static void	setFormat (FABio::Format fmt)
	Set the FABio::Format in the program. This is the preferred way to set the output format in "new" FABs. When designing new programs, this should be the only function that needs to be called in order to set the format. More...

static void	setOrdering (FABio::Ordering ordering)
	Set the FABio::Ordering for reading old FABs. It does NOT set the ordering for output. This is deprecated. It exists only to facilitate reading old FABs. When you're reading in an "old" FAB, you must set the Ordering, before attempting to read it in. This is because FABs written out in the "old" format weren't self-describing; i.e. information such as the Ordering was lost when the "old" FAB was written out. More...

	Gets the FABio::Ordering set in the program. This is deprecated. It does NOT do the right thing with the new FAB I/O format. More...
