# djvuextract(1)

Extract chunks from DjVu image files.

## NAME

djvuextract - Extract chunks from DjVu image files.

## SYNOPSIS

**djvuextract \[-page=***pagenum***\]** *djvufile* **\[***chkid***=***filename***\]...**

## DESCRIPTION

Program **djvuextract** extracts raw chunk data from a DjVu file *djvufile*. These chunks can then be re-assembled into DjVu files using program **djvumake**.

Option  **-page** can be used to specify a particular page. Otherwise the first page of the document is assumed. Each remaining argument specifies that the raw data  associated with all the chunks named *chkid* will be concatenated into the file named *filename*. Chunks named  **BG44** and  **FG44** are handled slightly differently: the program generates legal IW44 files instead of simply saving the raw data.

See the man page  [**djvumake**(1)](/djvumake/1.md) for related information.

## CREDITS

This program was written by Léon Bottou \<leonb@users.sourceforge.net\> and was then improved by Andrei Erofeev \<andrew\_erofeev@yahoo.com\>, Bill Riemers \<docbill@sourceforge.net\> and many others.
