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 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.

OPTIONS

       --page=pagespec
              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.

       --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 interpreted 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.
