If you have moved to 6.2, you can consider using ANCHORPOINT http://mapserver.org/trunk/en/mapfile/symbol.html
On earlier verions you could try the approach suggested in http://mapserver.org/trunk/en/mapfile/symbology/construction.html#tricks But that is kind of similar to what you have tried yourself. To avoid gaps you could try this: SYMBOL NAME 'SQUARE_FULL' TYPE vector FILLED true POINTS 0 0 0 1 1 1 1 0 0 0 END END SYMBOL NAME 'SQUARE_R' TYPE vector FILLED true POINTS 0.5 0 1 0 1 1 0.5 1 0.5 0 END END CLASS STYLE SYMBOL "SQUARE_FULL" COLOR [LEFT_CLR] SIZE 10 END STYLE SYMBOL "SQUARE_R" COLOR [RIGHT_CLR] SIZE 10 END END It seemed to work for me on 6.0.

Hi, I'm trying to draw a point layer, with each point represented in two colours (for example a square split in two with one half red and one half green). I can create the symbols and apply the data but either the squares are the incorrect shape, or they overlap. The closest I got was with the following CLASS definition, but then it appeared the colours were shown on the wrong side of the square. Images and further details at http://gis.stackexchange.com/questions/35283/mapserver-symbol-with-two-colours Symbol definitions: |SYMBOL NAME 'SQUARE_L' TYPE vector FILLED true POINTS 0 0 0 1 0.5 1 0.5 0 0 0 END END SYMBOL NAME 'SQUARE_R' TYPE vector FILLED true POINTS 0.5 0 1 0 1 1 0.5 1 0.5 0 END END # CLASS definition I'd like to symbolise a point dataset with a square (or circle) using two colours. This is useful for displaying values collected on both sides of a road (for example). split symbols I created two symbols, a left side and right side of the square as shown below: SYMBOL NAME 'SQUARE_L' TYPE vector FILLED true POINTS 0 0 0 1 0.5 1 0.5 0 0 0 END END SYMBOL NAME 'SQUARE_R' TYPE vector FILLED true POINTS 0.5 0 1 0 1 1 0.5 1 0.5 0 END END Then in my LAYER I can create a CLASS using the two different STYLES: CLASS STYLE SYMBOL"SQUARE_L" COLOR [LEFT_CLR] SIZE 10 END STYLE SYMBOL"SQUARE_R" COLOR [RIGHT_CLR] SIZE 10 END END | Any help appreciated, Seth _______________________________________________ mapserver-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapserver-users
