I am trying to display lines with specific attributes contained in a field
The field (from Mapinfo) contains for example Pen(4, 2, 16711935)
I will need to convert the 3rd number to a hex colour and the first to the line thickness
So far I have
<LineSymbolizer>
<Stroke>
<CssParameter name="stroke">
#FF0000
</CssParameter>
<CssParameter name="stroke-width">
<ogc:Function name="strSubstring">
<ogc:PropertyName>MI_STYLE</ogc:PropertyName>
<ogc:Literal>5</ogc:Literal>
<ogc:Function name="strIndexOf">
<ogc:PropertyName>MI_STYLE</ogc:PropertyName>
<ogc:Literal>,</ogc:Literal>
</ogc:Function>
</ogc:Function>
</CssParameter>
</Stroke>
</LineSymbolizer>
The difficulty is working out how to convert the number 1671168 to the hex colour, in this case #FF0000. Has anyone done this before?

Has anyone done this before? I can't think of a good way to do that with the current toolset. I guess one would need some new filter functions that can do the parsing you need, that at the moment requires some java programming (we have been talking about having some scripting ability for a while, but so far nothing is evolved enough to ship with GeoServer, even if just as an extension) Cheers Andrea -- ------------------------------------------------------- Ing.

The MapInfo color coding scheme is documented here: http://georezo.net/jparis/MI_Enviro/Colors/color_models.htm#6-1%20R,G,B%20%3C%3E%20RGB RGB = (65536 * R) + (256 * G) + B With this formula, you should be able to get the R, G and B and transform them to hex. 2011/10/30 Andrea Aime <andrea.aime@...>: > On Fri, Oct 28, 2011 at 2:12 PM, Andy Berry <Andy.Berry@...> wrote: >> I am trying to display lines with specific attributes contained in a field >> >> The field (from Mapinfo) contains for example Pen(4, 2, 16711935) >> >> I will need to convert the 3rd number to a hex colour and the first to the >> line thickness >> >> So far I have >> >> <LineSymbolizer> >> >> <Stroke> >> >> <CssParameter name="stroke"> >> >> #FF0000 >> >> </CssParameter> >> >> <CssParameter name="stroke-width"> >> >> <ogc:Function name="strSubstring"> >> >> >> <ogc:PropertyName>MI_STYLE</ogc:PropertyName> >> >> >> <ogc:Literal>5</ogc:Literal> >> >> >> <ogc:Function name="strIndexOf"> >> >> >> <ogc:PropertyName>MI_STYLE</ogc:PropertyName> >> >> >> <ogc:Literal>,</ogc:Literal> >> >> >> </ogc:Function> >> >> </ogc:Function> >> >> </CssParameter> >> >> </Stroke> >> >> </LineSymbolizer> >> >> The difficulty is working out how to convert the number 1671168 to the hex >> colour, in this case #FF0000.

Solution was to remove the # from the colour and present as the original decimal provided by mapinfo easyloader. I have listed the whole style for any one who wants it.
