Hi,
You should try to give more exact description about your problem. By reading
several mails which you have sent to MS4W list I believe that you are still
talking about the same images. That is 3-band, 8 bits per band images stored
into database as PostGIS raster and which you have tried to classify into
classes with something like this
CLASS # beginning of the class parameter
NAME "Very Low"
EXPRESSION ([pixel] > 0 AND [pixel] < 47)
STYLE
COLOR 243 231 172
END # end style for class
END # end class for class very Low
I had a try with some png file I found from my machine by using this in the
mapfile
LAYER
NAME "classified"
DATA "C:\ms4w\apps\data\8000000.png"
debug 10
TYPE RASTER
STATUS ON
PROJECTION
"init=epsg:3067"
END
CLASS
NAME "test"
EXPRESSION ([pixel] > 100 AND [pixel] < 250)
# EXPRESSION ([red] > 100 AND [green] > 100 AND [blue] > 100)
STYLE
COLOR 0 255 0
END
END
END
Both expressions work so Mapserver does support classification of 3-band, 8
bits per band png images.
Try you to convert your raster from the database into image file and repeat
your test. It if works from a file but not from PostGIS raster then you know
that the issue is somewhere in PostGIS raster handling.
