How to modify a layer in a blueprint

threeooo — Sat, 08 Oct 2022 09:53:42 GMT

Can I edit a layer in a Blueprint? Like transparency, visibility, or adding and removing layers.

I tried using the Create Arc GisImage Layer with Properties function and it didn't work.

I don't know if I'm going in the wrong direction.

ArcGis->MapComponent->GetLayers,I can get an array, but I don't know how to convert each item to get the layer I want.

If you want to modify layers instead work with the layers list on the View. In other words MapComponent->GetView()->GetMap()->GetLayers

Get the Map Component, connect the Get Map() function, and use the GetLayers() function. At this point, we can get all the layers loaded. To get a specific layer, use the GetSize() function.

My method:

All layers: GetMapComponent() -> GetMap() ->GetLayers()

One layer: GetMapComponent() -> GetMap() ->GetLayers() ->At(Position)

I also have a problem: GetMapComponent() ->GetView()-> GetMap(), which can also get layers, so what the GetView() function does, I can't understand at the moment.

We will try to clean up the api so it is more obvious where it needs to be changed.
