DJVUDUMP(1) DjVuLibre-3.5 DJVUDUMP(1)NAME
djvudump - Display internal structure of DjVu files.
SYNOPSIS
djvudump djvufiles...
DESCRIPTION
Program djvudump prints an indented representation of the chunk structure of any DjVu files. Each line represent contains a chunk ID fol-
lowed by the chunk size. Lines are indented in order to reflect the hierarchical structure of the IFF files. The page identifier is
printed between curly braces when a bundled multi-page DjVu document is recognized. Additional information about each chunk is provided
when djvudump recognizes the chunk name and knows how to summarize the chunk data.
REMARKS
This program is in fact able to describe any file complying with the Electronic Arts IFF 85 specification. This includes a number of
graphical and sound file formats.

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 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 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 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.
