JEITA CP-3451 - 10 - Table 1 TIFF Headers Name Size (Bytes) Value Byte Order 2 Written as either "II" (4949.H) (little endian) or "MM" (4D4D.H) (big endian) depending on the CPU of the machine doing the recording. 42 2 002A.H (fixed) Offset of IFD 4 0th IFD offset. If the TIFF header is followed immediately by the 0th IFD, it is written as 00000008.H. 4.5.3 Basic Structure of YCbCr Uncompressed Data YCbCr uncompressed data is recorded in conformance with TIFF Rev. 6.0 Extensions YcbCr Images.    Tags for the  following  information  are  available  for  YCbCr  uncompressed  data  in  addition  to  the  attribute  information  for RGB uncompressed data; ·  RGB-YCbCr color transformation matrix coefficients (YCbCrCoefficients), ·  Chrominance subsampling information (YCbCrSubSampling), ·  Information on matching/nonmatching of chrominance and luminance samples (YCbCrPositioning). The method of recording other attribute information is the same as for uncompressed RGB data (see section 4.5.2).
