Pink Tiles

The dreaded pink tile problem (or lack of tiles in FF) means that something has gone awry in your setup. Try viewing the request for one of the tiles in Firebug - you'll probably find either an error message has been returned or that the tile just cannot be found.

Black Tiles

In order to prevent maps turning black when layers are turned on, please note the following:

  • The following parameters should be used in the .map file:
   IMAGETYPE AGG_PNG
   OUTPUTFORMAT
      NAME        "AGG_PNG"
      DRIVER      "AGG/PNG"
      MIMETYPE    "image/png"
      IMAGEMODE   "rgba"
      EXTENSION   "png"
      TRANSPARENT TRUE
   END
  • The following entries need to be configured in the Studio Settings for iShare
    • General Settings > WebService > ImageFormat = PNG
    • General Settings > Web > MapType = OpenLayers
