• ImageViewer4x: An image viewer using swt. A GC can be created on an Image and then use it to draw into the Image. To display very large image, pixel data is loaded into ImageData and then tiles of the data are used to create Image's for display. This is an experimental version modified from ImageViewer3. To reduce time lag between clear and update during scroll, a large Image is drawn to the display, so that it would use scroll in the offscreen image instead of wait for update from the PaintEvent. The PaintEvent then fill up the offscreen section that are scrolled away. Update is much faster. There are no visiable ...
