[Mapserver-users] Re: More info on strange mapserv - mode=map behavior

[Sean Gillies]

Mike,

There have been some other reports of problems with the GD library
that people are getting from the ms4w package.  At the mapserver
users meeting I experienced problems with it.  There is at least
one other bug in bugzilla reporting problems with drawing JPEG
imagery larger than a certain dimension.

   http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=746

MapServer is not to blame here, IMO.  I think that a buggy imaging
library is being distributed.

Could you provide more info about the source of your 4.2 binary?
Then we can get the distributors to take a look at it.

cheers,
Sean
