2 Color (1 bit) tiff files

[Stephen Lime]

In 3.3 I implemented raster classes which allows you to recolor images on-the-fly.
Here's an example assuming that 0 is offsite and 1 is data in your tiff images:

LAYER
  NAME rivers
  DATA rivers.tif
  TYPE RASTER
  CLASS
    EXPRESSION "1"
    COLOR 0 0 255
  END
  OFFSITE 0
END
LAYER
  NAME roads
  DATA roads.tif
  TYPE RASTER
  CLASS
    EXPRESSION "1"
    COLOR 255 0 0
  END
  OFFSITE 0
END


I haven't tested this with bit images so let me know if you run into any problems.

I have several huge (20 000 x 20 000 pixels) 2 color tiff files that
represent different layers (rivers, roads).
How can I make MapServer to draw these files in different colors?
