# Using the Zarr Tile Sink

The `ZarrFileTileSource` class has file-writing capabilities; an empty image can be created, image data can be added as tiles or arbitrary regions, and the image can be saved to a file in any of several formats.

Typically, this class is called a “source” when reading from a file and a “sink” when writing to a file. This is just a naming convention, but the read mode and write mode are not mutually exclusive.
