Jan,

Perhaps.

One thing I'm concerned about is whether things will continue to work if you
have an "upside down" image - one for which the sixth geotransform[] value is
positive instead of the more conventional negative.

Of course, for such images the concept of ymin and ymax will no longer be
strictly accurate either.

I blame it all on the guy who implemented -projwin!  (sorry, that's a bit
of a joke since I think it was Matt).

Best regards,
