The invention allows digital information to control a graphics display in which the reproduction of sloping and curved lines is enhanced. Video data from memory (12) is processed by circuitry (14) and serialiser (16) to form a serial video signal. Each pixel can be moved by a fraction of a pixel width by delaying the shift signal to serialiser (16) under the control of attribute data for that pixel stored in memory (12). One form of delay means is the tapped delay line (24) and multiplexer (26) shown. |
