[mapserver-users] Mapserver 7.0 and NODATA setting

[Andrea Peri]

Hi Jukka.

Perhaps you have right !

The NODATA setting is an ancient setting that I reuse always in my
mapfiles but only now I notice that the mapserver document don't
report him.
So more probably it is a false setting.

But , if the nodata setting dont exist, how say to the mapserver to
filter the nodata of a floating raster  ?

Thx.
