ABSTRACT:
An apparatus for generating a high-quality pattern comprises a code pattern memory for storing a plurality of first winding number (WN) codes, a projection section responsive to an input projection start command, for projecting at least one size change contour line of input size changed contour line data for defining an area of the pattern in the code pattern memory while updating the first WN codes with second WN codes determined in accordance with a drawing direction of the size changed contour line and a filling direction in units of dots representing the size changed contour line, and for generating a projection end response upon completion of projection of the size changed contour line, a filling section responsive to an input filling start command, for filling the area in accordance with the first WN codes read out from the code pattern memory obtain the pattern, and a controller for outputting the projection start command to the projection section in response to an input pattern generation instruction and for outputting the filling start command to the filling section in response to the projection end response.
