djvutxt(1)                       DjVuLibre-3.5                      djvutxt(1)




NAME

       djvutxt - Extract the hidden text from DjVu documents.



SYNOPSIS

       djvutxt [options] inputdjvufile [outputtxtfile]



DESCRIPTION

       Program djvutxt decodes the hidden text layer of a DjVu document input-
       djvufile and prints it into file outputtxtfile or on the standard  out-
       put.   The  hidden  text layer is usually generated with the help of an
       optical character recognition software.

       Without options -detail and -escape, this program  simply  outputs  the
       UTF-8  text.  Option -detail cause the output of S-expressions describ-
       ing the text and its location.   Option  -escape  uses  C-style  escape
       sequences to represent nonprintable non-ASCII characters.





OPTIONS

       --page=pagespec
              Specify  which  pages  should be processed.  When this option is
              not specified, the text of all pages of the  documents  is  con-
              catenated into the output file.  The page specification pagespec
              contains one or more comma-separated page ranges.  A page  range
              is  either  a  page  number,  or two page numbers separated by a
              dash.  For instance, specification 1-10 outputs pages 1  to  10,
              and specification 1,3,99999-4 outputs pages 1 and 3, followed by
              all the document pages in reverse order up to page 4.

       --detail=keyword
              This options causes djvutxt to output  S-expressions  specifying
              the  position  of  the  text  in  the page.  See the manual page
              djvused(1) for a description of  the  output  format.   Argument
              keyword  specifies  the  maximum  level of detail for which text
              location is reported.  The recognized values are: page,  column,
              region, para, line, word, and char.  All other values are inter-
              preted as char.

       --escape
              Output escape sequences of the form  "ooo" for all non ASCII  or
              non  printable UTF-8 characters and for the backslash character.






REMARKS

       Use program djvused(1) for more control over the text layer.
