A system for converting vector data to pixel data to draw the vector on a display screen. The display screen is divided into groups of pixels (matrices) each having a certain number of pixels in the x and y directions. As the vector data for a given matrix is processed, the next matrix through which the vector extends is identified according to where the vector extends in relation to two decision points within the given matrix. If the vector is above a first one of such points, the next matrix is in the x direction, whereas if the vector is below the second one of such points the next matrix is in the y direction. If the vector extends between such points, the next matrix is one matrix away in both the x and y directions.
