Marcin,

In fact there is no way to let MapServer do "regular" rendering of a raster
layer if there are any classes.  If there are classes, they are used to color
the raster.

As I understand it, you were creating a class on the layer in an effort to
introduce a legend entry, is that right?  Lots of folks run into the same
issue and I think we need a different way of introducing legend entries.

I have add mapserver-users back into the address since some of this information
could be of use to others.

Best regards,
