If you just want to make the black disappear you could use
MAP
IMAGECOLOR 255 255 255 # set map's background color to white
LAYER
TYPE RASTER
OFFSITE 0 0 0 # make this color (black) of the input raster file
transparent

Hello Everyone,
First time Mapserver user here, and I would appreciate some advice
regarding this problem:
I have a Tile Index of single band TIFF rasters (0-255). The rasters
are displayer fast, and accuratly. However these rasters cover a sea
shore area, this means that half the rasters are sea territory, wich
is represented in black (0 cell values)
Is there way, in the Mapfile to reclassify the 0 cells to 255 in order
to turn them white? I know I can always pre process the rasters, but
I'm talking about forty + files...
Thanks in advance,
Cheers,
André Mano
