Detailed Description

The cross-reference table contains information that permits random access to indirect objects within the file so that the entire file need not be read to locate any particular object.

Cross-reference streams provide the following advantages:

• A more compact representation of cross-reference information
• The ability to access compressed objects that are stored in object streams (see section 7.5.7 - Object Streams) and to allow new cross-reference entry types to be added in the future

For more details please visit section 7.5.4 - Cross-Reference Table and section 7.5.8 - Cross-Reference Streams.
