SilverZoom is a Silverlight 1.0 control to allow fast, dynamic, interactive zooming for high resolution images. It uses a multi-level tiling algorithm to load only those tiles needed to display an image in the best quality possible. The project comes with a command-line-based/batch-enabled converter tool to produce the necessary tiles from a high resolution image.
SilverZoom is supposed to be used in modern eShops and online catalogues to enhance the shopping experience.
