<p>PURPOSE:To simplify an operation at the time of copying, by enabling only the data of a window area on a desired virtual screen to be printed out of virtual screens corresponding to plural windows. CONSTITUTION:A picture synthesis control part 93 in a hard copy control part 9 opens the gate of gate circuits 91a-91n corresponding to a window No. on which a flag is set on a synthesis control table 94. And only the data of the virtual screen whose gate is opened out of the virtual screens 5a-5n is outputted at every line, and an OR processing is applied on it, and it is written on one line buffer 92. The data is outputted at every line to a printer 10, and after the output of all of the lines being completed, hard copying is completed. In such a way, it is possible to generate a hard copy by segmenting and synthesizing an arbitrary and desired number of data of the window from a multiwindow displayed picture.</p> |
