X Bit Map
In computer graphics, the X Window System uses X BitMap (XBM), a plain text binary image format, for storing cursor and icon bitmaps used in the X GUI.
XBM files differ markedly from most image files in that they take the form of C source files. This means that they can be compiled directly into an application without any preprocessing steps, but it also makes them far larger than their raw pixel. Each byte of image data would be written in the C hexadecimal notation, '0x13' for example, using 4 bytes to express a single byte of image information.
