PURPOSE:To make it possible to operate graphic processing devices virtually, by providing attribute converting means where individual graphic processing devices convert various attributes, which are determined by an attribute set table, to expressible attributes. CONSTITUTION:The attribute converting means is incorporated in each device control part 3 for the purpose of converting colors or the like, which are designated by the attribute set table, to the most approximate attributes which can be displayed on each individual graphic processing device. Values 0-225 of colors R, G, and B designated by a display color definition table are converted to ''0'' or ''1'' respectively, and an attribute conversion memory for a graphic display where 8 colors can be displayed in accordance with combinations of ''0'' and ''1'' is referred, and numbers 0-7 of attributes defined by this memory are obtained. Individual device control parts 3 designate attributes with these numbers to display graphics on graphic processing device. |
