Image Deep Zoom

Provides seamless viewing & zooming of huge imagesLoads only the data necessary to show the part of an image the user is viewingEffectively turns a large image into an efficiently scaling vector

Image Deep Zoom

Preprocessing tool breaks image into 256 x 256 tilesThen generates pyramids of tiles at lower resolutions

Deep Zoom – How does it work?

When the image is displayed on the client the lowest resolution tiles are shown firstThen as the higher quality tiles are downloaded, they are smoothly blended in
