Flex : opaque background color for a layer

carinestolz — Thu, 21 Apr 2011 09:26:14 GMT

Hi everyone !

I would like to add a layer (graphicsLayer for example) to my map with an opaque background instead of a transparent background. That layer would overlay the basemap and the basemap would not be visible anymore.

Is that possible with the ArcGIS flex API ?

Many thanks for your help !

Setting opaqueBackground on the GraphicsLayer won't cover the whole map with the color. Instead you can turn off the base layer and set opaqueBackground on the Map.

Try making these changes to this sample:

1. Set the id on the ArcGISTiledMapServiceLayer.
2. Add these lines of code to addSomeMarkers():
tiledLayer.visible = false;
myMap.opaqueBackground = 0xFF0000;
