Unable to have an image service zoom automatically to the extent of the service when it is added to a new web map in Portal for ArcGIS after version 10.4.1.
This issue is not reproducible in ArcGIS Enterprise 10.8.1, the current minimum supported version of ArcGIS Enterprise. Layers zoom automatically to the extent of image service when added to the map.
解决办法
Get the image service extent from the REST endpoint.
Use the Set Extent workflow and set the extent manually.
