djvuextract - Extract chunks from DjVu image files.
djvuextract [-page=pagenum] djvufile
[chkid=filename]...
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) for related information.

and many others.
