The XPM format allows the user to also use letters instead of . A JPEG JFIF file is made up of a header which identifies the height, width, and depth of the image.

A basic X program opens a connection to the display, creates a window, maps the window, and processes events.
X provides several macros that define the data types of variables.
For the sake of brevity the example below does not provide X event processing. X Events X events consist of the pressing and releasing of keyboard keys and mouse buttons, movement of windows via the window manager, exposure of a window if it has been raised, notification that a window has been resized, and notification that the window manager requests that the window should close. The program must specify what events it wants to know about. Code A working example and a makefile can be downloaded . Thank you Marcus Meisinger, John Bradley, and Srinivas Vanjari for your help.
