Several Icons on the same IconLayer

[ventoline]

Is it possible to display several different Icons in the same layer?

iconAtlas: d => ( icons[treeFamilies.indexOf(d.properties.family)] )
doesnt work, or any randomly assigned texture

Read the documentation

I did, many times. there isn't anything on using an array of icons, and the examples don't provide it. My answer isn't in there unfortunately. Also a note on the documentation, the examples dont always compile and in some cases it feels incomplete.

Well I suggest you read the properties section. iconAtlas is a single image (if you choose the prepacked route). iconMapping defines where multiple icons can be located in that image. You specify which icons to render using getIcon.

thank you for your reply. I dont have a say in the route,i am given separate image files andneed attach them to the Icon.
This seems to work:

  new IconLayer({
        id: "trees",
      data: data2.features, 
      getIcon: d =>({ url:  icons[treeFam2Valid.indexOf(d.properties.family)],
     width: 128,
     height: 128,
     mask:true //needed for colors !!!
    }), 
      getPosition:  d => d.geometry.coordinates ,
      getSize: d => ((d.properties.CrownRad + 1) * 3 ),
      sizeScale: 1,
      sizeUnits : "meters",
      sizeMinPixels : 12,
      getAngle : d => (Math.random()*360 ),   
     
       getColor: d => (d.geometry.coordinates[1] < 43.6293  &&  d.geometry.coordinates[0] < -79.418)?  /* && d.properties.SP_CODE !== "DEAD" */ 
       [
        colors[treeTypes.indexOf(d.properties.tag)][0],
        colors[treeTypes.indexOf(d.properties.tag)][1], 
        colors[treeTypes.indexOf(d.properties.tag)][2],
        (selectedOption === "all") || (selectedOption === d.properties.family) ?  220: 20
       ] 
         : [0,0,0,0] 
       ,
         updateTriggers: {
          getColor: [selectedOption]
         },  
      })
