## The Tags

Certain metadata tags are set by almost all image stages and are known as the “classical” metadata tags:

- width and height
- datatype
- colorspace
- dynamic range
- background and nodata pixel values
- geospatial (x,y) origin, x- and y-resolution, and rotation
- original file size
- original filename

The corresponding image tag names can be found in the `LTIMetadataTag` enum. See "Metadata Tags" for further details.
