<p>PURPOSE:To easily execute a handwriting input, and also, to make the contents of a window easily visible by displaying the window by rotating it to an arbitrary angle. CONSTITUTION:The information processor is provided with a central processing unit (CPU) 401, a storage device, an input device, a display memory (VRAM) 406 for storing display data, and a display device (LCD) 404 for displaying the contents of the VRAM 406, and displays simultaneously plural windows on the LCD 404. In this case, in a position of the VRAM 406 defined, based on window management information containing a coordinate of a display position of the window which is being displayed at present, display priority, and a coordinate for showing the part superposed to the other window, the display data of the window is stored. As for the window management information, it is furthermore allowed to have a rotational angle of the window to a reference line of a display screen of the LCD 404, and to the display data of the window, a coordinate transformation is performed by using this rotational angle, and thereafter, it is stored in the VRAM 406.</p> |
