Transparent WebTiledLayer and PrintTask

GustafJonsson1

I am successfully using various online map tile services in my application (ArcGIS JS API) using the WebTiledLayer class. Some of them are in PNG format with and partly transparent.

It all works perfectly except when it comes to printing using the PrintTask class. It appears the PNG transparency is not honoured by the ExportWebMap geoprocessing tool?

I am using ArcGIS Server 10.2.1

Has anyone else had this issue? Is it a known issue or limitation? Any known workarounds?

I eventually figured out that this issue only occurs when the WebTiledLayer has opacity set to 1. As long as you avoid that by setting it to 0.99 or lower, the layers behaves as expected with the printTask andExportWebMap tool (PNG transparency alpha channel is honoured).

Hope this helps someone else.
