[MS4W-Users] Image 24 Bit

[José Pedro Santos]

Hi Brent, 

Thanks for the reply. Im no using MS4W. In working on Linux and using the version 6.2.0

My mapfile layer is like this:

LAYER # beginning of the layer parameter
 NAME "fapartest"
 TYPE RASTER
 STATUS ON
 DATA "PG:host=localhost port=5432 dbname='Environment_Models' user='postgres' password='postgres' schema='public' table='africarastercerto' mode='2'"
 PROCESSING "NODATA=0"
 PROCESSING "SCALE=AUTO"
 PROCESSING "BANDS=1,2,3"
 PROCESSING "DITHER=YES"

CLASS # beginning of the class parameter
 NAME "Null"
 EXPRESSION "0"
 STYLE
 COLOR 255 255 255
END # end style for class Null
END # end class for class Null

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

CLASS # beginning of the class parameter
 NAME "Low"
 EXPRESSION ([pixel] > 47 AND [pixel] < 85)
 STYLE
  COLOR 132 205 51
END # end style for class
END # end class for class Low

CLASS # beginning of the class parameter
 NAME "Moderate"
 EXPRESSION ([pixel] > 85 AND [pixel] < 100)
 STYLE
  COLOR 95 202 31
END # end style for class
END # end class for class Moderate

CLASS # beginning of the class parameter
 NAME "High"
 EXPRESSION ([pixel] > 100 AND [pixel] < 125)
 STYLE
  COLOR 2 180 0
END # end style for class
END # end class for class high
CLASS # beginning of the class parameter
 NAME "Vey High"
 EXPRESSION ([pixel] > 125 AND [pixel] < 255)


I did the same to another raster file and works (only 1 band). This have 3 bands and when I change the parameter PROCESSING "BANDS=1,2,3" to  PROCESSING "BANDS=1,2" I have result but is a blank image. 

Best Regards,
José Santos

    Which version of Mapserver (or MS4W)
      are you using?

      

      I think this error has to do with processing the input imagery in
      your LAYER, not the generation of the output image.

      How are you trying to classify your input data?  What does your
      LAYER object definition look like in your map file?

      Best Regards,
Brent Fraser

          Hi Jeff, 

          

          Thanks again for your reply. I try to change but didn't work.
          Do you think that have something to do with the
          Format=image/png?? Just PNG don't reply 8 bits images?

          

          Also I have another raster image but that one works well. This
          have 3 bands and values between 0 and 255. I'm using MapServer
          version 6.2. 

          

          Another idea? 

          

          Best Regards,

          José Santos
