Reg : Individual Layer transparency within ArcGISDynamicMapService

VikramS — Fri, 28 Feb 2014 02:06:27 GMT

Hi all

Documentation shows that individual layer transparency can be achieved using LayerDrawingOptions . But when I setlayerdrawingoptions the layer transparency doesn't work . Does the image format of the map service needs to be different . Currently it is PNG8 . Please advise .

Thanks

Hi Vikram,

Try to refer to the below sample for better understanding:
https://developers.arcgis.com/javascript/jssamples/renderer_dynamic_layer_change_attribute.html

Alternatively you can create a jsfiddle and share your code so its easier to understand the issue better and provide help faster.

Hope this helps.

Best Regards,
Manish

Hello Manish,

Thanks for the reply . Actually I saw that example but the difference is I am trying to use a slider to let user change the transparency of the layer . In the example layerdrawingoptions are set before adding the layer to the map .
