This is a test of pan and zoom interface for large, high-resolution images - based on "GSIV", similar in spirit to Google Maps.
The original image is approx 8000 pixels wide. It has been divided into 256 x 256 pixel tiles. As the image is dragged, tiles are repositioned and requested to maintain the illusion of a single large image.
Use the small control in the bottom right corner of the plot to choose zoom level and maximize the image so it fills the complete screen. Click on image and drag to view desired section.
