Custom tileprovider with tileSize=512 not showing up as higher resolution

[raynerhoward]

I have added a custom tileprovider (JPEG) to ConfigProvider.js which has a tileSize of 512x512. Following the examples provided for WMTS in your themesConfig.json,

        "tileSize": [
          512,
          512
        ],

I have added tileSize to my themesConfig.json for a TMS (XYZ) tile set:

      {
        "type": "tileprovider",
        "provider": "Ortho2020JPG",
        "name": "ortho2020jpg",
        "title": "2020 Ortho JPG",
        "thumbnail": "img/mapthumbs/default.jpg",
        "tileSize":[
            512,
            512
        ]
      },

But qwc2 doesn't show the 'extra' resolution at the same zoom level as compared to a similar tile set having the default tile size of 256x256. Using dev mode (yarn start, localhost:8081).

I've tried various ways of setting tileSize in ConfigProvider.js to no avail:

    Ortho2020JPG: {
        url: 'http://myurl.com/ortho2020jpg/{z}/{x}/{y}.jpg',
        tileSize: [512,512],
        options: {
            maxZoom: 16,
            tileSize: 512,
            attribution: ''
        },
        layerOptions: {
            tileSize: 512
        }
    },

I've also tried it with tilePixelRatio. Is it possible to specify a 512x512 tile size with TMS or XYZ tile sets?

QGIS handles the 512x512 tile size with tilePixelRatio=2 in the datasource URI. I'm able to see the 'higher' resolution (more detail) in QGIS as compared to a similar tile set that's using 256x256 tiles.

EDIT: Adding the data source URIs for the two tile services here:

tilePixelRatio=1&type=xyz&url=https://ewx-orthos.s3.us-east-2.amazonaws.com/ortho2020/%7Bz%7D/%7Bx%7D/%7B-y%7D.png&zmax=16&zmin=8

created using gdal2tiles from gdal 3.3.4

tilePixelRatio=2&type=xyz&url=https://ewx-orthos.s3.us-east-2.amazonaws.com/ortho2020jpg/%7Bz%7D/%7Bx%7D/%7By%7D.jpg&zmax=16&zmin=8

created using gdal2tilesp from https://github.com/roblabs/gdal2tilesp since it allows for parallel processing and JPEG tiles (to save space), unfortunately (for me) it created 512x512 tiles
