Fwd: [mapserver-users] Failed to show Arabic labels with MapServer 5.2

[Stephen Woodbridge]

OK, this is great. I think I learned something new then.
With ANGLE AUTO you can ask GD to draw the whole string at the specified 
angle. But there is not equivalent function in GD for ANGLE FOLLOW. The 
only way we can do that is one character at a time, changing the 
insertion point and angle of each character.

I know Thomas has put a lot of effort into make the AGG render well 
integrated with mapserver. It would probably be a good idea to document 
this issue and the fact that the outlinecolor is what is causing in a 
bug. http://trac.osgeo.org/mapserver/  If you do not have an OSGeo 
userid, follow the link to get one first.

Thank you for your patience and Thank you, Tanya, for your excellent 
observations on this issue.
