<p>PURPOSE:To improve the efficiency of a trimming layout job by placing a designated point at the center position of a display picture and displaying partial picture data on a display device without interleaving. CONSTITUTION:An assignment board 5 is set on a data tablet 4, two points P1, P2 representing an origin O and a trimming range K, and a specific point P3 are inputted by designating them by a cursor 4A to write picture data on a memory. The data stored in the memory is not thinned out and displayed on a display device 6 as point symmery around a designated point P0 calculated for only a part of the picture corresponding to the specific point P3. The deviation between the designated point and the specific point P3' on the display device 6 is obtained, points P1' and P2' corresponding to the P1, P2 on the data in the memory are obtained and trimming layout is applied based thereupon.</p> |
