[Mapserver-users] PNG Annotation Symbol Color Issue

[Daniel Morissette]

We have noticed a similar color problem in 4.0 with PNG symbols.  I 
copied your problem description to the bug:
http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=397

I noticed that a few others have reported colors problems that may or 
may not be related.  First suggestion to everyone: make sure you don't 
have multiple copies of GD or libpng on your system.  Once you have 
verified that, if you have a simple test case (mapfile and data) to 
reproduce the problem then please file a bug in bugzilla and attach the 
testcase and steps to reproduce to the bug help us figure the problems.

Thanks

Daniel
