Methods and apparatus, including computer program products, implement techniques for modifying an image. A warping tool has a perimeter having a shape and a size. The warping tool has one or more associated vectors each of which originates at a mesh point defined by a tool mesh associated with the warping tool. User input is received specifying one or more of the shape of the perimeter, the tool mesh, and the associated vectors. The warping tool is used to modify the image.
