<p>PURPOSE:To facilitate the setting operation of a window by performing the parallel displacement of the window whose size is set, and setting it around a prescribed center rotatably. CONSTITUTION:At the time of moving the window WDW on a display picture DSP having a plotting coordinate system (v-h), the size of the window WDW is set in advance, and its center is moved to a designated position PC(hC, vC) first. Next, the parallel displacement of the window WDW is performed by a designated amount of travel DELTAh and DELTAv, and travel is completed by combining a processing to rotate by a designated amount of rotation DELTAtheta centering a prescribed point.</p> |
