Claim:
A non-transitory computer readable medium encoded with a computer program, the program comprising instructions that when executed by a data processing apparatus cause the data processing apparatus to perform operations comprising: displaying an image on a display device associated with a computer; displaying a cursor over a region of the image, the cursor including an inner periphery that defines an inner area, an outer periphery that defines an outer area between the inner periphery and the outer periphery, and an effect indicating periphery between the inner periphery and the outer periphery; and in response to receiving input to apply an effect at the region: applying an effect at the region: to a first intensity within the inner area defined by the inner periphery, variably across the outer area defined between the inner periphery and the outer periphery, the effect being graduated from the first intensity at the inner periphery to a second intensity at the outer periphery according to an intensity distribution, determining an intensity of the distribution that is based on the effect applied at the region, and is between the first intensity and the second intensity, and displaying the effect indicating periphery along the intensity of the distribution.
