              Error: May not be a PDF file (continuing anyway)
77              (more lines)
78              Invalid PDF file
79
80       There are also more error messages from pdftosrc for various  kinds  of
81       broken PDF files.
82

NOTES

84       An  embedded  source  file will be written out unchanged, i. e. it will
85       not be uncompressed in this process.
86
87       Only the stream of the object will be written, i. e. not the dictionary
88       of that object.
89
90       Knowing  which stream-object-number to query requires information about
91       the PDF file that has to be gained elsewhere, e. g. by looking into the
92       PDF file with an editor.
93
94       The  stream extraction capabilities of pdftosrc (e. g. regarding under‐
95       stood PDF versions and filter types) follow the capabilities of the un‐
96       derlying xpdf program version.
97
98       Currently  the generation number of the stream object is not supported.
99       The default value 0 (zero) is taken.
100
101       The wording stream-object-number has nothing to  do  with  the  `object
102       streams'  introduced  by  the Adobe PDF Reference, 5th edition, version
103       1.6.
104

EXAMPLES

106       When using pdftex, a source file can be embedded into some PDF-file  by
107       using pdftex primitives, as illustrated by the following example:
108
109       \immediate\pdfobj
110           stream attr {/Type /SourceFile /SourceName (myfile.zip)}
111           file{myfile.zip}
112       \pdfcatalog{/SourceObject \the\pdflastobj\space 0 R}
113
114       Then  this  zip  file  can  be  extracted  from the PDF-file by calling
115       pdftosrc PDF-file.
116

BUGS

118       Not all embedded source files will be extracted, only the  first  found
119       one.
