TAG_COMPONENTS_CONFIGURATION top-level constant

String const TAG_COMPONENTS_CONFIGURATION

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 TAG_PHOTOMETRIC_INTERPRETATION. However, since TAG_PHOTOMETRIC_INTERPRETATION 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.

 Length = 4
 Default = 4 5 6 0 (if RGB uncompressed) or 1 2 3 0 (other cases)
     2 = Cb
     3 = Cr
     4 = R
     5 = G
     6 = B
     other = reserved

Implementation
