This function scans the indicated point or area on the specified map, and sets the bit corresponding to each color value found correspondingly. For example, if scanning map 4 (special) would touch two areas, one with color value 1 and one with color value 10, the resulting return value would be 0x0402 (binary 0000010000000010).
