[mapserver-users] GEOMTRANSFORM LABELPNT example

[Lime, Steve D (DNR)]

The intention was for the grey circle to be drawn at the computed label point. The most common use case is drawing a marker with associated text and you don't want them to overlap. If you do want them to overlap, use case would be labeling a highway shield then you must use POSITION CC.

Here is an image and the map file we are using ms4w  3.0.3.



We thought the larger grey circle should be drawn in the center of the label text.



What have we done wrong?



Thanks



Ian

Brent,



We copied the example

http://osgeo-org.1803224.n2.nabble.com/GEOMTRANSFORM-labelpnt-location-t

d6408065.html.



However we see the GEOMTRANSFORM labelpnt drawing the circle on the point location not the center of the label text.



Thanks



Ian

Ian,



  How are you specifying it in your mapfile?
