[mapserver-users] vector Symbol and anchorpoint
Hi, I'm having trouble try.ing use the anchorpoint with a vector symbol. Is this working with vectors ? This is what I'm try to do: SYMBOL NAME test TYPE vector FILLED TRUE POINTS 0.5 1.0 0.5 0.75 0.0 0.75 1.0 0.75 END ANCHORPOINT 0.0 0.0 END The anchorpoint seem always set to the 0.5 0.5 position. I'm use the trunk version of mapserver. -- - Andrea Peri . . . . . . . . . qwerty àèìòù - ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

try defining the points of your vector symbol such that min(x)=min(y)=0 On 11 August 2013 10:30, Andrea Peri aperi2...@gmail.com wrote: Hi, I'm having trouble try.ing use the anchorpoint with a vector symbol.

Re: [mapserver-users] vector Symbol and anchorpoint
As you're not showing what you would like to obtain, nor the mapfile you are using to generate those images it is difficult to be of much help. I have added a test in https://github.com/mapserver/msautotest/commit/89d59a49586dc3192dfd2f67bd1a751f0900e36f that mimics what I guess you would like to obtain, and for me shows that anchorpoint seems to be working as expected. -- thomas On 11 August 2013 13:07, Andrea Peri aperi2...@gmail.com wrote: Hi, thx for response.

I show this in the img2 attacched. So mapserver seem move the symbol when there is a perpendicular segment. Is this a bug or I don't understand how work the symbols ?

Re: [mapserver-users] vector Symbol and anchorpoint
Hi, Sorry, I forgot to explain my need. I need to define an outline of polygon with an perpendicular segment forward the internal of polygon. It goal is to allow to use only the outline (no internal fill) and also help the user to distinguish the internal and the external part of a polygon when the scale is bigger and the polygon is not all in the screen. The problem is that the symbol don't start exactly from the outpline but a little before.as it was moved.

Re: [mapserver-users] vector Symbol and anchorpoint
Andrea, the example I gave you does exactly that. https://github.com/mapserver/msautotest/blob/master/renderers/line_anchorpoint.map#L20 , just remove the first style's COLOR if you don't want a fill. -- thomas On 11 August 2013 14:37, Andrea Peri aperi2...@gmail.com wrote: Hi, Sorry, I forgot to explain my need.

Re: [mapserver-users] vector Symbol and anchorpoint
Hi Thomas. It work very well. I tried to define a symbol with two segment: one perpendicolar to the other. Instead more simple was to create an only one segment perpendicular to the outline.
