Hi, I'm experimenting with the ground unit uom SLD extension in geoserver as described here: http://docs.geoserver.org/latest/en/user/styling/sld-extensions/uom.html using the geoserver 2.2-RC1 binaries.
while it seems that the ground unit uom extension works fine for simple strokes, it doesn't seem to work with non-trivial strokes. for example, when trying to use this feature with a dasharray, say: <sld:PolygonSymbolizer uom="http://www.opengeospatial.org/se/units/metre";> <sld:Stroke> <sld:CssParameter name="stroke">#000000</sld:CssParameter> <sld:CssParameter name="stroke-width">50</sld:CssParameter> <sld:CssParameter name="stroke-dasharray">6 3 6 3 24 3</sld:CssParameter> </sld:Stroke> </sld:PolygonSymbolizer> no dashes are displayed, the rendered stroke is a continous stroke. or, when trying to use this with a graphic mark, for example trying to create 1m wide strokes at right angles with the original line (to depict a railway): <sld:LineSymbolizer uom="http://www.opengeospatial.org/se/units/metre";> <sld:Stroke> <sld:CssParameter name="stroke">#000000</sld:CssParameter> <sld:CssParameter name="stroke-width">8</sld:CssParameter> </sld:Stroke> </sld:LineSymbolizer> <sld:LineSymbolizer uom="http://www.opengeospatial.org/se/units/metre";> <sld:Stroke> <sld:GraphicStroke> <sld:Graphic> <sld:Mark> <sld:WellKnownName>shape://vertline</sld:WellKnownName> <sld:Stroke> <sld:CssParameter name="stroke">#000000</sld:CssParameter> <sld:CssParameter name="stroke-width">1</sld:CssParameter> </sld:Stroke> </sld:Mark> <sld:Size>12</sld:Size> </sld:Graphic> </sld:GraphicStroke> <sld:CssParameter name="stroke-dasharray">12 18</sld:CssParameter> </sld:Stroke> </sld:LineSymbolizer> here, geoserver actually hangs (it uses a lot of CPU power, but no images are returned in the openlayers preview window) might it be the case that this extension is limitied to trivial strokes? if I wanted to make this work for the above cases as well, where would I look in the code for it?
