Hi, I am working through some issues with labeling my latitude lines on the extreme right side of a WMS pull. I have the labels generating where I want, but only for a couple of specific zoom levels. What I would like to do is determine how much space a given label would be in degrees (since I am using 4326 for everything) and subtract that from the edge of my wms_bbox. I got the log algorithm from: http://gis.stackexchange.com/questions/159197/can-textsymbolizer-font-size-be-set-as-a-function-of-the-scale
This is the SLD rule:
