Standalone WSI Service​

Deprecated. Use rationai-wsi-tile-source instead.

Do not load both modules. EmpaiaStandaloneV3TileSource.supports() matches the same /v3/{files,slides}/info URLs as RationaiStandaloneV3TileSource, and OpenSeadragon's autodetection takes the first match in namespace insertion order — so which class opens the slide depends on script load order. This class supports only the options the original EMPAIA service understands — format, quality and channels, applied as tile-request query parameters. plugin (slide-reader selection) is dropped, because the original service has no such parameter, and neither slide mappers nor authenticated access exist there: the slide id lives in the URL path and no option ever reaches /info.

A format: "tiff" request sets _dataFormat = "rawTiff", so tiles decode through the converter chain of whichever TIFF decoder module is loaded (webtiff, or the deprecated geotiff) and keep their native bit depth.

Migrate by switching the deployment to rationai-wsi-tile-source and naming it explicitly in the protocol entry:

"slide_protocols": {
  "rationai_wsi": {
    "url": "`http://localhost:8080/v3/slides/info?slide_id=${data}`",
    "tileSourceClass": "RationaiStandaloneV3TileSource"
  }
}

which bypasses autodetection entirely and makes the collision moot.
