KB10688 - I have implemented the mini map sample code in my DK application but it is very slow to redraw and move the mini map cursor because the layer used in the MiniMap window is very large.

If a huge map file is used for the MiniMap, this can make the application run slow. Therefore, best is to present a file in the MiniMap which is relatively small. The easiest solution for this is to simply export a small raster file (adjust the compression and resolution to make the raster file relatively small) and present the small raster file in the MiniMap window. The use of a small vector file which presents only the major map features - such as the boundaries of the project extent - also works well. Because the Mini-Map window is small and not used to preset zoomed-in views, it makes no sense to present a very detailed (large) map file in that window.
