Abstract: An Image Editor includes a ZOOM function wherein other Image Editor actions are invokable and operable in whatever zoom level is currently in effect. The zoom mode is a state of the Image Editor in that invoked actions are performed in a normal 1X pel size image but are displayed to an operator in an enlarged, fat pel, zoom equivalent. When the ZOOM function is invoked a displayed zoom window is automatically centred upon a present position of a cursor as is also a selectively displayable viewport, the viewport showing the relative position of the cursor within the 1X image.
