PURPOSE:To execute complicated enlargement processing without using an expensive graphic accelerator in respect of a data processor provided with an enlarging function for a displayed pattern. CONSTITUTION:In the data processor adopting such configuration as to display a pattern on a display by adopting the configuration to manage the shape data of the pattern, and generating the bit map data of the pat tern from the shape data, and developing it on a memory for display, it is constituted so as to be provide with a specifying means 13 which specifies coordinate information on the bit map data each dot of a pattern part to be an enlarged object has in the case that the enlarging request of the displayed pattern arises, a transforming means 14 which coordinate-transforms the specified coordinate information in conformity to a designated enlargement ratio, and a developing means 15 which displays the enlarged pattern of the pattern part requested to enlarge on the display by developing the bit map data determined by the transformed coordinate information on the memory for display. |
