Importing Binary Images [message #28873]

I'm new to idl, and am trying to import a binary grid that was created
on a windows machine into idl on a linux machine. It's least
significant byte first, 1561 rows, 2041 cols.

I searched the archives and found a thread that suggested used the
following syntax:

IDL> openr, 1, 'gom15dd.dat'
IDL> ms = bytarr(1561, 2041)
IDL> readu, 1, ms
IDL> tv, ms

While this 'works', the image displayed is incorrect - sort of looks
like speckled white noise. Any thoughts on what I may be doing wrong.
For a newbie, what's the difference between using readu, and
read_binary? The online help didn't help. Thanks.
