PROCESSING "LUT=.... issue

[A.Th.C. Hulst]

Dear all,

I have been working on a method to display my freshly computed netCDF data 
through mapserver and are finally there. However, I find one last issue with 
the scaling / processing lut= combination.

Please see the map on http://mapserver.argoss.nl. The mapserver is svn 
revision 6353. There is a white spot on there that should be red. See the 
relevant map section below:

 LAYER
    NAME "Hs"
    DATA "netCDF:<SNIP>windwave/ww3_output.nc:sign_wave_height"
    PROCESSING "SCALE=0,10"
    PROCESSING "SCALE_BUCKETS=200"
    PROCESSING "BANDS=1,1,1"
    PROCESSING "LUT_1=96:0,157:255,221:255,255:240"
    PROCESSING "LUT_2=29:0,93:255,157:255,221:0,255:0"
    PROCESSING "LUT_3=28:255,93:255,157:0,255:0"
    TYPE RASTER
    STATUS ON
    OFFSITE 0 0 0
  END

The data in this layer is in [0 13.457]. I want to scale the image to [0 10] 
because more details of lower waves show. What happens is that the RGB values 
in the area that is clipped (eg Hs > 10m) are set to 255, regardless of 
anything in the PROCESSING instruction.

Am I overlooking something or should I report a bug (or feature ;) )?

Best regards,
Sander
