Abstract: Methods are proposed for visually evenly spacing of two successive characters taking into account outline shape modifications induced by character grid-fitting. Visually even spacing of characters is obtained by converting the geometric space between two characters into its visually perceived equivalent space. Converting between geometric and visually perceived spaces requires transformations applied to the character outlines for smoothing out the character borders and replacing them by virtual borders which represent the boundaries of the perceived intercharacter space. The optimal visual distance between the origins of two successive characters is obtained by requiring the characters to have a perceived visual space equal or close to an ideal perceived visual space called ideal optical intercharacter space extracted from by design optimally spaced character pairs such as "nn" for lower-case characters and "HH" for capital letters.

Abstract: The present invention concerns a parallel multiprocessor-multidisk storage server which offers low delays and high throughputs when accessing and processing one-dimensional and multi-dimensional file data such as pixmap images, text, sound or graphics. The invented parallel multiprocessor-multidisk storage server may be used as a server offering its services to a computer, to client stations residing on a network or to a parallel host system to which it is connected. The parallel storage server comprises (a) a server interface processor interfacing the storage system with a host computer, with a network or with a parallel computing system; (b) an array of disk nodes, each disk node being composed by one processor electrically connected to at least one disk and (c) an interconnection network for connecting the server interface processor with the array of disk nodes.
