PixelYDimension
Information specific to compressed data. When a compressed file is recorded, the valid height of the meaningful
image shall be recorded in this tag, whether or not there is padding data or a restart marker. This tag should not
exist in an uncompressed file. For details see section 2.8.1 and Annex F. Since data padding is unnecessary in the
vertical direction, the number of lines recorded in this valid image height tag will in fact be the same as that
recorded in the SOF.

ComponentsConfiguration
Information specific to compressed data. The channels of each component are arranged in order from the 1st
component to the 4th. For uncompressed data the data arrangement is given in the PhotometricInterpretation tag.
However, since PhotometricInterpretation can only express the order of Y,Cb and Cr, this tag is provided for cases
when compressed data uses components other than Y, Cb, and Cr and to enable support of other sequences.
