Multiple Ground Overlays #319

Closed ham187 closed 4 months ago

ham187 commented 4 months ago

Hello, and thank you again,

I have a need for multiple ground overlays, and when the user moves the map it needs to redraw them, the problem is I can't clear the original ground overlay, so its just laying them over the top, until you can't see under it.

I tried adding them to a dictionary and then clearing them, but it doesnt work.

foreach(var go in dictofGroundOverlays) {
await go.Value.SetMap(null); }

any suggestions?

It should clear. Any console errors? If you do like in this demo does it get cleared? https://github.com/rungwiroon/BlazorGoogleMaps/blob/master/ServerSideDemo/Pages/MapGroundOverlayPage.razor.cs#L47

nope no errors, I'm adding satellite imagery to a map, which loads as you scroll around the map, and zoom in and out, but as you zoom out some layers overlap, as it can't remove the existing ones before redrawing,
