23.4.18 SMOOTHING
To improve the appearance of the display, the SAA56xx
family of devices incorporates a smoothing algorithm to
insert extra pixels for all character sizes other than normal
size (see Fig.34). Smoothing is available in both TXT and
CC modes.
MMR 87E4H bit 4 enables smoothing in single page mode
and for Page A in double window mode. MMR 87E4H bit 5
enables smoothing for Page B in double window mode.
The appearance of special graphics characters and
fringed characters cannot be improved with the smoothing
algorithm.
