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 women of my mother’s generation had, in the main, only one decision to make about their lives: who they would marry. From that, so much else followed: where they would live, in what sort of conditions, whether they would be happy or sad or, so often, a bit of both. There were roles and there were rules.”
—Anna Quindlen (20th century)
“When I had mapped the pond ... I laid a rule on the map lengthwise, and then breadthwise, and found, to my surprise, that the line of greatest length intersected the line of greatest breadth exactly at the point of greatest depth.”
—Henry David Thoreau (1817–1862)
