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.
Famous quotes containing the words bit and/or map:
“A Bird came down the Walk—
He did not know I saw—
He bit an Angleworm in halves”
—Emily Dickinson (1830–1886)
“You can always tell a Midwestern couple in Europe because they will be standing in the middle of a busy intersection looking at a wind-blown map and arguing over which way is west. European cities, with their wandering streets and undisciplined alleys, drive Midwesterners practically insane.”
—Bill Bryson (b. 1951)
