I have a problem with dynamic services. I am using ESRI Arcgis Server 10.3 and I have several layers as declared as 'ArcGISDynamicMapServiceLayer'.
When the layers show in the API it has a white small halo in all the labels and it makes it very difficult to read. It is a normal map service and is published without halos.
If I use the layers as 'FeatureLayer' the quality of the labels will be better and the halos won't show.
Also if I want to change with setHaloColor() .setHaloSize( ) in 'ArcGISDynamicMapServiceLayer' it wont work.
I am attaching an image with how it looks.
Thank you very much!
