Andrea,
You can try one other aproach.
Create your image in ps using gmt (grdimage, grdview). Don't use the -B
option (which plot the frame and anotations). Use ps2raster
(new in 4.1 version) to do the conversion ps->tiff. Write a .tfw file
using the output of grdinfo on the grid used to produce the ps image.
You can now use gdal_translate to convert the tiffedPS.tiff + .tfw into
a geotiff image.
