[mapserver-dev] label MINSCALEDENOM, MAXSCALEDENOM usage

[李杨]

    Hi. I use basemaps to generated the .mapfile for my osm postgis data.
But I found some lable in the mapfile such as"MINSCALEDENOM,MAXSCALEDENOM".
I am not very understand these labels. If use these labels,when enlarge
,will make the image disappear. If I delete the labels in th emapfile,
enlage will no problem. I mean enlarge is I using a link like this:"
http://127.0.0.1/cgi-bin/mapserv?&map=/home/jack/osm-demo/basemaps/osm-google.map&layer=all&template=openlayers",
then click the enlarge. Can anyone give some guide?

Also I use the mafile which basemaps generated automaticlly, using the
above do not show any content, but if  I move the
MINSCALEDENOM,MAXSCALEDENOM" label , it will show some content.
