This book is for programmers who are familiar with Release 4 of the X Window System and want to know how to use the new features of Release 5. It is intended as an update for owners of Volumes 1, 2, 4, and 5 of the O'Reilly and Associates X Window System series, and provides complete tutorial and reference information on all new Xlib and Xt toolkit functions.

It includes:

• Overview of the R5 changes as they affect application programming.
• How to write an internationalized application---one that anticipates the needs of a language and culture other than English.
• How to use scalable fonts and the fonts provided by the new font server.
• How to get consistent color on any display by using the X Color Management System.
• Overview of PEX, the new three-dimensional graphics extension for X.
• Reference pages for all new and modified Xlib and Xt functions and Athena widgets.

Together with Volume 2 and Volume 5, owners of the Programmer's Supplement for Release 5 have a complete set of reference pages for the current X Consortium standards for Xlib and Xt.
