The website is a project from Microsoft Live Labs. The main aim of seadragon website is to change the way we have been using screens to display images. Images can be viewed in wall-size displays and all the way down to mobile phones enabling smooth browsing of graphics and photos regardless of the amount of data or the bandwidth of the network.



Create your own. Just give us the URL to an image on the web.

We shall see the main features that offers for viewing images:

1.Speed of navigation is independent of the size or number of images
2.Performance depends only on the ratio of bandwidth to pixels on the screen
3.Transitions are smooth as butter
4.Scaling is near perfect and rapid for screens of any resolution

Method of use: allows you to share any image on the web as zoomable photo. As seen in the above image you can enter the url of the image that is stored anywhere on the web and click on the create button. In no time flat you have got the zoomable viewer with four option buttons to enlarge or compress the image as seen above. You can now share this link on to your Facebook, Twitter, or email and also directly embed them on your blog. Once the image is embedded on the pan as above you can click on the image to zoom in, use the mouse wheel to zoom in and out, and also drag it to pan around. The image to be embedded can be of any megapixel size. The viewer that is embedded adjusts dynamically to the layout of the page. A few sample images are also displayed on the sides.

Modes of view:

The different modes are Seadragon Ajax, Seadragon, Mobile and Silverlight Deep Zoom.

1. Seadragon Ajax:

We would like to see the image closer, to get a good look at the texture of a sculpture. Seadragon Ajax enables the same as can be seen from the below pictures. Seadragon Ajax brings Deep Zoom technology right on to your web page or blog even if you are not a software developer. It enables you to smoothly zoom into extreme close-ups of your images, regardless of the size of the screen or bandwidth of the network you are using.



2. Seadragon Mobile:

Image browsing goes on from PC to Mobile. The same smooth browsing and super-close view of either a map or photo is available on Mobile phones also, with just a few taps or pinches of your finger. You can also browse a collection of photos from a single screen.


You can even avail Seadragon Mobile from the iTunes App store. I list down the steps to rock your iPhone:

1.Install Seadragon Mobile from the iPhone App Store
2. Launch the Seadragon application on your iPhone
3. Click the ‘+’ button to add content to the Seadragon app
4. Click the ‘RSS Feed’
5.Type in this URL
Click “Done”
7.Click “All Memorabilla”

Silverlight Deep Zoom:

This is more similar to Seadragon Ajax except the fact that we use Silverlight for Deep Zoom.


In Ajax the framerate is slower. In Silverlight the image also blends with the viewer and there is direct bitmap manipulation. Moreover we can also put the images in a gallery aas a collection.
