How does deep zoom work?

While zooming, it continuously loads the appropriate tiles from a tile pyramid, so you can move seamlessly down to the finest details.

A viewing technique allowing seamless, smooth zooming into extremely high-resolution images – based on a tile pyramid.

Deep zoom denotes the interactive viewing technique that allows seamless, smooth zooming into gigapixel and terapixel images – from the overall view down to the smallest details at full resolution.

Technically, deep zoom is based on a tile pyramid: while zooming, the appropriate tiles are continuously loaded at the required resolution. This creates the impression of a seamless, endless journey into the image, without the entire volume of data having to be loaded at once.

Deep zoom makes the true value of high-resolution images tangible, as the finest structures only become visible on zooming in.
