       pdftosrc PDF-file [stream-object-number]

DESCRIPTION
       If  only  PDF-file is given as argument, pdftosrc extracts the embedded
       source file from the first found stream object with  /Type  /SourceFile
       within  the  PDF-file and writes it to a file with the name /SourceName
       as defined in that PDF stream object (see application example below).

       If both PDF-file and stream-object-number are given as  arguments,  and
       stream-object-number  is  positive,  pdftosrc extracts and uncompresses
       the PDF stream of the object given by its stream-object-number from the
       PDF-file  and  writes  it to a file named PDF-file.stream-object-number
       with the ending .pdf or .PDF stripped from the original PDF-file name.

       A special case is related to XRef object streams that are part  of  the
       PDF  standard  from  PDF-1.5 onward: If stream-object-number equals -1,
       then pdftosrc decompresses the XRef stream from the PDF file and writes
       it  in  human-readable PDF cross-reference table format to a file named
       PDF-file.xref (these XRef streams can not be extracted just  by  giving
       their object number).

       In  any  case  an existing file with the output file name will be over-
       written.

OPTIONS
       None.

FILES
       Just the executable pdftosrc.

ENVIRONMENT
       None.

DIAGNOSTICS
       At success the exit code of pdftosrc is 0, else 1.

       All messages go to stderr.  At program invocation, pdftosrc issues  the
       current version number of the program xpdf, on which pdftosrc is based:

              pdftosrc version 3.01

       When  pdftosrc  was successful with the output file writing, one of the
       following messages will be issued:

              Source file extracted to source-file-name

       or

              Stream object extracted to PDF-file.stream-object-number

       or

              Cross-reference table extracted to PDF-file.xref

              Error: May not be a PDF file (continuing anyway)
              (more lines)
              Invalid PDF file

       There are also more error messages from pdftosrc for various  kinds  of
       broken PDF files.

NOTES
       An  embedded  source  file will be written out unchanged, i. e. it will
       not be uncompressed in this process.

       Only the stream of the object will be written, i. e. not the dictionary
       of that object.

       Knowing  which stream-object-number to query requires information about
       the PDF file that has to be gained elsewhere, e. g. by looking into the
       PDF file with an editor.

       The  stream extraction capabilities of pdftosrc (e. g. regarding under-
       stood PDF versions and filter types) follow  the  capabilities  of  the
       underlying xpdf program version.

       Currently  the generation number of the stream object is not supported.
       The default value 0 (zero) is taken.

       The wording stream-object-number has nothing to  do  with  the  `object
       streams'  introduced  by  the Adobe PDF Reference, 5th edition, version
       1.6.

EXAMPLES
       When using pdftex, a source file can be embedded into some PDF-file  by
       using pdftex primitives, as illustrated by the following example:

       \immediate\pdfobj
           stream attr {/Type /SourceFile /SourceName (myfile.zip)}
           file{myfile.zip}
       \pdfcatalog{/SourceObject \the\pdflastobj\space 0 R}

       Then  this  zip  file  can  be  extracted  from the PDF-file by calling
       pdftosrc PDF-file.

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