  • receiving a user input comprising at least an area in said two dimensional image in which the object to be shadowed resides, an area in said two dimensional image in which the shadow is to be generated and at least one shadow characteristic;

    generating in accordance with said user input a two dimensional artificial shadow;

    manipulating elements stored in said first two dimensional format in accordance with said artificial shadow, said user input and said second format;

    manipulating elements stored in said second two dimensional format in accordance with said user input; and

    defining a relationship between said manipulated elements in said first two dimensional format and the manipulated elements in said second two dimensional format, and generating said two dimensional image with the artificial shadow, based on said relationship.
