System and method for rotating font data and map display system for displaying rotated font data

摘要

Systems, methods, and programs for rotating font data may store font data and a plurality of conversion tables, each conversion table corresponding to a preset rotational angle. The systems, methods, and programs may select one of the conversion tables in accordance with a required angle and may rotating the font data based on the selected conversion table. The systems, methods, and programs may further store map data. The systems, methods, and programs may generate name designations of display objects included in the map data in accordance with an arrangement of the display objects on a map and may determine the required angle in accordance with the arrangement of the display objects on the map. The systems, methods, and programs may rotate characters of the generated name designations according to the required angle to create rotated name designations and may display the map data including the rotated name designations.
