10019: Layer uses symbol level drawing with a non-simple fill symbol
You have a map layer that uses a nonsimple fill symbol for symbol level drawing display, which can potentially impact the performance of dynamic map rendering.
- Check the drawing performance of your basemap layer in ArcMap or your map service in the Preview window. See Working with basemap layers or Publishing map services for more information.
- If you need to make changes, right-click this warning message in the map analysis results panel and click Change symbol to edit the symbol. Then, change the symbol to a type other than a picture fill symbol, such as a simple fill symbol.
Basemap layers and optimized map services use a new graphics pipeline that can employ a high-performance processing method to draw symbol levels. However, certain symbols, such as picture lines, picture markers, and character markers, are incompatible with this high-performance method. You can choose to mark this warning as an exception to avoid receiving the warning next time you analyze the map. This layer will then use a slower method to perform symbol level drawing for this layer.
