ZOOMING A DISPLAYED IMAGE

摘要

A system for displaying an image in a viewport is disclosed. A zoom subsystem (6) is arranged for gradually zooming the image (401) towards a scale factor at which the image just fits within the viewport (302), wherein the zoom (6) subsystem is arranged for keeping a fixed point (403) fixed within the viewport (302), wherein the fixed point (403) depends on a pan/zoom parameter (7) of the image (401) at the time zooming starts, wherein the fixed point (403) is a point of the image (401) which is being displayed in the viewport (302) at the time zooming starts, and wherein the image (401) is capable of being zoomed to a zoom level at which the image just fits within the viewport (302), while the fixed point (403) is kept fixed with respect to the viewport (302).
