Patent number: 8593477Abstract: A plurality of closed regions constituting a line drawing image are extracted and displayed on a display means. A desired closed region included among the plurality of displayed closed regions is extracted as an image layer by specifying the desired closed region by means of a manipulation means. At this time, a closed region display screen for displaying the extracted closed regions thereon and an image layer display screen for displaying the extracted image layer thereon are displayed in side by side relation on the display means. Thus, whether an appropriate closed region is converted to the image layer or not is easily determined. Also, when a plurality of closed regions are specified, the plurality of specified closed regions are extracted as an image layer. Thus, the plurality of closed regions are treated together as the single image layer.Type: GrantFiled: November 25, 2008Date of Patent: November 26, 2013Assignee: Dainippon Screen Mfg.
