Dear Max,

I have done this way

envi_open_file, file1, r_fid=_rfid1
envi_file_query, _rfid1, ns=_ns1, nl=_nl1, nb=_nb1, dims=_dims1,
data_type=_datatype1, interleave=_interleave1, xstart=_xstart1,
ystart=_ystart1
_mapinfo1 = envi_get_map_info(fid=_rfid1)

envi_open_file, file2, r_fid=_rfid2
envi_file_query, _rfid2, ns=_ns2, nl=_nl2, dims=_dims2
_mapinfo2 = envi_get_map_info(fid=_rfid2)

_xfactor = _mapinfo2.ps[0] / _mapinfo1.ps[0]
_yfactor = _mapinfo2.ps[1] / _mapinfo1.ps[1]

envi_doit, 'resize_doit', fid=_rfid1, pos=pos1, dims=_dims1, interp=0,
rfact=[_xfactor,_yfactor], r_fid=_rfid2a, out_name=tempfile

But the resampled file does not give the same number of pixels and
lines corresponding to high resolution image(file2). Kindly suggest me
to fix this problem.

Thanks for your help.
