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).
