Abstract: PURPOSE: To attain an automatic fill processing by counting the outlines of the plus and minus directions of a Y axis along an X axial direction, and assigning a closed block area in which a difference between the total number of the Y axial plus directions and that of the Y axial minus directions is turned 0 to an area not to be filled, and assigning an area in which that is not turned 0 to an area to be filled. CONSTITUTION: A CPU 10 checks the size relation of the Y axial coordinate values of two adjacent end point positions on a work memory 14, and decides the traveling direction of a segment connecting the two end point positions. When the segment moving from a first point to a second point is traveling to a Y axial minus direction, the relation that the Y axial coordinate value of the first point is more than the Y axial coordinate value of the second point is obtained, and when the segment is orthogonally crossing the Y axis, the two Y axial coordinate values are made equal. In this method, the traveling direction of the segment connecting each end point is analyzed, and data are divided into two kinds of data. That is, after graphic bit data and Y directional bit data are prepared, a fill picture is prepared on the exclusive area of the work memory 14.
