In a display including one or more edges that define a display area in which at least a portion of an image including an image edge point is displayed, a method of changing the relative size of the image, comprising the steps of: selecting a zoom point in the displayed image, the zoom point corresponding to a point in the displayed image, the image edge point located at a position on the display area edge that coincides with an edge point on the display area; and changing the relative size of the displayed image while (i) translating the selected zoom point along a straight zoom line that passes through the selected zoom point and extends between a central point in the display area and the display area edge point and (ii) maintaining the position of the image edge point such that the image edge point remains coincident with the display area edge point, wherein, when the selected zoom point coincides with the central point in the display area, the selected zoom point does not translate while the relative size of the displayed image is changing.
