ABSTRACT:
Displayed picture points are re-locatable in response to manual operation of an interface device such as a stylus or a mouse etc. The interface device is activated, by being placed into pressure or by clicking, and an identified picture point is subsequently moved in response to manual operation of the interface device. In response to said picture point being moved, other picture points are also moved by a displacement which differs from the displacement of the identified picture point and which varies in proportion to the original distance of the other picture point from the identified picture point.
