[Mapserver-users] Hidden Layer

[Guillaume MOCCAND]

Hi List !

i wonder how MS draws the map Layers.
if i have an Image Layer completly hidden by a vector layer, will MS spend time 
reading the Tiff File ? or will it ignore it ?

my layer-renderers are scale-dependent but because the layer image is hidden by 
the other layer at a given scale, i don't know if it is better to set its 
status to "OFF"

regards
