◆ fromEsriJson()
| bool QgsVectorTileMatrixSet::fromEsriJson | ( | const QVariantMap & | json, |
| const QVariantMap & | rootTileMap = QVariantMap() |
||
| ) |
Initializes the tile structure settings from an ESRI REST VectorTileService json map.
- Note
- This same structure is utilized in ESRI vtpk archives in the root.json file.
Optionally, a rootTileMap can be specified for indexed vector tile datasets (since QGIS 3.32)

Returns a vector tile structure corresponding to the standard web mercator/GoogleCRS84Quad setup.
