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.a...@geo-solutions.it>: > On Fri, Oct 28, 2011 at 2:12 PM, Andy Berry <andy.be...@wrexham.gov.uk> 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.
