compressionQuality

The compression quality. Compression quality is a value from 0 to 100 or NaN. A lower number reduces the size of the exported tile package, but reduces the quality. This applies to JPEG format tiles. If the value is NaN the service will use its default compression quality. The default compression value for the service is accessible on the services metadata under com.arcgismaps.mapping.layers.TileInfo.compressionQuality.
