A system and method for automatically spacing characters by an output device, such as a printer or printing press onto a medium. The automatic spacing process utilizes kerning pairs and associated kerning values as input and results in an output of characters onto a medium having a desired amount of white space or "color" associated therewith. |

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION While the present invention may advantageously be implemented on nearly any conventional data processing system, exemplary data processing system 1500 on which the present invention is implemented is shown in FIG.
15.
FIG.
15 illustrates a preferred embodiment of hardware system 1500 implementing the present invention as part of a data processing system.
In FIG.
15, system 1500 includes CPU 1501, main memory 1502, video memory 1503, keyboard 1504 for user input, supplemented by conventional mouse (or light pen, electronic pen and data tablet, etc.
) 1505 for manipulating graphic images and mass storage 1506 which may include both fixed and removable media using any one or more of magnetic, optical or magneto-optical storage technology or any other available mass storage technology.
These components are interconnected via conventional bidirectional system bus 1507.
Bus 1507 contains address lines for addressing any portion of memory 1502 and 1503.
System bus 1507 also includes a data bus for transferring data between and among CPU 1501, main memory 1502, video memory 1503, mass storage 1506 and input/output (I/O) port 1511.
In the preferred embodiment of system 1500, CPU 1501 may be any suitable microprocessor or microcomputer.
I/O port 1511 enables system 1500 to have access to the "outside world" (e.
g.
, external systems, processes and printer 1512 and printing press 1513).
Main memory 1502 of system 1500 is a conventional dynamic random access memory of suitable size.
Video memory 1503 is a conventional dual-ported video random access memory.
Connected to a port of video memory 1503 is video multiplex and shifter circuitry 1508, to which in turn is connected video amplifier 1509.
Video amplifier 1509 drives cathode-ray tube (CRT) raster display monitor 1510.
Video multiplex and shifter circuitry 1508 and video amplifier 1509, which are conventional, convert pixel data stored in video memory 1503 to raster signals suitable for use by display monitor 1510
