[mapserver-users] Mapserver 7.0 and NODATA setting

So my question is a little different.

Seem that mapserver was not able to automatically understand the
NODATA values of floating point rasters.

In my usecase: the NODATA value is -9999.0
I produce the catalog using gdaltindex, and apply the result to mapserver 7.

The result is this:

The only partially solution I found was to set
OFFSITE 0 0 0
but it is acceptable for my usecase because the black color is a color
really available inside the rasters and it is not usable as a
transparent color.

Is this an issue for mapserver 7 ?

Thx,

A.
