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 inputdjvu-
     file  and prints it into file outputtxtfile or on the standard output.  The
     hidden text layer is usually generated with the help of an optical  charac-
     ter 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  repre-
     sent 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.
