The general notion of the file height can be broken up into different subsets. Among them are the cropped image height and image width. Like those, the Coded Height describes a very particular height of a file.
The Coded Height differs from the general height in that it’s pre-coded in the file. This means it can but does not have to differ from the original height of the file. This affects images such as pictures and photos, as well as videos, documents and e-books, and even audio files (e.g. when it comes to cover art).
The coded dimensions are made up by the Coded Height and the Coded Width.
