<p>PURPOSE:To improve an efficiency of a replotting process of a segment concerning a marker by registering, changing and holding a segment developing list and a changing information list. CONSTITUTION:When a marker segment registering means 21 generates a registering request, the plotting position of the marker is registered on the segment, and based on this the marker is developed to the plural segment and registered. When a segment transforming/changing means 23 generates the transforming request by the means 21, a transformation matrix is registered on a segment state list 22, and when an attribute changing means 24 generates an attribute changing request toward the attribute to be set, the contents of a bundle table is changed. When a changing information holding means 26 holds the changing information based on the execution of the means 23 and the means 24 in the list and a segment replotting means 23 makes a request, the existence of the changing information list concerning the marker is confirmed and a process is executed. When the existence of the changing information list is confirmed by the means 29, a segment developing list changing means develops the maker into the plural segment again and updates the segment developing list.</p> |
