To enable a graphic to be subject to translation (a), rotation (b) or size change (c), using only the minimum of commands, a first 'bind point' 120 is defined on the graphic and depending on the position of the ensuing cursor, the desired editing is selectively performed, ie cursor on the bind point gives translation, cursor on one side gives rotation and cursor on a point opposite the bind point gives size change. |
