How to add MapImageLayer into BasemapGallery

[prashantk]

Hi All,

I want to display custom  basemap with overlay image so I am using "MapImageLayer" class to add layer on map. 

Apart from this I have two custom basemaps so, I used dojo BasemapGallery widget to display collection of basemaps.

Is there any way to add  "MapImageLayer"  into "BasemapGallery"  widget?

Any help would be appreciated

Thanks & Regards,

Prashant

Prashant,

Using a MapImageLayer is not supported. Your layer has to be cached and you have to use TileLayer at least.

Sure just load your cached layer as a basemap class:

Basemap | API Reference | ArcGIS API for JavaScript 4.7 

Then specify the BaseMapGallery widgets LocalBasemapsSource property

LocalBasemapsSource | API Reference | ArcGIS API for JavaScript 4.7
