What if we can think of a way of hint up values for the UI, but not constrain the operator values themselves by these values - so that one could make a 2000-radius gaussian blur, if really needed? (despite any UI changes themselves to allow suitable ranges depending on the image size for certain controls? - (brush radius and gaussian blur come to mind) ) > > Thank you, > > Téo > _______________________________________________ > gimp-developer-list mailing list > List address: [email protected] > List membership: https://mail.gnome.org/mailman/listinfo/gimp-developer-list _______________________________________________ gimp-developer-list mailing list List address: [email protected] List membership: https://mail.gnome.org/mailman/listinfo/gimp-developer-list
