Hi, Sorry, I saw the mail during the weekend but was a bit too busy to immediately reply. All dynamics apply as a multiplier to some base value - usually on what is set by the sliders. so there is base size and a dynamics driver, say presure velocity or direction alters it. Most dynamics applications only make the value smaller - there is only one exception - spacing. spacing is varied between set value and sliders maximum value. Direction is one of the trickier dynamics drivers. It's easyest to understand when mapped to angle, but can be useful with others as well. Each angle of movement relative to paper is given a direction of motion value as a fraction of the full circle. I can be used to emulate a lopsided brush for example, strokes one direction can be much thinner than in the other. best, alexia _______________________________________________ gimp-developer-list mailing list gimp-developer-list@xxxxxxxxx https://mail.gnome.org/mailman/listinfo/gimp-developer-list
