R: [Mapserver-users] Mapinfo symbols

[Ballini Yvain]

 Hi Daniel,

I'm turning to the topic of the orientation of point symbol, do you know where I can find on the mapserver source the part which manages the symbols tuned by OGR. I would like to try to do some update on my mapsrver version to solve this problem.
Thanks a lot.
Yvain.

Yvain,

Um, I checked the code and it seems that we ignore the angle value coming from STYLEITEM AUTO for point symbols. Could please you submit a bug with a small mapfile and arrow.tab to reproduce this? I'm not sure when we would have time to work on this, but with a testcase to reproduce it's always easier for us.

Thanks

Daniel
