[Mapserver-users] Max number of layers craps out at about 295

[Stephen Clark]

Frank and others,

I see in the 4.0.1 release that maxcolors is set to 256 and maxclasses is
set to 250.

#define MS_MAXCOLORS 256
#define MS_MAXCLASSES 250


So can I make the assumption that to increase the number of layers I DO NOT
NEED to touch these
#define's?

thanks,
Stephen
