Hi, I'm trying to figure out how to get a smooth transparency ramp with a raster heatmap.
I've been messing around with value ranges in the Transparent Pixel List and tried using the value picker but the results are not what I'm after — the heatmap still has a hard edge rather than a nice ramp from 0 to 100% transparency from max to min value. I suspect that the answer (if there is one) lies in setting the Transparency Band to use the values of the heatmap (Band 1 Gray, min 0, max 0.0195356) but it doesn't do anything. Can someone who understands how this tab is supposed to work explain if I can achieve what I want? I'm not too fussed if the transparency ramp isn't interpolated like the singleband pseudocolor styling, though that would be nice :) Cheers, Nathanael Boehm UX designer specialising in business web & mobile apps www.purecaffeine.com <http://www.purecaffeine.com/professional/> Canberra, Australia 0431 698 580
