A digital image transformation environment is described that employs spline handles. A spline handle is generated by a spline handle generation module of the computing device based on a segment with respect to artwork in a digital image as including control points. A second user input is then received as moving an internal point on the spline handle between the first and second endpoints from a first location to a second location in the user interface. In response, the spline handle generation module regenerates the segment of the spline handle as including the internal point at the second location by adjusting a tangent handle. Next, a digital image transformation module is employed to determine a transformation to be applied to the artwork based on the regenerated segment of the spline handle, which is applied to the artwork.
