    Did you remove the other PROCESSING
      directives?

        Hi Brent,

        Thanks for your reply. 

        I did that but don't work. When I remove PROCESSING
        "BANDS=1,2,3" MapServer assumes that is only one band so he
        retrieve the result of just one. 

        I have the class parameters like this:

        CLASS

          NAME "near white"

          EXPRESSION ([red] > 25 AND [green] > 25 AND [blue] >
        25)

          STYLE

            COLOR 0 0 255

        END # end parameter style

        END # end parameter class

        CLASS

         NAME "white1"

         EXPRESSION ([red] > 200 AND [green] > 200 AND [blue] >
        200)

         STYLE

           COLOR 0 255 0

        END # end parameter style

        END # end parameter class

        CLASS

         NAME "white2"

         EXPRESSION ([red] > 200 AND [green] > 200 AND [blue] >
        200)

         STYLE

           COLOR 255 0 0

        END # end parameter style

        END # end parameter class

        I already did that with 1 CLASS, 2 and finally 3. None of this
        works. 

        Any suggestion?

        Best Regards,

        José Santos

          Remove all your PROCESSING
            directives for the layer (see my previous email for
            details).

             Dear all,

              I try do change like Jeff propose but I can't succeed..I
              get always the following error: 

              <ServiceExceptionReport
              version="1.1.1"><ServiceException>

              msDrawMap(): Image handling error. Failed to draw layer
              named 'fapartest'.

              drawGDAL(): Unable to access file. Attempt to classify
              24bit image, this is unsupported.

              </ServiceException></ServiceExceptionReport>

              With this link:
              http://localhost/cgi-bin/mapserv?map=/var/www/africarastercrt.map&VERSION=1.1.1&Request=GetMap&LAYERS=fapartest&STYLES=&SRS=EPSG:4326&BBOX=-26.0057,-34.8229,60.0032,38.0053&WIDTH=700&HEIGHT=500&FORMAT=image/png;mode=24bit

              But I make some tests and I don't think that is
              OUTPUTFORMAT that have the error. I have on the LAYER
              section this parameter: PROCESSING "BANDS=1,2,3 

              because my image is a RGB image (0 - 255) but when I put
              only one band or two bands the result is the color from
              the first band (like explain on the raster data access)
              but only the color and not the layer. I have the outformat
              and the class parameter like this: 

              OUTPUTFORMAT # Parameter Output

               NAME png24

               DRIVER "AGG/PNG"

               MIMETYPE "image/png;mode=24bit"

               EXTENSION PNG

               IMAGEMODE RGB

              END # end of parameter Output

              CLASS

                NAME "near white"

                EXPRESSION ([red] > 200 AND [green] > 200 AND
              [blue] > 200)

                STYLE

                  COLOR 0 0 255

              END # end parameter style

              END # end parameter class

              I working with this since a long time and I don't
              understand why.. Also I have another raster image with
              just one band and works fine...any ideas/suggestions??

              Best Regards and thanks,

              José Santos
