Class definition looks like this:
LAYER
NAME total_co2_90.tif
TYPE RASTER
STATUS DEFAULT
DATA total_co2_90.tif
PROJECTION
'init=epsg:4326'
END
END
Normally, when dealing with shapefiles, I have something like this:
CLASS
NAME 'Units: Teragrams CO2 Equivalent'
EXPRESSION ([value]=-110003)
TEMPLATE 'units as title in legend'
END # CLASS
CLASS NAME '0 to 111'
EXPRESSION ([value]<=111)
COLOR 255 255 178
.....
As I have many different raster files, it would be somewhat of a
hassle to hard-code their legends (in mapfile form). These legends are
loaded separately as GIFs.
I just want to have an additional info displayed, the units, which I
would like to display dynamically, as they can be expressed in
different languages.

What do your faked classes look like?

That's for the statistical data. The TIF data would display a pre-
prepared GIF legend, plus the UNITS info.
I would like to add information about the Units of the selected
variable into the legend. When using vector data, this wasn't
really
the problem. I kind of faked empty classes to insert that
information.
But now, I wonder how to achieve this when using TIF images. As the
TIF is already color coded and regrouped into a couple of classes,
using faked CLASS values, results in the display of zero pixels -
nothing is being displayed.
Is there another way to "slip" in some information into the legend?
Or
is the HTML legend the only alternative?
