List of all members.


Detailed Description

Implements DjVu multipage document directory. There are currently two multipage DjVu formats supported: {bundled} and {indirect}. In the first format all component files composing a given document are packaged (or bundled) into one file, in the second one every page and component is stored in a separate file and there is one more file, which contains the list of all others.

The multipage document directory lists all component files composing the given document, helps to access every file, identify pages and maintain user-specified shortcuts. Every directory record describes a file composing the document. Each file is identified by a small string named the identifier (ID). Each file may also contain a file name and a title.

The DjVmDir# class represents a multipage document directory. Its main purpose is to encode and decode the document directory when writing or reading the DIRM# chunk. Normally you don't have to create this class yourself. It's done automatically when {DjVmDoc} class initializes itself. It may be useful though to be able to access records in the directory because some classes (like {DjVuDocument} and {DjVmDoc}) return a pointer to DjVmDir# in some cases.
