发明名称 EFFICIENT GENERATION OF STATIC BITMAPS
摘要 A method of generating a bitmap entails transmitting a request for map data from a computing device to a map server, the request comprising a location for a map, a height of the map, a width of the map, and an image format. The method further entails receiving the map data for the map in response to transmitting the request for map data, and generating the bitmap locally on the computing device. The method may also involve obtaining customized overlay map data for combining with the other map data to generate the bitmap.
