In typography, a computer font which is designed to be output in a wide variety of point sizes. Such fonts are described by the computer as a series of mathematical formulas describing lines, curves, and other shapes. When a new size is desired, it is a simple computation to recalculate the formula, creating the new size. Such fonts are said to be resolution-independent, as they can be output at the highest resolution the output device is capable of. Many bitmapped fonts, in contrast, are created using different images for different sizes. One advantage to the PostScript page description language is that it uses scalable fonts.
