I published a service to ArcGIS Server 10.1 from an .mxd with no halos around the labels and created a flex application using the flex viewer. When I browse to the map here and zoom in on an individual trail segment, the labels become very grainy and appear to have a white halo around them, making them very difficult to read. It becomes exceptionally noticeable when imagery is used as a basemap.

Is there any thing I can do to stop the labels from getting all messy looking or is this just how they look when using flex?

  • Do you have anti-aliasing turned on for your features in your map service? – Radar May 15 '13 at 22:18
  • My Anti-Aliasing settings are as follows: Anti-Aliasing = none Text Anti-Aliasing=forced I tried changing these settings, clearing my browser cache, and revisiting the map but no luck on fixing it. – cl3 May 16 '13 at 13:43

Stick to standard web fonts. I've had luck with using Verdana black with white halos, if you want the halos. But it appears you do not.


I know this is an old question, but wanted to share that I fixed this problem by caching my services using PNG32 format instead of PNG8. I had tried changing my fonts prior to that and that didn't help.


Be sure to be using the standard label engine and not Maplex. Maplex doesn't work well with ArcGIS services.


I turned out to be a simple change of font that fixed my problem.
