Are points as circles supported?

[electricsam]

I'm currently using a MVT layer based on TerriaJs' implementation. I've customized it to support drawing points as circles. However, I would like to use your library as it is more complete than what I am using.

I'm running into an issue though. It seems that with your library, entire tiles are colored, rather than having circles drawn. Polygons seem to work just fine.

Here is my config:

    const exampleConfig = {
      showCanvas: true,
      style: {
        version: 8,
        sources: {
          layer1: {
            type: 'vector',
            tiles: [`${BASE_PATH}${BASE_API}/mvt/{z}/{x}/{y}.pbf`],
            // tiles: ['https://api.mapbox.com/v4/mapbox.82pkq93d/{z}/{x}/{y}.vector.pbf?sku=1012RMlsjWj1O&access_token=pk.eyJ1IjoiZXhhbXBsZXMiLCJhIjoiY2p0MG01MXRqMW45cjQzb2R6b2ptc3J4MSJ9.zA2W0IkI0c6KaAhJfk9bWg'],
          },
        },
        layers: [
          {
            id: 'background',
            type: 'background',
            paint: {
              'background-color': 'transparent',
            },
          },
          {
            id: 'point',
            source: 'layer1',
            'source-layer': 'casts',
            type: 'circle',
            paint: {
              'circle-color': '#11b4da',
              'circle-radius': 4,
              'circle-stroke-width': 1,
              'circle-stroke-color': '#fff',
            },
          },
        ],
      },
    };

And I am using it:

const p = new MVTImageryProvider(exampleConfig);
layers.addImageryProvider(p);

Attached is a screen shot with both my MVT layer and yours. My library is drawing yellow circles, while yours is coloring some tiles entirely teal, rather than drawing teal circles.
