View the layers for two ImageMapServices simultaneously

Last Published: April 25, 2020


I have two Image MapServices and I would like to view the two layers simultaneously.


  • If you are viewing the Image MapServices in ArcExplorer 3.1—Java edition or a Java Viewer, you can set the transparency of an Image MapService.

    To do this, make the MapService active, click the Layer Properties dialog, click the General tab, and use the Transparency slider to set the transparency value.
  • Transparency can also be set on an image. See the IMAGEPROPERTIES element in the ArcXML Programmer's Reference Guide for more information.
  • You can also set transparency for a particular color. To do this, add a background color in the PROPERTY tag in the map configuration file or in your GET_IMAGE request:
    <BACKGROUND color="255,255,255" transcolor="255,255,255" />

    The color white is represented as "255,255,255".

    See the BACKGROUND element in the ArcXML Programmer's Reference Guide for more information on which images support transparent colors.
