RegionErosion

RegionErosion[reg, r] gives the erosion of the region reg by a disk of radius r centered at the origin.

• RegionErosion[reg1, reg2] gives the erosion of the region reg1 by the region reg2.
• RegionErosion[reg1, reg2, {u, v}] gives the erosion of reg1 scaled by a factor u and reg2 scaled by a factor v.

Examples
