The implementation of GAP has been fixed (center to center distance between symbols), and so has the calculation of symbol height. I guess that the following should work:
STYLE SYMBOL "wavy_line" WIDTH 1 SIZE 2 GAP -6 COLOR 0 0 0 END Since you have y values from -1 to 1, and x values between 0 and 6, the ratio between the height of your symbol and the length is 2 / 6. The ratio between size and gap should be the same to make the the line continuous. Håvard On 8/29/2013 1:31 AM, TC Haddad wrote:
Hello, I'm trying to understand symbol orientation and (maybe) use of ANCHORPOINT on a line in Mapserver 6.2. The vector symbol that I have been using for line cartography in MapServer 6.0.3 is below, and I am trying to get the same effect in Mapserver 6.2.1. SYMBOL NAME "wavy_line" TYPE vector POINTS 0 0 1 1 2 1 3 0 4 -1 5 -1 6 0 END END Display in Mapserver 6.0.3: https://dl.dropboxusercontent.com/u/42845001/mapserver6.0.3.png Relevant Style bloc from Mapserver 6.0.3: STYLE SYMBOL "wavy_line" WIDTH 1 SIZE 2 GAP -1 COLOR 0 0 0 END This did not translate directly to Mapserver 6.2.1, but I came close with this: STYLE SYMBOL "wavy_line" WIDTH 1 SIZE 4 GAP 6 COLOR 0 0 0 END which produced this: https://dl.dropboxusercontent.com/u/42845001/mapserver6.2.1.png Obviously I am missing something about how to get the symbol to orient along the line, I played with ANCHORPOINT as that was new in 6.2 and it seemed like the default of 0.5 0.5 should work for my symbol, but I also tried several other value combinations and it seemed to merely shift the symbol around laterally, while maintaining an upright orientation. So I'm a bit confused on how to achieve the original effect, (behavior something like the equivalent of FOLLOW for Labels). Any pointers appreciated... _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
