[mapserver-users] 5.6.1 version and labels

[Alan Boudreault]

Carlos, glad to hear that your issue is fixed.

This is a new feature of MapServer 5.6: the ability to automatically scale the 
symbology when resolution changes so that the map maintains the same look at 
each resolution. For more info: http://www.mapserver.org/development/rfc/ms-
rfc-55.html

What's happen with your mapfile is that you set the resolution to 99 (which 
means that you wanted an output map of reso 99), but you did not set the 
defresolution (which tells mapserver the initial resolution your mapfile is 
supposed to be). In this case, the behavior of mapserver is to scale all the 
values to preserve the look of the mapfile. Without this functionnality, to 
convert a mapfile that use initialy a resolution of 72 to a printable mapfile  
of resolution 300 (example), you would have to convert all the value/size of 
symbol line etc... manually.

regards,
Alan
