[Gimp-user] "Live" update of selected regions

[Marco Presi]

Hi,

I would like to know if there is a way to update a selection made with
any of the selection tools. After the selection is made I often would
like to make it smoother or to change the threshold (expecially when
selecting by color). Acting on the selection controls (smoothing radius,
threshold, ...) has no effect: in order to make the adjustments, I need
to re-select from scratch the region.

Is there a way to do this without selecting from scratch again and
again?

Regards

Marco
