Question

What are Tiled TIFF or SVS image files?

Answer

Whole slide images can be very large (100,000x100,000 pixels)—too large to fit in the memory of most computers. So, the technique of slicing the image into smaller tiles was conceived to allow these images to be displayed.

TIFF (Tagged Image File Format) is a file format for storing images. TIFF files support multiple "pages" or images as well as a variety of storage formats and compression methods. Among these is the Tiled TIFF storage format.

A Tiled TIFF image is composed of many square tiles of the same size (typically 256x256 pixels).

The advantage of the tiled format is that extremely large images can be loaded and displayed efficiently by only loading those tiles that are absolutely necessary (rather than a single, large image).
