Embodiment Construction
[0014] Embodiments of the present invention provide a method and device for smooth map movement, which are used for map display in a navigation system, so that the map can move smoothly.
[0015] see figure 1 , which is an embodiment of a method for smooth map movement in the embodiment of the present invention, including:
[0016] 101. Acquiring the range of the map to be drawn on the current display interface in real time;
[0017] When the map is being moved, the system will obtain the range of the map to be drawn on the current display interface in real time.
[0018] 102. Determine whether the range of the map to be drawn is in the preset reference bitmap, if so, execute step 103, if not, execute step 104;
[0019] In the embodiment of the present invention, the system will preset a reference bitmap, which is a drawn map that exists in the form of a bitmap, and the reference bitmap is cached in the system, and there is no need to load and store data when using it. The ...
