Abstract
An apparatus for filling an interior of a shape to be displayed on a raster scan CRT which reads out a refresh memory. The apparatus includes a memory for storing information of starting points and ending points for filling. The write of a filling color code into the refresh memory is initiated and terminates in response to the filling starting point and the filling ending point, respectively, but inhibited at its memory locations on the contour of the shape. The direction of the filling is perpendicular to the raster scanning of the CRT.
