X PixMap （XPM）是一种基于ASCII编码的图像格式，在X Window系统中的应用十分广泛。她最初由位于法国Sophia Antipolis的Bull研究中心的Daniel Dardailler和Colas Nahaboo发明，后来Arnaud Le Hors对其进行了改进。XPM文档经常用于创建图标位图文档，支持“transparent color”功能。XPM文档格式源自更早的X BitMap（XBM）。特点是文档格式简单，可以被任何文本编辑器创建和修改，另外通过#include指令可以将XPM格式的图形数据导入C语言源文档，这对进程员而言有时是十分方便的。

X PixMap (XPM) is an image file format used by the X Window System, created in **** by Daniel Dardailler and Colas Nahaboo working at Bull Research Center at Sophia Antipolis, France, and later enhanced by Arnaud Le Hors.

It is intended primarily for creating icon pixmaps, and supports transparent pixels. Derived from the earlier XBM syntax, it is a plain text file in the XPM2 format or of a C programming language syntax, which can be included in a C program file.
