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:
“The public, with its mob yearning to be instructed, edified and pulled by the nose, demands certainties; it must be told definitely and a bit raucously that this is true and that is false. But there are no certainties.”
—H.L. (Henry Lewis)
“Unless, governor, teacher inspector, visitor,
This map becomes their window and these windows
That open on their lives like crouching tombs
Break, O break open,”
—Stephen Spender (1909–1995)
