Abstract

The graphic system includes a framestore (21) and a pipeline brush processor (22). Image pixels are read out of the framestore in batches and applied to an input of the brush processor. Other data representing colour shape and pressure of a line drawn by a user on a touch tablet (17) by way of a stylus (18) is also input to the processor. As the pixels pass through the processor they are modified by the other data. Batches of modified pixels are written back to the framestore. The reading and writing of pixels from the framestore (21) is interleaved with the reading of pixels for display as an image on a monitor (16). The system also includes an arrangement for interpolating stylus pressure to remove visible discontinuities or other changes in the drawn image resulting from significant changes in stylus pressure.
