Re: [Geoserver-users] SLD filter function usage
Hi, I meant since I could not find the solution I did a workaround by changing the geometry and using a different function(startPoint()). I tried just now your solution, but it returned with : ServiceExceptionReport version=1.1.1 ServiceException java.lang.RuntimeException: Unable to find function numPoints Unable to find function numPoints /ServiceException /ServiceExceptionReport It gave the same for round(), so I removed it from SLD. Will search for the error, but am busy with other things in the project. Thanks again for your time.

Re: [Geoserver-users] SLD filter function usage
Hi, I changed the geometry, so that I can use the startPoint() function :). Anyways thanks for the info. I was curious how this thing could be achieved in SLD structure. Afterall its an XML structure with name value pairs, so understanding passing a value to a filter function, like in this case startPoint() where the_geom is passed and it applied some style at the start point of geometry, is easy. But couldn't understand how do we read the return value from a function like numPoint() and do some thing with it. Anyways thanks again. Appreciate your help.

Re: [Geoserver-users] SLD filter function usage
Hi, Thanks for the reply. I wan't to place a symbol on the boundary of the ellipse at the top. In my question I had pointed two filter functions (numPoints and pointN) which I guess could be useful but I don't know how to use them. I could find any documentation on their usage. If someone has idea about how in SLD we use a filter function (numPoints) which returns a value(n) and then performing an arithmetic operation on that return value (3/4*n), please suggest. thanks -- View this message in context: http://osgeo-org.1560.x6.nabble.com/SLD-filter-function-usage-tp5146766p5147010.html Sent from the GeoServer - User mailing list archive at Nabble.com. -- Open source business process management suite built on Java and Eclipse Turn processes into business applications with Bonita BPM Community Edition Quickly connect people, data, and systems into organized workflows Winner of BOSSIE, CODIE, OW2 and Gartner awards http://p.sf.net/sfu/Bonitasoft ___ Geoserver-users mailing list Geoserver-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/geoserver-users
[Geoserver-users] SLD filter function usage
Hi, I am applying a symbol to a point on ellipse. For this i used the startPoint function, but my ellipse's coordinates start from the right side on the curve so it wrongly places the symbol at the right side. I found numPoints and pointN functions which I thought of using for this by getting no. of points on ellipse from numPoints and using pointN to place the symbol at 3/4* numPoints. This is just logic which I am not sure if could be applied. Please help if someone knows how to write this in SLD , please suggest or some other way of achieving this through other functions.
