T.4 FAX compression metadata descriptor. This contains information about the image which may be relevant to the backend, but is not generally relevant to the image encoding process. The exception here is the y-resolution, which is used in T.4 2-D encoding for non-ECM applications, to optimise the balance of density and robustness.
