I am trying to change the opacity of the polygon fill when using the Region Resource from the HERE Map Image API.

Has anyone been able to get this right?

The resource documentation does not mention opacity anywhere. The only options available to alter the fill is fc,fc0,fc1,... which specifies the fill color itself.

And fc color parameter can be set with transparency. The first 2 digits in the hex value represents transparency and rest of 6 digits is rgb color:

fc1=80FF0000
