I'm trying to switch from raster map to vector map in OpenLayers using mapbox-gl library, but for some reason map export to png is not working properly: map rendered with mapbox-gl is not visible on exported image. I see only other (geojson) layers, but not map. With raster maps it works properly. I'm using export as in example here: https://openlayers.org/en/latest/examples/export-map.html
If you are using a Mapbox-gl layer in OpenLayers as in https://openlayers.org/en/latest/examples/mapbox-layer.html you will need to add
preserveDrawingBuffer: true,
to the mapboxgl.Map
options to make it exportable.
Then to include it in the OpenLayers export you will need to add canvas.mapboxgl-canvas
to the querySelectorAll
list.
