<p>PURPOSE:To easily select objects which overlap with one another by an editor for OA by indicating top display priority by an input part such as a mouse, and making a display attribute transparent and displaying respective areas independently. CONSTITUTION:Plural transparent image planes (areas 1-3) which are exactly equal in position and size are displayed on a CRT 3 one over the other. When one of them is selected as an object, click operation is performed on the input part of the mouse 6 to start the editor in a control program memory 2 and the display attribute of the area A is made opaque temporarily by an area control part to make a picture plane display. Consequently, only one area is displayed, so the operator starts operation when the displayed area is the target object. When not, the click operation is performed on the mouse input part again to give the top display priority to the area 2, whose display attribute is made opaque, so that only the area 2 is displayed. This operation is repeated until the target object is displayed.</p> |
