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.
