List of all members.


Detailed Description

Directory of all-in-one-file DjVu documents (also known as DjVm documents). This class can read and write the directory (table of contents, in other words) of a DjVm document. This table of contents lists all { files} included into the document, not { pages} like {DjVuNavDir} does. It is normally stored in the document inside { DIR0} chunk where { "0"} refers to the version number.

An object of this class can be created either as a result of the decoding of an existing DjVm file, or manually by calling the default constructor and adding later directory entries by means of {add_file}() function.

You normally will not want to create or decode this directory manually. {DjVmFile} class will do it for you.

DjVmDir0.h
Files #"DjVmDir0.h"# and #"DjVmDir0.cpp"# contain implementation of {DjVmDir0} class responsible for reading and writing the directory of a multipage all-in-one-file DjVu document (usually referred to as { DjVm} document.

This is { not} a navigation directory, which lists all the pages in a multipage document. The navigation directory is supported by class {DjVuNavDir}. This is the directory of a DjVm archive.
