It would push outward or inward in two parallel directions perpendicular to the brush stroke direction. For example I could trace through the center of a curvy snake or rope, or legs, nose bridge etc. and enlarge or shrink it evenly on both sides.
Hi Jeff. The pucker and bloat tool squeezes and expands radially. I need a tool that does it bidirectionally perpendicular to my stroke. So if I drag down then it's squeezing or expanding in the left and right directions only.
