In DataMiner Maps we’d like to have markers to be rotated by an angle specified in element parameter, specifically an arrow marker showing the heading of a vessel.

A) Can DataMiner generate the rotated images or B) do they have to be fetched from a different source using URL arguments including the rotation angle?

According to the help on MarkerDetails, the placeholders for a MarkerImage in MarkerDetails can be generated same way as for PopupSkeleton in PopupDetails. However, the placeholders in the url attribute of MarkerImage are not filled in, while the placeholders in PopupSkeleton are filled in correctly using the same Detail tags. The Layer is using sourceType=”objects”. See below screenshots and xml configuration. We’re using DM v10.2.0-CU11.

If this is possible, could you please review the config and provide a working example of a marker rotated by an angle specified in element parameter?

Thanks a lot.
