Description
The cause of those "value cannot be less than zero" exceptions in MgRenderingService::RenderDynamicOverlay is most likely caused by the AJAX Viewer firing off GETDYNAMICOVERLAYIMAGE requests willy-nilly without any sort of client-side verification.
The viewer should be doing this verification. Do not send a GETDYNAMICOVERLAYIMAGE request if any of the parameters are <= 0:
- width
- height
- dpi
- scale
- metersPerUnit
This should cut down on the incidences of such exceptions being logged server-side
