[Gdal-dev] How to show ASTER hdf vnir's bands as a color image?

[wlx]

Hi all,
      I want to show my ASTER hdf vnir's bands as a color image,but
gdal_translate treat each band as a subdataset,and gdal_translate  deals
with one subdataset one time,so if I don't know how to merge the top three
bands as a rgb imae.
      
      Best regards,
