       djvutxt - Extract the hidden text from DjVu documents.


       djvutxt [options] inputdjvufile [outputtxtfile]


       Program  djvutxt  decodes  the  hidden  text  layer  of a DjVu document
       inputdjvufile and prints it into file outputtxtfile or on the  standard
       output.  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
       describing the text and its  location.   Option  -escape  uses  C-style
       escape sequences to represent nonprintable non-ASCII characters.


              Specify  which  pages  should be processed.  When this option is
              not specified, the  text  of  all  pages  of  the  documents  is
              concatenated  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.

              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
              interpreted as char.

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


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


       This    program    was    initially    written    by   Andrei   Erofeev
       <>  and  was   then   improved   Bill   Riemers
       <> and many others. It was then rewritten to use
       the ddjvuapi by Leon Bottou <>.
