Sergio,
There are a few variations on the kinds of BMP files produced depending
on the input file. From a quick scan of the code, it looks like 1 band
input files result in a pseudocolored BMP file (greyscale if there is no
provided colormap), and 3 bands files are treated as RGB.
There may be a few other variations I am not aware of. You might want
to skim the user driver documentation.

Mainly, because no one has contributed one, or paid for the implementation
of one. I would like to see direct Idrisi support.
Best regards,
