Image Service Black Background Pixels

The Map Client may display image background pixels as black instead of transparent.

This is addressed by changing the Transmission Compression on the Layer Properties.

On the Image Service >Layer Properties>Display Tab, Select LZ77 from the Transmission Compression drop-down list.




INFORMATION: See this Blog Post for more details on how the transparency setting can be applied to Image Services in Dekho. Also check this Esri Help page for more information on Esri supported compression formats.
