Maps: Understanding SymbolLayer

[arnaudambro]

I have a hard time trying to understand how the SymbolLayer works, especially the style prop, especially the properties iconSize and iconImage seen in the ShapeSourceIcon example.
I understand that there is a lot of WIP in this library, especially regarding the doc, and if I have some time I would be glad to help, but in the meantime I need to sort out my transition from PointAnnotation to SymbolLayer, and I feel it quite hard to understand the way the whole machinery works without documentation...

Thanks for your help !

I'm having trouble too. Willing to help update the docs once I get a better understanding of how the SymbolLayer works. I was using the PointAnnotation to render a custom view that was loading an external image from a uri. It's not clear how to do this via the SymbolLayer.

@jimjeffers Can you tell me how you changed from the PointAnnotation to the SymbolLayer? My app is working with annotations and i want to change since its deprecated. Having a hard time, since i have a lot of points on the map. Thanks

I'm a bit confused too ... would appreciate some explanation on how this new component works as compared to PinAnnotation

Do we have any update on that one ?
In the documentation It's write that iconSize is a number and in the example (ShapeSourceIcon) there is that case :

 iconSize: [
      'match',
      ['get', 'icon'],
      'example',
      1.2,
      'airport-15',
      1.2,
      /!* default *!/ 1,
    ]

Following the actual docution, I have difficulties to understand how this one should work...
