I'm working with large sets (20,000+) of pushpins. When I map them using lat/lon and standard symbols that come with MapPoint the map runs quite smoothly. When I start using custom symbols the map becomes very very slow to scroll around. My custom symbols are as small or smaller than the built in symbols and i've tried several different file formats (.bmp, .cur, .ico etc..) without much success. Importing the pushpins is not my problem; my main concern is having a map that runs smoothly with a lot of custom symbols on it.
Is there a way to optimize my custom pushpins so that they get the same performance as the built in symbols? Is there a way to modify the standard symbol file? I'm familiar with VB and I'd be happy for a code based solution.
