Fu Chen,

While I believe there is going to be a dialog developed for OpenEV which
allows a user to describe the format of a raw file, I was not aware of any
dependable way to "guess" the layout of raw files.  If it is easily done it
would be good to incorporate into that tool.

I wouldn't want to have GDALOpen() try to guess raw file layout on it's own
though.  To dangerous.

Best regards,
