when&nbsp;I&nbsp;using&nbsp;the&nbsp;example&nbsp;"Multi&nbsp;Geo&nbsp;Raster&nbsp;Layer"&nbsp;to&nbsp;load&nbsp;a&nbsp;Satellite&nbsp;map,&nbsp;and&nbsp;add&nbsp;a&nbsp;cache&nbsp;Mechanism&nbsp;in&nbsp;it.&nbsp;

I&nbsp;want&nbsp;to&nbsp;speed&nbsp;up&nbsp;the&nbsp;loading&nbsp;speed.

I&nbsp;konw&nbsp;that&nbsp;when&nbsp;there&nbsp;are&nbsp;cache&nbsp;picture&nbsp;exist,&nbsp;it&nbsp;will&nbsp;load&nbsp;the&nbsp;cache&nbsp;file,&nbsp;so&nbsp;the&nbsp;speed&nbsp;is&nbsp;acceptable.

but&nbsp;the&nbsp;problem&nbsp;is,&nbsp;there&nbsp;are&nbsp;gap/crack&nbsp;(usually&nbsp;are&nbsp;lines&nbsp;shape)&nbsp;between&nbsp;some&nbsp;loaded&nbsp;cache&nbsp;pictures,&nbsp;and&nbsp;in&nbsp;diffrent&nbsp;zoomlevel&nbsp;the&nbsp;gaps&nbsp;are&nbsp;in&nbsp;diffrent&nbsp;location.

&nbsp;

the&nbsp;cache&nbsp;code&nbsp;is:

FileBitmapTileCache&nbsp;fileBitmapTileCache&nbsp;=&nbsp;new&nbsp;FileBitmapTileCache(@"C:\temp",&nbsp;"TestDataCache");

LayerOverlay&nbsp;layerOverlay&nbsp;=&nbsp;new&nbsp;LayerOverlay();

//creat&nbsp;the&nbsp;SatelliteLayer&nbsp;using&nbsp;"Multi&nbsp;Geo&nbsp;Raster&nbsp;Layer"&nbsp;example

layerOverlay.Layers.Add(SatelliteLayer);

layerOverlay.TileCache&nbsp;=&nbsp;fileBitmapTileCache;

&nbsp;

&nbsp;

thanks!
