[maplab-users] Problems with raster image

[Germán CONAE]

I need your help.
  
I made a MAP file with multiple images RASTER (GEOTIFF) but when 
MapServer Shows them, they appear dark.
  
I copied a portion of the header and one layer to see as I'm generating 
the outputs.
  
This is an example:
  
OUTPUTFORMAT
     NAME jpeg
     DRIVER 'GD/jpeg'
     FORMATOPTION QUALITY=100
     MIMETYPE 'image/jpg'
     IMAGEMODE RGB
     EXTENSION 'jpg'
 END
  
LAYER
     NAME 'MyImage1'
     GROUP 'celdas3x3'
     PROCESSING "BANDS=3,2,1"
     OFFSITE 74 75 77
     DATA 'image_1.tif'
     STATUS ON
     TYPE RASTER
     METADATA
         WMS_SRS 'epsg:4326'
         WMS_TITLE 'Celdas-3x3'
         WMS_GROUP_TITLE 'celdas3x3'
         WMS_FEATURE_INFO_MIME_TYPE 'text/html'
     END #METADATA
  
     PROJECTION
         'init=epsg:4326'
     END #PROJECTION
 END #LAYER
  
This is a capture the gdalinfo -stats myImage.tif

 I tried to use the library GDAL / GTIFF, but didn't show nothing.
  
Any suggestions?
  
Thank you in advance
