Of course it does not, and this is more or less hidden in the manpage of
generatekeys. However, the behaviour detailed there is not in sync anymore with
the 1.4 version. I now changed the generatekeys behaviour to (in the next
released version):

No option -> doubling of resolution.
zero/0 as downscaleResolution -> image is unchanged.
any positive integer value -> image is downscaled so its longer dimension is as
   long as the given resolution. If the image is smaller, its not changed.

Though I am myself not convinced that its the best way. For generic tasks it is,
but for the use of panorama image stitching maybe I will exchange the first two
behaviours, so no option means the image is unchanged.


For your autopano-complete.sh script, shall I change it by default to use a
size of 700 in the next release?

Btw, for those brave Windows users of autopano-sift 1.4, the downscale
exception bug reported here is currently under investigation by the Gtk#
developers and will most likely be fixed quickly, as it affects a lot of other
functions, too.


bye,
Sebastian
